What are the key considerations when converting a 1771-IA module to a 1756-IA16 module? Answer: Conversion module 1492-CM1771-LD007 and conversion cable 1492-C005005XE are required; 1771-IA module input delays are 24ms (±10ms) on-off, 24ms (±10ms) off-on, 1756-IA16 module is 10ms max on-off (with optional filter) when using this conversion cable. The 1756-IA16 module is rated for 87V – 138V AC and 97V – 138V DC, the 1771-IA module is rated for 79V – 132V AC only.
Wire-free conversion: The I/O conversion process eliminates the need to remove any field wires from the existing swing arm. The conversion module adapts directly to the existing swing arm and transmits the I/O signals to the 1756 I/O module via the conversion module and cables, which greatly reduces the risk of wiring errors, reduces the number of failures caused by wiring errors during system upgrades, and improves conversion efficiency and stability. Pre-wired design: The cables in the system are pre-wired, with one end connecting to the converter module and the other end being a removable terminal block (RTB). This design simplifies the installation process, saves installation time, reduces labour costs, reduces problems caused by improper wiring on site, and improves overall system reliability.
Flexible mounting components: The base plate of the conversion mounting kit has the same mounting holes and dimensions as the 1771 chassis, eliminating the need for re-drilling and tapping in the control cabinet; the cover plate is equipped with pre-drilled and tapped mounting holes, which allows the 1756 chassis to be mounted in left-aligned, right-aligned, or centre-mounted position, facilitating the installation of different installation spaces and layout requirements, and enhancing the flexibility of system installation.
Comprehensive Conversion Adaptation: A wide range of 1771 I/O modules can be converted to 1756 I/O modules, including digital inputs, digital outputs, analogue inputs, analogue outputs, and high-resolution isolated analogue I/O modules. For different types and models of modules, corresponding conversion modules, cables and detailed wiring methods are provided to ensure the accurate conversion and transmission of all types of signals.
Detailed technical specifications and considerations: Each I/O module conversion is clearly given technical specifications and application considerations. For example, input delay time and voltage level of digital input/output module, shield grounding, signal type assumption, input/output range configuration of analogue input/output module, cable length and terminal connection of high-resolution isolated analogue module, etc., which provide comprehensive technical guidance for users in the process of selecting, installing and using, and guarantee the correct operation of the system.

Eingangs- und Ausgangsregister haben in verschiedenen Konfigurationen unterschiedliche Datenformate, und Statuswörter werden zur Anzeige verschiedener Fehler und Statusmeldungen verwendet.
Features of the resolver interface of the 1642 module Connection characteristics: The 18-pin connector used to connect the resolver has several internal pins with specific functions. For example, pin 1 is located in the upper left corner and pins 1, 2, 15 and 16 are ground pins for connecting to the cable shield and reducing electrical noise interference. The function of pins 3 – 10 varies with the type of resolver. The two R1 and two R2 signals of the module are internally connected to facilitate the signal connection to the resolver and ensure the stability of the signal transmission.
Supported types: Compatible with a wide range of resolvers, it can be used with two AMCI single resolvers (e.g. HT – 20 series, H25 – XX series, HT – 20 – X series), or connected to an AMCI dual resolver (e.g. HTT – 20 – X series) or an Autotech dual resolver (RL210 128 turn). For other types of resolver, support is also possible through the use of the AMCI RM reference module, which significantly extends the range of applications.
Electrical characteristics: The resolver is supplied with a reference voltage which can be selected between 5kHz and 2.5kHz. The default value of 5kHz is suitable for most applications, and a setting of 2.5kHz improves system performance when cable lengths exceed 100ft. Rotary transformer signals are low-voltage, low-power signals, the wiring should follow the A – B wiring guidelines, treated as Category 2 cable, and can not be installed in the same pipeline with the AC power line or high-power AC and DC I/O lines, to avoid electromagnetic interference affecting the signal transmission.
Troubleshooting features: Sensor fault detection is available to detect faults caused by improper wiring, electrical noise, or sensor damage. By default, sensor faults are not latched and fault conditions are automatically cleared when a valid signal is detected. However, if transient faults need to be captured reliably, the Sensor Fault Lockout parameter can be enabled, after which a Clear Error command needs to be sent to clear the fault, making it easier for the user to troubleshoot and handle the fault.
Data Processing Features: Converts and transmits rotary transformer position and speed data to the PLC; for single rotary transformer configurations, position (in counts) and speed (RPM) for channels 1 and 2, as well as stopping time and brake application position data for channel 1. For dual resolver configurations, position data is reported in a specific format that splits the position data into two words for easy processing and storage by the PLC, meeting the data requirements of different control scenarios.

Brand Background Hirschmann has a longstanding reputation in the field of network communications, having built the world’s first fibre-optic Ethernet in 1984 at the University of Stuttgart, Germany, and pioneered HIPER – Ring technology in 1990. Its products are used in both industrial and office environments and cover a wide range of applications from Gigabit Ethernet and Fast Ethernet to fieldbus systems and ASI connectors for actuators and sensors. In industrial automation, process control, traffic control and office communication scenarios, Hirschmann products have become the trusted choice of many companies due to their outstanding reliability and stability, providing solid support for the construction of efficient and stable network communication systems. Second, the specification parameters (because we have not found the precise parameters, the following is a similar module speculation)
Port type and number: Referring to the same series of products, it may be equipped with various types of ports, such as 10/100Base – TX electrical port, which is used for connecting traditional Ethernet cables to meet the needs of short-distance equipment access; or 100Base – FX multi-mode SC port, which is suitable for short and medium distances, higher bandwidth requirements and the need for anti-interference fibre optic connectivity scenarios. The number of ports may be set to more than one according to the scale and complexity of the actual application scenarios to achieve efficient
interconnection between multiple devices. Transmission rate: It is likely to support Fast Ethernet standard, i.e., 100Mbps transmission rate, to guarantee the fast transmission of data in the network and to meet the business needs of general industrial control and office network with small data volume but high real-time requirements. For some application scenarios with higher requirements for data transmission, it is not excluded that it has the ability to work with other high-speed modules to achieve higher bandwidth.
Performance characteristics High reliability: Based on Hirschmann’s mature industrial-grade design concept, the module can adapt to the harsh working environment. With excellent anti-electromagnetic interference capability, it can effectively avoid data loss or incorrect transmission due to signal interference in strong electromagnetic environments, such as industrial production workshops, ensuring stable and reliable data communication. At the same time, it can also maintain normal operation under complex conditions such as mechanical vibration and temperature changes, reducing equipment failures caused by environmental factors. Efficient Data Processing: Advanced data processing chips and algorithms are used internally, which can quickly debug and demodulate Ethernet transmission signals, and accurately convert differential signals on the network line into digital signals recognisable by the CPU. When the data traffic is large, the optimised caching mechanism and data forwarding strategy can also guarantee the high efficiency of data processing, reduce the transmission delay and improve the overall network performance.
Model supplement In the Hirschmann Ethernet module product line, the GMM 20 series is also available in many different configurations. For example, some models may have different port combinations, some focus on more electrical port configurations, which are suitable for networks with traditional cable-connected devices, while others increase the number of optical ports to meet the needs of long-distance, high-speed optical communication. There are also models that expand on functional features, such as support for specific network protocols, in order to adapt to the special requirements of specific industries or application scenarios. These different models together constitute a rich product matrix to meet the diverse needs of network construction.
Scenario Applications Industrial automation production: In automated production lines, the module can connect various types of sensors, controllers, actuators and other equipment. The data collected by the sensor is quickly transmitted to the controller for analysis and processing, and the controller sends commands to the actuator through the module according to the analysis results to achieve accurate control of the production process. For example, in automobile manufacturing factories, this module ensures efficient communication between various production line equipment to improve production efficiency and product quality.
Intelligent traffic monitoring: Used in traffic signal light control system, the module can transmit real-time signal light status data to the traffic management centre, and at the same time receive control instructions from the centre to adjust the signal light timing. In the highway monitoring system, the video data collected by the camera can be quickly transmitted to the monitoring centre to provide a basis for traffic management decisions and ensure road traffic safety and smooth flow. Enterprise office network: In the enterprise office environment, office computers, printers, servers and other equipment can be connected to build a stable internal local area network. Employees can quickly access shared files and use network printers, and the server can efficiently provide data services for each terminal device to enhance the efficiency of corporate office and information technology.
Precautions Installation environment: Avoid installation in high temperature, humidity or strong corrosive environment. High temperatures may lead to a decline in the performance of the module’s internal electronic components, shortening the service life; humid environments are prone to cause circuit short-circuit failures; strong corrosive gases or liquids may erode the module shell and internal circuits, damaging the equipment. It is recommended to install the module in a well-ventilated environment with suitable temperature (generally 0 – 50℃) and moderate relative humidity.
Connection Adaptation: Ensure that the specification of the connected cable matches the module port. Using cables that do not meet the specifications may result in severe signal degradation, reduced transmission rates, or even failure to communicate. For example, when connecting a 100Base-FX optical port, use a fibre optic cable of the corresponding specification, and make sure that the type of fibre optic (singlemode or multimode) is compatible with the module. At the same time, when connecting the electrical port, choose an Ethernet cable that meets the standard, and ensure that the cable is of good quality, with no damage or breakage.
Network Configuration: Before connecting to the network, it is necessary to correctly configure the network. According to the IP address planning of the network, set the IP address, subnet mask, gateway and other parameters of the module. Incorrect network configuration will result in the module not being able to communicate normally with other devices. If it involves complex network environment, such as the existence of VLAN delineation, routing settings, etc., it requires professional personnel to carry out fine configuration to ensure the stable operation of the module in the network and accurate data transmission.
Introduction of Hirschmann MM20 – T1T1T1EBHH Managed Ethernet Switch Hirschmann has rich experience in industrial networking, MM20-T1T1T1EBHH managed Ethernet switch is designed for harsh industrial environments, providing network communication security for complex scenarios.
Brand Background Founded in 1924 in Esslingen, Germany, Hirschmann built the world’s first fibre-optic Ethernet in 1984 and introduced ring-redundant Ethernet in 1990, which significantly improved network stability, and continued to expand its business and introduce new products after it was incorporated into Biotronik in 2007.

Brand Background Hirschmann has been a mainstay in the field of industrial networking since its founding in 1924 with a factory in Esslingen, Germany. 1984 saw the establishment of the world’s first fibre-optic Ethernet at the University of Stuttgart, Germany, which revolutionised industrial network communications, and 1990 saw the world’s first HIPER-Ring (Redundant Ethernet), a solid foundation for stable operation of critical systems in complex environments.
In 1990, the company was the first in the world to introduce HIPER-Ring (Redundant Ethernet), which laid a solid foundation for the stable operation of critical systems in complex environments. In 2007, Hirschmann became a part of Baxter, Inc. to further expand its business with new resources. Hirschmann entered the industrial network market earlier, with its deep technical accumulation and keen insight into the market, the product application areas are extremely wide, covering office communications, production automation, process control, traffic control, and independent machine control systems and other industries, of which the advantages in the power and traffic industry is particularly significant.
Second, the performance characteristics High Reliability: To cope with the complexity of industrial environments, the MM20 – M4M4M4SYHH switch adopts a redundant design. In terms of power supply, it is equipped with redundant power supply modules or supports dual power inputs. When the main power supply fails suddenly, the backup power supply can be seamlessly switched in a very short time to ensure the continuous and stable operation of the switch, effectively avoiding network paralysis due to power supply interruption, which is of great significance for the critical industrial production links that cannot be easily shut down. In terms of link redundancy, it supports link aggregation technology, which bundles multiple physical links into one logical link, not only increasing the link bandwidth, but also providing link redundancy, so that when one of the physical links fails, the data can be automatically switched to other normal links for transmission, ensuring the continuity of network communication.
Meanwhile, the switch has a powerful self-diagnostic function, through the internal integrated intelligent monitoring chip and software algorithms, it can monitor its own hardware status in real time, such as whether the ports are damaged, whether the temperature of the chip is too high, whether the memory reads and writes normally, etc. Once the failure is detected, it will immediately notify the operation and maintenance personnel through the indicator light, alarm message and other ways, which provides a strong support for the rapid troubleshooting and repair of the problem.
Powerful network management capability: supports multiple management methods, which greatly facilitates the operation needs of different users. Users can manage the switch through the web interface. Simply enter the IP address of the switch into the browser and enter the intuitive management interface, where you can easily set various parameters of the switch, such as port configuration, VLAN delineation, QoS policy, etc. For professional network engineers who are familiar with command operation, it is very convenient for them to manage the switch in a convenient way. For professional network engineers who are familiar with command operation, the switch also supports command line interface (CLI) management, which provides a more accurate and efficient way of configuration and is suitable for in-depth configuration and troubleshooting in complex network environments.
In addition, the switch may also support centralised management through dedicated network management software, which allows administrators to carry out unified monitoring and management of multiple switches distributed in different areas in large industrial networks, greatly improving management efficiency. In the details of network management functions, the fine VLAN delineation function can divide a physical network into multiple logically independent virtual LANs. In industrial environments, different production segments, departments, or devices may need to be isolated from each other in order to improve the security and management efficiency of the network, for example, by dividing the network where the production equipment is located and the network in the office area into different VLANs, it can prevent viruses or unauthorised access to the office network from causing damage to the office network.
For example, dividing the network where the production equipment is located and the office area network into different VLANs can prevent viruses or illegal access in the office network from affecting the normal operation of the production network, and at the same time, the VLAN division can optimise the network traffic, reduce the interference of broadcast storms, and improve the overall performance of the network; QoS (Quality of Service) settings are supported, and the requirements for network bandwidth and transmission latency are different for different types of data traffic in an industrial network. With QoS function, administrators can set different priorities for different traffic according to the type and importance of data to ensure priority transmission of business-critical data and stable operation of industrial production processes.
Excellent adaptability to industrial environments: The temperature environment of industrial sites is complex and variable, from high-temperature metallurgical workshops to cold storage environments. MM20-M4M4M4SYHH managed Ethernet switches have a wide operating temperature range, generally adapting to temperatures ranging from -40°C to +70°C or even worse, enabling stable operation in various extreme temperature environments and guaranteeing reliable communication of industrial networks.

Outstanding environmental adaptability: With an operating temperature range of -40°C to +70°C, the switch can work normally in cold outdoor environments (e.g., connecting network devices in polar research stations) or hot industrial plants (e.g., steel smelting workshops), ensuring uninterrupted network connections. The protection level meets IP65/IP67 standard, with excellent dustproof and waterproof ability. In dusty mining environments or on the decks of ships prone to water splashes, it can effectively resist the intrusion of dust and water, protect the internal circuitry and extend the service life of the equipment. Anti-vibration and anti-shock performance in line with industrial standards, in the vibration and shock of industrial environments (such as factories, production lines, rail vehicles), can be solidly maintained in the working state, to maintain the stable operation of the network.
Comprehensive network protocol support: Support for VLAN (Virtual Local Area Network) allows users to divide the network into multiple logical subnets to improve network security and management efficiency. For example, in large factories, devices in different production areas can be divided into different VLANs to achieve data isolation, preventing data interference between different areas and facilitating traffic control and resource allocation. It supports QoS (Quality of Service), which assigns different priorities to different types of data (e.g., voice, video, control commands, etc.) to ensure the transmission quality of critical data. In remote monitoring systems, video data and control commands can be given higher priority to ensure smooth monitoring images and timely delivery of control commands. Support port mirroring function, which is convenient for network administrators to monitor and analyse network traffic, detect network failure or abnormality in time, and ensure normal operation of the network. Support RSTP (Rapid Spanning Tree Protocol), MSTP (Multiple Spanning Tree Protocol) and other redundant protocols to enhance network stability. When a link failure occurs in the network, it can be quickly switched to the backup link to ensure that network communication is not interrupted, and enhance the reliability of the network.
Convenient and efficient management function: Support SNMP (Simple Network Management Protocol), which can achieve remote network management, administrators can monitor and configure the switch through the network, without the need to visit the site, improving management efficiency. Web management interface, intuitive and convenient operation, no need for professional command line operation skills, lowering the threshold of management, ordinary technicians can easily get started. Supports CLI (command line) configuration, providing professional network engineers with more accurate and flexible configuration methods to meet the advanced configuration needs of complex network environments.
Heat dissipation speculation Natural Heat Dissipation: Many industrial Ethernet switches use natural heat dissipation, which is achieved by the large metal surface area of the device casing. MM20-M2T1T1SAHH may also make use of this method, as its casing is designed to have a large surface area for heat dissipation, and the metal casing is able to absorb the heat generated by the switch’s internal electronic components quickly, and emit the heat into the surrounding air. This way, in some industrial scenarios where the heat dissipation requirements are not particularly high and the ambient temperature is relatively stable, natural heat dissipation alone can satisfy the temperature requirements for normal operation of the switch. For example, in the indoor office automation network environment where the heat generated by the equipment is small, the natural heat dissipation can ensure the stable operation of the switch.
Heat sinks: To enhance heat dissipation, some of Hirschmann’s switches may be equipped with heat sinks on key heat-generating components. the MM20 – M2T1T1SAHH may also be equipped with heat sinks, which are usually made of metals with good thermal conductivity, such as aluminium or copper. They fit snugly on the surface of heat-generating components like chips, greatly increasing the heat dissipation area and speeding up the rate at which heat is dissipated. When the switch is in operation, heat is conducted from the heating element to the heat sink, and then emitted from the heat sink to the surrounding environment, effectively reducing the temperature of the component.
Optimisation of heat dissipation in a compact structure: Considering the compact design of the switch and its limited internal space, the design of the heat dissipation system needs to make full use of the limited space. A design that combines heat dissipation channels with the internal layout may be adopted to ensure that air can flow reasonably inside the switch and carry away heat. For example, the design of the circuit board will plan the location of heat-generating components so that air can flow smoothly through these components to improve heat dissipation efficiency. At the same time, reasonable arrangement of internal wiring, to avoid the line to block the air flow, to ensure that the heat can be smoothly transferred to the shell or heat sink for dissemination.
Adaptation to harsh environments: As an industrial switch, it needs to work in a variety of harsh environments, and its heat dissipation system should be able to adapt to different environmental conditions. In a high temperature environment, the cooling system should ensure that the switch will not overheat and performance degradation or failure; in a low-temperature environment, it should prevent the electronic components from unstable performance due to low temperature. Therefore, the cooling system may have certain temperature adjustment functions, such as intelligent control of the heat dissipation efficiency of the heat sink, to maintain the appropriate working temperature inside the switch in different temperature environments.
Influence of Heat Sink on Switch Performance Ensure stable operation: A good heat dissipation system is essential to maintain the stable operation of the switch. If the heat dissipation is poor and the internal temperature of the switch is too high, it will lead to the performance degradation of electronic components, data transmission errors, port failures and other problems, which will seriously affect the stability and reliability of the network. An effective heat dissipation system ensures that the internal temperature of the switch remains within a reasonable range over a long period of time, guaranteeing the normal operation of the ports and maintaining high-speed and stable data transmission.
Extend service life: A proper heat dissipation system helps to extend the service life of the switch. When the electronic components work under the appropriate temperature, their aging rate will be significantly slowed down, thus reducing the equipment failure caused by component damage.MM20 – M2T1T1SAHH’s cooling system can effectively control the temperature, which can reduce the failure rate of the components, so that the switch can operate stably for a long period of time in industrial environments, and reduce the cost of equipment replacement and maintenance.
