Performance Advantages
High-speed communication: PROFIBUS DP supports a transmission rate of up to 12 Mbit/s, which can quickly realise data interaction between the controller and decentralised peripheral devices, meet the strict requirements for real-time in industrial sites, and transmit data in time to ensure efficient system operation in production scenarios that require high response speed.

Powerful diagnostic function: the slave can provide rich diagnostic data, covering channels, modules and a variety of error messages related to the slave. The system can effectively process and map these data, and clearly present errors or warnings in Control Builder M, making it convenient for engineers to quickly locate and solve problems, and improving system maintenance efficiency.

Highly redundant design: Supports a variety of redundancy methods, including master unit, slave unit and line redundancy. Different types of redundancy can be configured independently or in combination. For example, in critical production processes, redundancy can ensure stable operation of the system in the event of partial equipment failure, which greatly improves the reliability and availability of the system.

Flexible Configuration Capability: With Control Builder M, it is easy to insert and manage master and slave units, and to set the parameters of the equipment flexibly. It also supports online change of part of the configuration without interrupting the system operation, which improves the maintainability and adaptability of the system and facilitates timely adjustment of the system configuration according to the production demand.

Specification
Hardware related: Master unit CI854/CI854A node address range is 1 – 125; baud rates of 9.6, 19.2, 93.75, 187.5, 500, 1500, 3000, 6000 and 12000 kbit/s are supported; parameters such as slot time, min. station delay, max. station delay, and so on, have corresponding ranges of values, and some of the parameters will be automatically calculated according to the configuration. Some of the parameters are calculated automatically according to the configuration.

Data transmission: In cyclic data communication between master and slave units, the master unit can write up to 244 bytes of output data and read up to 244 bytes of input data to the slave unit each time; in acyclic data communication, the maximum data block size is 244 bytes, and the transmission priority is lower than that of cyclic data communication.

Time parameters: watchdog time should be set reasonably according to the baud rate and system reaction time; target rotation time TTR is used to plan the network cycle time, which needs to be considered for all kinds of communication requirements in the system; quiet time, setup time and other parameters have their own roles and ranges of values, which work together to ensure the stability and accuracy of data transmission.

PROFIBUS Technical Basics
Overview of the protocol: PROFIBUS is the fieldbus standard for industrial automation and consists of two protocols, DP and PA. DP is used for communication between controllers and decentralised peripheral devices and has a high transmission rate, while PA is specially designed for the process industry and supports bus power supply and intrinsic safety, has a transmission rate of 31.25 kbit/s, and can be integrated into the DP network by means of a link device.

Technical terminology: ISO/OSI reference model, bus-specific access control and addressing. Device addresses are 7-bit, range 0 – 127, some addresses have special uses, functions vary between protocols, AC 800M/CI854 (A) supports basic and extended functions.

Transmission technology: RS485 is widely used and supports a variety of rates, the cable type affects the transmission distance and performance; RS485 – IS is used in intrinsically safe areas; MBP adopts Manchester encoding and supports bus power supply and intrinsic safety; fibre-optic transmission is suitable for strong electromagnetic interference or long-distance scenarios, and there are a variety of cable types to choose from.

Fieldbus Topology
Common topologies: point-to-point, line, line with branch, tree, star and ring topologies. Each topology has different characteristics and is applicable to different scenarios, e.g. point-to-point is used for specific sub-segment connections, ring topology has high network security.

RS485 (PROFIBUS DP) topology: the bus length is related to the transmission rate, correct terminal matching is required, 9-pin D-Sub connectors are used, attention is paid to the shielding and data line connection, avoiding the use of passive branch cables, the maximum number of devices to be connected to the network segment is 32, which can be extended by repeaters.

MBP (PROFIBUS PA) topology: Tree or line structure, fixed transmission rate, cable length subject to a variety of factors, intrinsically safe installation needs to follow the FISCO model, both ends of the bus need to be correctly terminated to match the length of the branch line has a limit.

Fibre optic topology: bus, star or ring network can be constructed, with various transmission rates, anti-interference, long distance transmission and other advantages, through the optical link module to achieve the electrical and optical network conversion, different topologies have different settings and requirements.

System redundancy design
Redundancy concept: covers controller, line and slave redundancy. Controller redundancy is realised by the CI854A module, which is automatically activated in the event of a failure; line redundancy requires redundant transmission media and bus connections, which are supported by the CI854A, and single-interface slaves can be connected to the redundant line with the help of the RLM 01 module; slave redundancy consists of redundant links/gateways and optional I/O modules.

RLM 01 module: Converts redundant and non-redundant PROFIBUS lines, supports a wide range of rates, communication monitoring, relaying, etc. Attention should be paid to port connections, terminating resistor settings and transmission rate selection during installation.
PROFIBUS device commissioning

Cable Installation: Electrical data cable installation should avoid damage and follow the operation specification; fibre optic cable installation should pay attention to cleanliness, avoiding stress, and selecting appropriate cables for different scenarios; PROFIBUS DP installation has special grounding and shielding requirements, and devices such as the CI854 (A), RLM 01, and LD 800P have specific steps and

precautions for installation.
Network Testing and Problem Solving: Test bus cables and connectors after installation to troubleshoot common errors. The document provides solutions and recommendations for common installation problems, such as address conflicts and polarity errors, as well as ways to obtain more information and purchase related components.

Technical Characteristics
Transmission technology: MBP (Manchester Coded, Bus Powered) transmission technology, i.e. Manchester Coded and Bus Powered. The transmission rate is fixed at 31.25 Kbit/s. This synchronised transmission allows intrinsically safe communication in potentially explosive areas. Shielded twisted-pair cables are used as the transmission medium. The cables have specific parameters, such as a conductor cross-section of 0.8 mm², a wave impedance of 100 Ω ± 20%, etc., and the cable colours are differentiated in different areas, black in non-hazardous areas and blue in hazardous areas.

Network structure: Supports tree or line structure, or a combination of both. In the tree structure, the devices are connected to the trunk cable through branch lines, similar to the traditional on-site installation method; in the line structure, the devices are connected to the trunk cable sequentially. These two structures facilitate the flexible construction of the network according to the layout of the field equipment, but in the calculation of the total length of the bus, you need to take into account the maximum permissible length of the branch line.

Intrinsically safe: The design is based on the FISCO (Fieldbus Intrinsically Safe Concept) model, which is based on a number of prerequisites to ensure intrinsic safety. For example, only one active source (usually a link device) is allowed on the bus segment, the other components are passive current absorbers; the basic current consumption of the bus station is at least 10 mA; specific voltage, current and power relationships are met, as well as capacitance and inductance limits.

Device connection and power supply: PROFIBUS PA devices are mostly connected to the network by means of multibarries or T-junctions; the branch lines can be connected directly to the connector blocks inside the device, or M12 plugs are used. The power supply of the devices is realised via the bus. In intrinsically safe applications, there are limits on the supply voltage and current, e.g. 100mA in hazardous areas and 400mA in non-hazardous areas.

Data communication: The format of the data telegrams is similar to asynchronous RS-485 transmission, but the transmission of the MBP segments is bit-synchronous and the telegrams are supplemented with a leading code and start and end delimiters. Data security is achieved by parity and block checking with a Hamming distance HD = 4 and up to three errors can be detected.

Network limitations: up to 32 devices per network segment, but the actual number is limited by the type of protection and bus power. The maximum line length of the network can be up to 1900 m in non-intrinsically safe areas and 1000 m in intrinsically safe areas, depending on the power consumption of the devices and the type of cable selected.

The power consumption of the module is 3.5W, powered by dual redundant SC300E power supply units, with independent power supplies for the optical isolators and interfaces of the communication ports. It supports single-slot hot-repair and has a switch on the front panel for requesting the module to go offline. The front panel is also equipped with Tx, Rx, Health, and 3 On Line indicators to show the module’s working status.

Purpose: Provides a serial interface between the SC300E system and RS232-C compliant remote devices. At least one of these modules needs to be installed in Slot 10 of the main chassis to enable communication between the system processor and workstations for loading application software, monitoring ladder diagrams, and diagnostic functions. Additional modules can be installed in other I/O slots, with mechanical coding blocks to prevent misplacement.

Principle of operation: Data is fed into and out of the module via chassis backplane connector J1 and isolated from the MPP via the bus transceiver. When sending data, it is first loaded into the dual-port RAM, and then serialised and sent after 2 – oo – 3 votes; when receiving data, it is converted to parallel form by USART and written into the dual-port RAM, and then read by MPP. The communication port is an RS232 interface in full-duplex mode at a maximum rate of 19200 Baud, isolated from the module circuitry by an opto-isolator, and can drive a modem or line driver.

Maintenance and Service: Modules contain static-sensitive components and need to be shipped and stored in their original packaging. Failed modules are not repaired in the field and should be returned for service. Troubleshooting is performed using a TriBuild workstation and the faulty module health LED will go out. Take the module offline before removing it and take care to align the markings when inserting a new module. The module does not require preventative maintenance and spare parts and technical support are available from your local office.
