When in use the equipment has to fulfil specific conditions, such as protection against UV rays, avoidance of voltage overruns, etc.
Module Installation Preparation for Installation: The module should be mounted on a 1794 series terminal block, ensuring that no debris falls into the module prior to installation and that plugging or unplugging the module while it is energised may be hazardous. Installation Procedure: Turn the key switch to position 2, make sure the Flexbus connector is fully extended, insert the module and align it with the notch for a secure installation. Wiring Methods: Wiring methods vary between module models (1794-OB8, 1794-OB8EP, 1794-OB16, 1794-OB16P, 1794-OB32P). Output, power, and common wires need to be connected according to specific rules, and the power supply can be daisy-chained, and the total current must not exceed 10A.
Module Configuration 1794 – OB8EP Module: Configured by setting bits in the configuration word, fault bits can be programmed to detect faults, and faults can be reset by pushbuttons, programming, or cycling the backplane power. Other modules (1794-OB8, 1794-OB16, 1794-OB16P, 1794-OB32P): Configuration by setting the bits in the configuration word (word 3).
Note Zone Classification and Equipment Suitability: 1794-OB8 is suitable for use in North American Class I Division 2 Groups A, B, C, and D hazardous areas and European Zone 2 hazardous areas, but cannot be used in other hazardous area classifications. Hazardous area temperature codes are marked on the product nameplate. When using the product in a system combination, the most unfavourable temperature code (the lowest ‘T’ number) must be used to determine the overall system temperature code, and the combination of equipment must be reviewed by the local regulatory agency.
ELECTRICAL SAFETY OPERATIONS: Disconnecting equipment or connections while energised is strictly prohibited, and before operating in a hazardous area, you must either disconnect the power supply or ensure that the area is free of hazards. Plugging and unplugging modules under electrical power can cause arcing, which may result in an explosion, as well as wear and tear of the module and connector contacts, which can interfere with the normal operation of the equipment. When used in hazardous areas, prevent the rated voltage from exceeding the specified value due to transient disturbances, e.g. in European Zone 2 environments, take measures to ensure that transient disturbances do not cause the voltage to exceed 40% of the rated value.
Installation and earthing of the device: The device must be installed in a compliant enclosure with a minimum IP54 protection rating (required for European Zone 2 environments), with the interior accessible only by means of a tool, and with suitable flame retardancy to prevent the spread of flame. Use zinc-plated yellow chrome steel DIN rails for earthing, avoiding corrosive, oxidising or poorly conductive rail materials such as aluminium or plastic to prevent poor earthing. Securely fasten DIN rails to the mounting surface at intervals of approximately 200mm (7.8in.) and use end anchors where appropriate. Component and connection management: Avoid changing components as this may affect the suitability of the equipment for use in hazardous areas. Ensure that all external connections are securely fastened by screws, slide latches, threaded connectors, etc.
Troubleshooting and maintenance: The 1794 – OB8 module outputs are not fused and it is recommended that they are protected externally by a SAN – O MQ4 – 800mA fuse. In the event of a module fault, for the 1794-OB8EP module, the fault can be reset by pressing the fault reset button on the front of the module, toggling the output reset bit (Write 1, Bit 08), or cycling the backplane power.

Manual Overview and the FLEX I/O System Manual Content and Purpose: Designed to guide the user through the use of the FLEX I/O analogue modules, covering installation, programming, and troubleshooting, this manual is intended for users who are able to operate Allen-Bradley programmable controllers and understand block transfer programming. The manual describes the FLEX I/O system components and the types of analogue modules that work together through adapters, terminal blocks and I/O modules, which are available in a variety of types to suit different applications. The FLEX I/O system consists of adapters, terminal blocks and I/O modules. Adapters provide internal logic power for multiple I/O modules; terminal blocks are used for wiring two- or three-wire devices; and I/O modules contain bus interfaces and circuits to perform specific functions.
Analogue Module Installation Prepare for installation: Calculate the power requirements of each module and ensure that the total current does not exceed 10A, otherwise a separate power supply is required. Confirm that the product complies with the EU directive, pay attention to static electricity protection during installation, and avoid removing or replacing the terminal blocks under charged conditions. Installation steps: Installation includes mounting the terminal block (DIN rail or panel/wall mounting available), mounting the analogue module to the terminal block (note the key switch position and the Flexbus connector status), and connecting the wiring (wiring varies between modules and terminal blocks). Once the module is mounted, the green power indicator shows whether the module is powered on or not.
Module Programming: The module communicates with the processor via a bi-directional block transfer. Configuration Block Transfer Write (BTW) is used to set up the module functions and Block Transfer Read (BTR) is used to get the module information. The manual gives programming examples for the PLC-3, PLC-5 and PLC-2 processors, emphasising the need to pay attention to the order in which the modules are powered up, the creation of data files and the monitoring of status bits. The analogue data format is 12-bit resolution, left-justified to a 16-bit field, with the highest bit being a sign bit.
Module Configuration and Data Reading Configuration method: When using the Remote I/O Adapter, module functions such as input/output range selection, safety status value selection, etc. are configured via block transfer write commands. The input channels can be configured with various voltage or current ranges and the output modules can be set with safety status values. Data reading: Transfer module status and data to processor data table through block transfer read command. Read/write words and bit/word descriptions are different for different modules, which need to be operated according to specific modules.
DeviceNet Communication and Mapping Communication structure: The DeviceNet Manager software is used to configure the FLEX I/O DeviceNet adapter and related modules. In the polled I/O structure, output data is received in module order, and input data is received first in the adapter status word and then in module order. Data Mapping and Default Values: It introduces the data mapping methods of different analogue modules in DeviceNet, as well as the default values and real-time size settings of the modules. The default values are assigned by the adapter when the system is first powered up and there are no previous stored settings, and the I/O data size can be adjusted according to the requirements.
