1793-OB16PS - I/O Module - ALLEN BRADLEY

FLEX Integra is a small, modular I/O system for distributed applications that performs all the functions of rack I/O. The FLEX Integra

The system contains the following components shown below:

• adapter/power supply – powers the internal logic of up to eight I/O Modules

• I/O module with integrated wiring terminals – contains the bus interface and circuitry necessary to perform specific functions related to your application and connection terminals to connect the wiring

FLEX Integra analog input, output, and combiner modules are block transfer modules that interface analog signals to any Allen-Bradley programmable controllers with block transfer capability. Block transfer programming moves the input from the module's memory to a designated area in the processor data table, and output data words from a designated area in the processor data table to the processor's memory. module. Block transfer programming also moves the processor configuration words data table into module memory.

The adapter/power supply transfers data to the module (block-transfer write) and from the module (block-transfer read) using BTW and BTR instructions in your ladder diagram program. These instructions allow the adapter to obtain the input values and status of the module and allow you to send output values and establish the operating mode of the module. Figure 1.1 describes the communication process.
