5.4 PLC I/O Expansion Application

PLC

I-7188XB(D)

7000 series modules

COM1: RS-232

COM2: RS-485

Most PLCs contain a Man Machine Interface that was originally
designed for MMI applications. The I-7188XB(D) can use this interface
to construct a bridge between a PLC and the 7000 series modules.

The I-7188XB(D) can directly read/write from/to the internal memory of
the PLC, meaning that the PLC can access the 7000 series input
modules as follows:

The I-7188XB(D) sends a command to the 7000 series input

modules

The I-7188XB(D) writes this data to the internal memory of the

PLC

The PLC accesses this data from its internal memory

The PLC can control the 7000 series output modules as follows:

The PLC writes data to its internal memory
The I-7188XB(D) reads the output data from the memory of the

PLC

The I-7188XB(D) sends a command to its 7000 output modules
