The 1794-APB is a FLEX I/O adapter that interacts with the FLEX

I/O backplane and any PROFIBUS DP master/scanner controller on

a PROFIBUS DP network.

The 1794-APB module is a slave device to the DP master/scanner,

and is a master controller of the FLEX I/O system where it is

installed.

The I/O data exchange occurs as follows: Output data is sent from

the DP master/scanner controller across the PROFIBUS DP network

to the 1794-APB adapter. The adapter then automatically transfers

the data across the FLEX I/O backplane to the output modules.

Inputs from the input modules are collected by the FLEX I/O adapter

via the backplane and sent across the PROFIBUS DP network to the

DP master/scanner controller.
