Purpose of the 3170-PDP
The 3170-PDP 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 3170-PDP 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 3170-PDP
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.
