ET 200U Distributed I/O Station
EWA 4NEB 812 6087–02b
Each I/O module is assigned an object in the static object list. For I/O mod-
ules with inputs and outputs, the ET 200U(DP Standard/FMS) generates two
objects (one in the input area and one in the output area).
The objects have the object code “Simple–Variable” or “Array”. An array can
also be accessed via a subindex.
The following tables show the structure of the “input” or “output” object for
both the “Simple–Variable” and “Array”. On the following pages, the coding
of I/O modules is described.
