Module Data

This section explains how the input/output channels of the TX-I/O modules are
mapped to the SIMATIC S7 input/output addresses.
7.1

General

Every newly added ('plugged') module must be addressed. This procedure is not
similar for all modules. We distinguish between
binary input/output modules and

analog and multistate modules.

The addressing takes place on the module (subslot 1) according to the binary
channel of the module.
The SIMATIC S7 address of a binary input/output is obtained from the
parameterized address of the module plus the offset specified in the table.
Example
Module input address
Channel 4
SIMATIC S7 address
The addressing takes place on the submodule (subslots 2...1) according to the
analog or multistate function.
The SIMATIC S7 address of the analog/multistate input/output is obtained directly
from the subslot address parameterized in the channel.
The offsets specified in the tables are also assigned.
Example
Submodule input address
SIMATIC S7 address
The SIMATIC addresses of the channel process data are given below.
Local override information is indicated separately for each individual TX-I/O
module.
