Chapter layout
Topical structure of this chapter:
1. Chapter overview of which modules are available and described here
2. Overview of essential module properties
3. Steps in selecting and commissioning the digital module
4. General information, i.e. global data applicable to all digital modules (parameter
assignment and diagnostics, for example)
5. Module-specific information (properties, connection and block diagrams, technical data
and special features of the module):
a) for digital input modules
b) for digital output modules
c) for relay output modules
d) for digital IO modules
Installation and wiring
For information on installation and wiring, refer to the S7-300, CPU 31xC, and CPU 31x

Further information
The structure of parameter sets (data records 0, 1 and 128) is described in the system data
section of the appendix. You must be familiar with this structure if you want to modify module
parameters in the STEP 7 user program.
The structure of diagnostic data (data records 0 and 1) is described in the system data
section of the appendix. You must be familiar with this structure if you want to analyze
diagnostics data of the modules in the STEP 7 user program.
