DI 32x24VDC HF parameters
When you assign the module parameters in STEP 7, you use various parameters to specify
the module properties. The parameters that can be set depend on whether you use the
module in standard mode or in counter mode. You will find the parameters in section
Parameters DI mode (Page 16) or section Parameters of the Counting mode (Page 18). The
effective range of the configurable parameters depends on the type of configuration. The
following configurations are possible:
● Central operation with a S7-1500 CPU
● Distributed operation on PROFINET IO in an ET 200MP system
● Distributed operation on PROFIBUS DP in an ET 200MP system
For parameter reassignment in the user program, the parameters are transferred to the
module with the WRREC instruction (parameter reassignment in RUN) using data records;
see section Parameter assignment and structure of the parameter data records (Page 47).
