Parameters
Parameters of the AI 8xU/I HS
When you assign the module parameters in STEP 7, you use various parameters to specify
the module properties. The following table lists the configurable parameters. 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
When assigning parameters in the user program, use the WRREC instruction to transfer the
parameters to the module by means of data records; refer to the section Parameter
assignment and structure of the parameter data records (Page 38).
The following parameter settings are possible:
