You will find the tables of the measuring ranges as well as overflow, overrange, etc., in the
section Representation of analog values (Page 38).
4.2 Parameters
Parameters of the AI 4xI 2-/4-wire ST
Specify the module properties with the various parameters in the course of your STEP 7
configuration. 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 an ET 200SP CPU
● Distributed operation on PROFINET IO in an ET 200SP system
● Distributed operation with PROFIBUS DP in an ET 200SP system
When assigning parameters in the user program, use the "WRREC" instruction to transfer
the parameters to the module using the data records; refer to the section Parameter
assignment and structure of the parameter data record (Page 33).
