Parameters

AQ 4xU/I ST parameters
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; see chapter Parameter assignment and
structure of the parameter data record. (Page 32)

* If you enable diagnostics for multiple channels, you will receive an alarm surge on failure of the supply voltage because
each enabled channel will detect this fault. You can prevent this message burst by assigning the diagnostics function to
one channel only.
** You can set the effective range of the diagnostics for each channel in the user program with data records 64 to 67.
