Parameters of AI 8xU/I HF
The AI 8xU/I HF is usually already integrated in the hardware catalog of STEP 7 (TIA Portal).
In this case, STEP 7 (TIA Portal) checks the configured properties for plausibility during
configuration.
However, you can also assign parameters to the module by means of a GSD file and the
configuration software of any provider. The module does not check the validity of the
configured properties until after the configuration has been loaded.
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 (Page 50).
The following parameter settings for the channels are possible:
