Programming restrictions when operating SM 331; AI 8 x TC with PROFIBUS masters which only
support DPV0.
When operating the SM 331; AI 8 xTC analog input module on an ET 200M PROFIBUS
slave system and the PROFIBUS master is not an S7 master, certain parameters are not
permitted. Non-S7 masters do not support hardware interrupts. All parameters associated
with these functions are disabled for this reason. This includes hardware interrupt enable,
hardware restrictions and end of cycle interrupt enable. All other parameters are allowed.
