7.2 Response of the analog input module
Requirement
You can use the PROFIenergy function when you use the internal encoder supply.
Display
The channel status LEDs are not affected by PROFIenergy.
Response to error detection
All channels that are in pause mode on "PE_MODE_PROCEED" report their diagnostic
status as in productive mode.
The following applies for all channels which switch to a different pause mode:
● Encoder supply switch-off upon the start of "pause" does not result in the alarm "Wire
break".
● "Wire break", "Short circuit", "High limit violated" and "Low limit violated" error detection is
not possible during the "pause":
– Alarms for errors already pending before the "pause" are retained.
– After the "pause" is over, the error status is updated and incoming/outgoing errors are
● Hardware interrupts are not signaled.
