Error handling

When quitting the COMMIS (Commissioning) menu, the unit checks which input
signals are connected:
• A sensor error message is displayed when one of these signals is subsequently
missing:
−
"Xx ---" Signal missing (e.g. in the event of a cable break).
−
"Xx ooo" Short-circuit (only applicable to passive signals).
• Outputs are set to predetermined values when the function blocks are unable to
run calculations due to a missing input signal (see function block section "Error
handling").
Changing the identifier for an inputs after the configuration for the other function
blocks is completed may cause certain functions for these blocks to become
inactive as otherwise they would have to operate on invalid units.
