An output device is recognised, but the CTEL master module is configured for operation as a pure
input module.
The system can still be operated. Corresponding to the setting for the relevant I-Port, either an I-Port
configuration error is reported (with setting “Expect device”) or no error message is issued (with set
ting “Use existing device”).
The reserved address space for input data is completely assigned; all input bits are set to the value “0”.
Write access to the outputs of the connected device is not possible.

Behaviour with error at the PL/PS supply
If the CTEL master module recognises a short circuit or overload at an I-Port on one of the related
power supply cables PS or PL, the I-Port involved is always switched off completely (PS and PL off ).
Behaviour after elimination of the error can be set via the parameter “Behaviour after I-Port short cir
cuit” (
