Behaviour in case of malfunctions in operation
If there is a malfunction on an I-port during operation, e.g. broken cable, etc., this will be indicated by
flashing or illumination of the display LED (X1 ... X4) of the corresponding I-port on the CTEL master
module.
The behaviour of the affected device is dependent on the device type.
Moreover, additional diagnostic information of the module is available and can be called up both via the
fieldbus used as well as via the Festo Maintenance Tool (CPX-FMT) or the operator unit (CPX-MMI).

4.4.1
Start of the CPX terminal with system setting “Stored parameters”
If the start setting “Stored parameters” is configured in the system settings of the CPX
terminal instead of “Standard parameters”, the current assignment of the I/O address
space of all modules remains permanently stored in the CPX terminal.
Particularly if the CTEL master module is operated in the automatic configuration, the following must
be observed:
In case of a change of the I/O assignment of the I-ports (e.g. through connection/disconnection of
devices or wire break in the I-port connecting cable) in combination with a restart of the CPX terminal,
the error “Incorrect I/O length” is reported, since the currently existing I/O configuration of the CTEL
master differs from the configuration stored in the CPX terminal.
