3.6.3 Parameter "Behaviour after I-port short circuit"

Festo P.BE-CPX-CTEL-EN en 1205NH
Through the parameter "Behaviour after I-port short circuit",
the status of supply voltage can be established for an I-port
device after elimination of a short circuit in an I-port connect-
ing cable.
After the short circuit is eliminated, the power supply for the
corresponding device can
– remain switched off (setting "Leave switched-off") or
– be automatically switched on again (setting "switch on
again").
The parameter "Behaviour after I-port short circuit" is em-
bedded as bit 7 in parameter 8. The remaining 7 bits are as-
signed otherwise (see table Tab. 3/1).
When the parameter for changing of the setting is overwrit-
ten, the content of the bits 6...0 can be any desired. Only bit 7
is evaluated for parameterisation.
With access via FMT or MMI, the parameter can be selected
and changed separately. In this way, the parameters "I/O
mode" and "I/O length" can only be read.
Parameter information
The setting is made through bit 7 of parameter 8 (relative
address 7).
