Nodeguard response
Fig. 2/9: Start nodeguard monitoring
The nodeguard monitoring of the CP valve terminal with
CANopen direct link starts when the first nodeguard
telegram is received. This telegram must be cyclically
repeated in the following time:
guardtime x lifetime factor (index 100C x index 100D)
If this time is exceeded, the valves will be switched off
or they will assume the default status.
PLEASE NOTE
The timeout monitoring remains inactive in the CP
valve terminal until the first Nodeguard telegram is re-
ceived. Valves which are switched on remain set
even after loss of communication, bus interruption,
etc.
