Fig. 3-55: Enabling or disabling a device function.
Besides cancelling P634 functions from the configuration, it is also possible to
disable protection via a function parameter or binary signal inputs. Protection
can only be disabled or enabled through binary signal inputs if the
MAIN: Disable protect. EXT and MAIN: Enable protect. EXT functions are
both configured. When neither or only one of the two functions is configured, the
condition is interpreted as “Protection externally enabled”. If the triggering
signals of the binary signal inputs are implausible – i.e. both are at logic level =
“1” – then the last plausible state remains stored in memory.
If the protection is disabled via a binary signal input that is configured for
MAIN: Disable protect. EXT, the signal MAIN: Blocked/faulty is not issued.
