Besides cancelling P632 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.
