8.6.3 Non−equivalence monitoring
By the non−equivalence monitoring you check two digital inputs each with regard to an
unequal input level. If the input level is the same for both digital inputs, an error is reported.
For non−equivalence monitoring, sensors with a normally open contact (no) and a normally
closed contact (nc) are suitable. Both contacts have to be switched at the same time.
There are four non−equivalence monitoring functions, which can be set via C0402. Each
monitoring function can exactly check two digital inputs with regard to each other.
In C0403 you set the error deceleration times.
