Limit value combination (single-channel modules only)
200 A0534-30.0 HBM: public MGCplus
Example:
Task: The range between 10 kN and 20 kN will be monitored and assessed
as "OK". The assessment will be represented in the display by "OK" or
"NOK".
Solution: Limit switch 1 monitors the 10kN limit, limit switch 2 monitors the
20 kN limit. The two are combined together with "AND". The result of the
combination controls the output of limit switch 3.
