Control interface for measuring modes
Parameter LOAD_VAL (bytes 0 to 3) has two different meanings:
● You set bit L_PREPAR to define the LOAD_VAL parameter as a low limit.
● You set bit C_DOPARA bit in byte 0 to define the reaction at output DO0.

Irrelevant 0 0 No comparison
Irrelevant 0 1 Out of limits
Irrelevant 1 0 Below the low limit
Irrelevant 1 1 Above the high limit
