Defining the limit values
The following must be specified for each of the six limit values in order to program the limit
monitoring function:
● Limit monitoring on/off
● Monitored measured variable
● Upper or lower limit violated
● Limit
● Time delay
● Hysteresis
Combining the limit values
Figure 2-1 Device setting "LIMIT LOGIC"
The following operators are available:
● AND
● OR
The placeholder "----" means: This limit value is not combined with any other limit value.
The logic combines limit values 0 to 5 as follows:
(((((opLIM0 opLIM1 LIM1) opLIM2 LIM2) opLIM3 LIM3) opLIM4 LIM4) opLIM5 LIM5)
represents the logic operator AND/OR in the formula
The brackets in the formula show that the AND/OR priority rule does not apply.
The result of the logic operation is the "LIMIT LOGIC".
