ONFIGURATION
Combined logic functions
The functions are implemented through the
combination of up to four control variables.
Any control variable can be selected. The states
Z1 to Z4 are assigned to the control variables in
descending order of the control variables (see list
on the right).
Example:
The process value is to be selected via a logic
input and the state of one limit comparator.
This results in the following assignment:
Z1 - logic input 1
Z2 - limit comparator 1
Setpoint/process value switching
Setpoint Process value Z2 Z1
Setpoint 1
Setpoint of system status
External setpoint configured controller process value
of controller channel 0 0
Setpoint 2 Analog input 2 0 1
Setpoint 3 Analog input 3 1 0
Setpoint 4 Analog input 4 1 1
0 = contact open / OFF
1 = contact closed / ON
If switching between two setpoints or two process values is required, only one logic function
has to be configured.
If more than two logic functions are configured to setpoint switching or process value
switching, only the first two (see list “Control variable - State”) are significant.
