2 Instruction Descriptions
4
Use the LimitAlarmDvStbySeq_REAL instruction to output upper/lower deviation alarms with a
standby sequence for the deviation between the set point and the process temperature.
5
Perform an output as a safety measure if an error occurs in the LimitAlarmDvStbySeq_REAL
instruction or if an upper/lower deviation alarm occurs.
6
Perform temperature control with the PIDAT instruction.
7
Use the TimeProportionalOut instruction to output the manipulated variable as a time-propor-
tional value to the heating device.
