Process value monitoring as of V2 (S7-1200, S7-1500) - PID

Configure a warning high and low limit for the process value in the "Process value monitoring" configuration window. If one of the warning limits is exceeded or undershot during operation, a warning will be displayed at the PID_Compact instruction:

• At the InputWarning_H output parameter if the warning high limit has been exceeded

• At the InputWarning_L output parameter if the warning low limit has been undershot

The warning limits must be within the process value high and low limits.

The process value high and low limits will be used if you do not enter values.

Example

Process value high limit = 98 °C; warning high limit = 90 °C

Warning low limit = 10 °C; process value low limit = 0 °C

PID_Compact will respond as follows:

In the output value settings, you can specify the reaction of PID_Compact when the process value high limit or low limit is violated.
