4.3 PID_Compact V1
PID control
Function Manual, 03/2017, A5E35300227-AC
101
Advanced settings V1
Process value monitoring V1
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.
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:
< 10° C and ≥ 0° C FALSE TRUE Automatic mode
