Indications
Measures
H’0001
PV_MIN_MAX_ALM
It occurs when the set PV is beyond the min./max. PV.
H’0002
PID_SCANTIME_ALM
It occurs when PID operation cycle is too short. It is
desirable to set PID operation cycle longer than PLC scan
time.
H’0003
PID_dPV_WARN
It occurs when the PV change of PID cycle exceeds PV
change limit.
H’0004
PID_dMV_WARN
It occurs when the PV cycle MV change exceeds MV
change limit.
H’0005
PID_MV_MAX_WARN
It occurs when the calculated MV of PID cycle exceeds the
max. MV.
H’0006
PID_MV_MIN_WARN
It occurs when the calculated MV of PID cycle is smaller
than the min. MV
