Alarm Outputs Section 3-9
PV Change Rate Alarm The change width can be found for PV input values in any set period. Differ-
ences with previous values in each set period are calculated, and an alarm is
output if the result exceeds the alarm value. The PV rate of change calculation
period can be set in units of 60 ms.
If a positive value is set for the alarm value, the PV will operate as a change
rate alarm in the rising direction. If a negative value is set, the PV will operate
as a change rate alarm in the falling direction.
Precaution
If a shorter PV rate of change calculation period is set, outputs set for the PV
change rate alarm function may repeatedly turn ON and OFF for a short
period of time. It is therefore recommended that the PV change rate alarm be
used with the alarm latch turned ON.
SP Alarms When Remote
SP Is Used
RSP Absolute Upper Limit and RSP Absolute Lower Limit parameters were
added for the E5AN-H and E5EN-H (with remote SP input). These parame-
ters are used for a remote SP regardless of whether the SP mode is set to
Remote SP or Local SP Mode.
