Alarms
Alarm types: Upper limit, lower limit, differential upper limit, differential lower
limit, upper limit on rate-of-change, lower limit on rate-of-change,
delay upper limit, delay lower limit
Number of settings: Four levels per channel
ON/OFF can be set for each channel and level
Alarm setting range: DC voltage, TC, RTD, DI, strain, pulse, resistance, linear scaling,
differential between channels, remote RJC
Hysteresis: Alarm OFF value arbitrarily set
Rate-of-change calculation interval of rate-of-change alarms:
Upper limit on rate-of-change alarm: 1 to 32 times the
measurement interval
Lower limit on rate-of-change alarm: 1 to 32 times the
measurement interval
Number of alarm outputs:
10 to 60 outputs (10 points per DO module)
Output mode: Energize/De-energize, AND/OR, Hold/Non-hold
Alarm ACK: If set to hold using the alarm status or relay output Hold/Non-hold,
the hold status is cleared.
Alarm output update interval:
100 ms (not synchronized with the measurement interval)
Delay alarm: Delay time:
1 to 3600 s, common setting for delay upper and lower limits.
Set the delay time to an integer multiple of the measurement
or MATH interval. If it is not, the delay time is increased to an
integer multiple of the measurement or MATH interval. If the
delay time is shorter than the measurement or MATH interval,
the delay time is set to the measurement or MATH interval.
Operation at power failure:
After the power supply recovers, the alarm detection behavior
is reset, and new alarm detection is started.
Math start action:
The alarm detection behavior on the MATH channel is reset,
and new alarm detection is started.
Reflash alarm: If multiple alarms are assigned to an output relay and the
second alarm occurs while the first relay is activated, the relay is
deactivated once and activated again.
