Event output EV1 allocation
• Selects Event output EV1 from the Event Output Allocation Table below.
For Alarm output, the alarm value is set by
deviation from the SV
(excluding Process alarm), and if the input goes outside the range, the
Alarm output is turned ON (turned OFF for High/Low limit range alarm).
When De-energized action is selected, the output is activated conversely.
Pattern end output turns ON after program control ends.
Loop break alarm output turns ON after detecting actuator trouble (heater
burnout, heater adhesion) or sensor burnout.
‘Output during AT’ turns ON during AT.

Turns ON during AT.
When
001 to 012 (Alarm output) is selected, one alarm can be set to one event output.
When 013 to 015 is selected, each output is common to multiple event outputs.
EV1 alarm hysteresis
• Sets EV1 alarm hysteresis.
• Setting range:
Thermocouple, RTD input: 0.1 to 1000.0
( )
DC voltage, current input: 1 to 10000
(The placement of the decimal point
follows the selection.)
Available when 001 to 012 (Alarm output) is selected in [Event output EV1 allocation].
EV1 alarm delay time
• Sets EV1 alarm action delay time.
When setting time has elapsed after PV enters the alarm output range, the
alarm is activated.
• Setting range:
0 to 10000 seconds
Available when 001 to 012 (Alarm output) is selected in [Event output EV1 allocation].
