Chapter 5. FUNCTIONS
■
Events 1 to 3, Time events 1 to 5
In event configuration data setup, they are used after setting the
event type, event standby, hysteresis and ON delay time. A total of
four event types which are PV type events, controller status events,
time events and segment number events are available.
Segment number events can be set by time events 1 to 5 only.
In the constant-value operation mode, the time events 1 to 5 do not
function.

PV type events
• Basic specifications
The next page shows event type PV, deviation, absolute value
deviation, SP, MV and MFB. In the figures, the thick lines show
ON-OFF changes in state. The upper line expresses the ON state,
and the lower line the OFF state.
EV and H stand for event setting value and hysteresis, respec-
tively. Output in the READY state is OFF.
• Event standby
Events function as follows when event standby has been set to ON:
- If the controller is in the
state in the figure when changing
from the READY to the RUN mode and after restoring the
power, operation is the same as when event standby is set to
OFF. The up-facing arrow in the figure indicates a change to
ON, and a down-facing arrow indicates a change to OFF.
- If the controller is outside the
state in the figure when
changing from the READY to the RUN mode and after restor-
ing the power, the state is OFF. After entering the
state, the
up-facing arrow in the figure indicates a change to ON, and a
downfacing arrow indicates a change to OFF.
• Event ON delay
The event No. to apply the delay to and the delay time can be set
regardless of event type. “Delay” functions to turn output ON
when the event is continuously ON for the preset delay time after
the event OFF→ON condition is satisfied.
When event ON delay is combined with event standby, event
standby must first be canceled before event ON delay functions.
