Set Points

Each OIT can have up to 16 set points. For each set point, the OIT monitors the value in a

PLC register. When that value exceeds the specified low or high limit, the specified

stored screen is displayed. For more information, refer to the Set Points section in

CHAPTER 4: PLC Register Monitors.

Timer Event

(OIT3250, OIT4450, OIT5400 only)

The OIT3250, OIT4450, and OIT5400 include a real-time clock that can be used by the OIT

as a timer. This allows the OIT to display a stored screen and set a coil in the PLC at a

particular time during a particular day of the week, or daily. For example, a timer event could

be configured to display screen 5 and set PLC coil CR100 every Monday at 10:30 a.m. Up to

16 timer events can be programmed. Timer events are checked by the OIT once every minute.

NOTE:If an alarm screen is active when the timer event activates, the screen associated with

the timer event will be lost unless the screen stack is enabled. For more information on

the screen stack, refer to the Screen Stack section in this chapter.
