Interval Timer Interrupts
The CPM1A has one interval timer. The interval timer shuts down the regular program irrelevant of the point in the cycle once the time
is up, and immediately executes an interrupt processing program. Interval timers are used in the following two modes.
Item
One-shot mode Scheduled interrupt mode
Operation An interrupt is executed only once when the time is up. Interrupts are executed repeatedly at fixed periods.
Setting time 0.5 ms to 319,968 ms (0.1-ms units)
Normal program

Application Example:
Computing the Sheet Speed
The number of pulse inputs is computed in the in-
terrupt mode at a fixed time to calculate the speed.

Analog Setting
The CPM1A contains two analog setting controls that can be used for a broad range of analog timer and counter settings. Turning the
setting control stores values of 0 to 200 (BCD data) in the SR area.
Analog setting Storage area Setting value (BCD)
Analog setting 0 SR 250
0000 to 0200
Analog setting 1 SR 251
Application Example:
Tact Operation Control of Conveyor Lines
A conveyor can be stopped temporarily as required for assembly
processes. When the timer function and limit switches are used in a
combination, conveyors can be stopped for a fixed time or can be run
at a constant speed for a fixed distance. Fine adjustment of the stop-
ping time can be easily done by using the analog setting controls.
