Omron CJ - PROGRAMMING MANUAL 12-2009 - Setting the Scheduled Interrupt to Units of 0.1 Ms

322
Using a Scheduled Interrupt as a High-precision Timer (CJ1-H-R and CJ1M Only) Section 6-5
Example:
1,2,3... 1. Input interrupt task starts when the built-in input bit turns ON.
2. Output bit A turns ON in the input interrupt task, and the MSKS(690) in-
struction is executed to perform a scheduled interrupt reset start.
3. After a fixed interval, the scheduled interrupt task starts, and output bit A
in the scheduled interrupt task turns OFF, and the MSKS(690) instruction
is executed to prohibit a scheduled interrupt.
6-5-1 Setting the Scheduled Interrupt to Units of 0.1 ms
The scheduled interrupt time is set using the PLC Setup’s scheduled interrupt
unit time setting and the MSKS(690) instruction.
With CJ1-H-R and CJ1M CPU Units, the scheduled interrupt time can be set
in units of 0.1 ms.
• CJ1H-R CPU Units: When the units are set to 0.1 ms, the scheduled
interrupt time can be set between 0.2 ms and 999.9 ms.
• CJ1M CPU Units: When the units are set to 0.1 ms, the scheduled inter-
rupt time can be set between 0.5 ms and 999.9 ms.
PLC Setup
When using the CX-Programmer, make the settings on the Timings Tab Page.
