Hi all, I use Omron PLC. I don't know the Real Time Clock. Where I can find this information. email@example.com
For C200H series PLCs, look at words AR18 through 21. To set the clock on the C200HX PLCs: 1. Set PLC in Program mode. 2. Set bit AR21.14. This stops the clock and allows you to write to it. 3. Enter the desired values: AR18 (Seconds in low byte, minutes in high byte), AR19 (Hours in low byte, day of month in high byte), AR20 (Month in low byte, 2 digit year in high byte), AR21 (Day of week in low byte) 4. Set AR21.15. This sets the new values in the internal clock and resumes the clock operation. >Where I can find this information. Omron PLC manuals can be viewed online at http://oeiweb.omron.com/oei/ . Select Support, then Technical Manuals, then Programmable Controllers.
Some of the Omron PLC's like the CQM1 and CQM1-A require a seperate clock module card to be installed before access the clock funtcion as described above.
Cleanliness is next to impossible.
