Time Sync Via modbus

Hi,

I’m trying to determine whether it’s possible to set the time of a SNAP-PAC-R1 from a Modbus register.

We have a Rockwell controller that will be time-synchronised with a time server. This controller will then pass the time to the Opto PLC.

Is it possible to set the time on the Opto PLC by reading a Modbus register?

Thanks,
Dominic

Hello, you can find the Date and Time MMP addresses from Pac Manager under System and then convert the MMP addresses to Modbus using the Tools/Modbus Calculator in Pac Manager

thank you, and for that would i could then write to those addresses setting the time?

Would i to send everything individually in floats ie minutes seconds etc

Per the OptoMMP protocol guide date and time is in the format YY-MM-DD HH:MM:SS.00. The guide has more details about what each address holds and how to format data to write / how data is formatted when reading.
