Could we give the CurrentTime to Relay using the Control Fuction(getCurrentTime()) with Modbus TCP/IP communication?

[interelec]

We would like to give the CurrentTime cyclically(Time Stamping) to Relay using the Control Function(getCurrentTime()) with Modbus TCP/IP communication.

1. Is it possible to use the Global Scipt for time stamping?
2. If it is possible, Is it stable for Network that connect with 50~100 Relays in each 13 Substations.

If you have other solutions aobut this question, please suggest to me.

thanks.

What does this question have to do with the user days?
If you post your question in another forum part it will reach more forum users.

Thread moved to HowTo section.
I guess the Question & Answers sections name in the User Days Forum is a bit misleading.

Hello,

the Modbus-driver does not support a synchronization of PLCs as it is possible with other drivers, e.g. the S7-driver.
Do you want to write the time to a dp-element with an output address or how shall the information be send to the device?


P.S.: Your posting in the Questions & Answers section I have removed as it was the wrong place.

1. It is possible to use a script to cyclically pass the current time to modbus devices.
2. It should be stable, but there could be some time between the write action and when the time arrives at the device(s). Especially with modbus gateways.
