Hi there!
Is there a way to make use of timestamps with deltaV Modbus - either EIOC or VIM2 modules?
We are designing a system to interface DeltaV VIM2 card to a gateway device (GE Multilin G100) via Modbus TCP and we would like to include timestamped data as part of the Modbus protocol.
I know that it is not standard to include timestamps with Modbus but I have come across some example systems that use spare 32 bit registers, for example the Emerson Smart Wireless 1420 Gateway which supports DeltaV).
The reason for this is that the gateway implements IEC 60870-5-101 protocol which uses timestamping for digital signals.
For example, if we send a digital feedback signal (e.g. breaker state open) from DeltaV via modbus, we want to include the timestamp data too.
Any suggestions or ideas would be appreciated!
Thanks
