Does anyone know how to synchronise the time between these two?
I had thought that the HMI could write a LINT (time/date in microsecronds) to the PLC, but now I find that the 5x70 range can't properly handle LINT types.
So the only way I know now, is;
This seems an awfully long winded workaround. Anyone know a better way?

So the only way I know now, is;
- Add 7 Data input fields on the HMI (Y,M,D,H,M,S,uS)
- Add a 'WRITE PLC TIME' button
- Use an SSV to set the PLC time
- Compile a DATA string and a TIME string in the PLC
- Have the HMI read these strings and set its own time/date with the HMI system tags
