How to synchronise the internal clock of an HMISTU855 with the RTC (Real Time Clock)of a M258.

Using Modbus Protocol: By using the "Dialog Table Settings" in Vijeo Designer. This DialogTable
is not supported with SoMachine protocol.
 
Using So Machine Protocol: There is no automatic synchronisation. A work-around can be done by writing a
script in Vijeo Designer. In this case, the script (which sets the HMI clock) can be periodic or event triggered.
The PLC RTC time (composed of variables used in the script) is extracted from the GetTime Function
