64bit data type in modbus

64bit data type in modbus

In my case, IEDs should time synchronized by zenon. The IED type is P123 from AREVA and its protocol is Modbus RTU. Zenon dose not support data type of time register in P123 because it consists from 4 word (64bit).
Please find its data sheet as attachment.
How can I write pc time to these registers in Modbus RTU protocol by zenon?
Do you have plan for supporting LREAL or ULINT datatypes in future for zenon modbus driver?
thanks
