Ok, two things need to be addressed here:
1> How do you communicate with your GPS device? If it's using simple serial
commands, then you can use ASCII Object to talk to it.. and hopefully get
the time. If it has a complex protocol, then you will need a driver Object
for it.
2> How can you set the time on your Modbus RTU? I don't know of a way of
doing this directly. May be you can program the RTU to get its time from
one (or more) of the registers. If that can be done, all you need to do
is take the time obtained by the ASCII object.. do some formatting.. and
write it to the register(s).
Hope this helps.

some help to achieve this.
