Hi Robert,
Thanks for your previuos message.
The data in the PLC that I am going to communicate with Proview is not in a contiguous register numbers. Some data is located at 600H, 900H, 1200H, etc.
It can either be used FC03 or FC04. i tried to configure two Modbus module with different starting register numbers, but it did not work.
When I tried to combine FC03 and FC04, the query for FC04 was not correct. It requested from slave 4 regs. instead of 2 regs.
Is it possible to fetch the data located in a non-contiguous register mapping in PLC?.
