ModbusRTU Serial extended register addresses
« on: December 23, 2014, 11:43:45 AM »
The modbusRTU device I am working with has some registers in extended address range that I would like to access.

0x6000 to 0x615D
0x7000 to 0x71A8

Does the AdvancedHMIDrivers ModbusRTUCom have a way to access this register address range?

Thanks!

You can give it a try by using address 424576

The first digit is used to interpret the function code and the rest is to determine to offset.
