So bottom line, Modbus require YOU to know what the device it, then find a paper/PDF document from the manufacturer which explains that (for example) data number #73 must be divided by 320, then multiplied by 100.0 to produce a power "amperage" reading. Literally, if you do NOT have a manual, you CANNOT use a Modbus device effectively.

Ensure that the controllers communication parameters are modified in Modbus protocol and at different addresses. In this example, the master is set to an address of 1 and the slave to 2. The number of bits is set to 8, indicating that we will be using Modbus RTU mode. If this had been set to 7, then we would be using Modbus-ASCII mode. The only other default modified was to increase the
