Example
In this example we are using the Schneider PM500 power meter with the following
Modbus table layout:
We are interested in the current, voltage and power values which we read in one block
starting at register 768 with a count of 37 registers. In addition we like to read the energy
counters which we read using a second Modbus transaction from start address 870 and a
count of 8 registers. Because the PM500 document is using 0-based register numbering,
we have to add an offset of 1 to all register addresses before they are entered into the
MBDC-200.
