PXU MODBUS REGISTER TABLE
09/04/2015
The following is an example of the necessary query and corresponding response for holding register 2. In this example register 2 is the decimal value 123.
Query: 01 03 00 01 00 01 D5 CA
Response: 01 03 02 00 7B F8 67
Notes:
1. The PXU registers can be read as holding (4x) or input (3x) registers.
2. The PXU should not be powered down while parameters are being changed. Doing so may result in an in-complete write to the non-volatile memory and produce
checksum errors.
