How to send command to control the digital output using Modbus protocol to PM5350.

How can we help you today?

For PM5350 meter, to energize Digital output, you should use command code 6003; to de-energize digital
output, you should use command code 6002.

Here is an example for writing register to "De-energize Digital Output DO2" via using Modbus tester (or PMC Modbus).

Select Data Type: W16 (to write Multiple registers);

Select Starting Register: 5250;

Select # of Resister: 3;

Write: 405250 ->6002; 405251 ->0; 405252->2

Press "Write" button.

Please keep in mind that the command write must be done in a block write and it will not work if you write each register individually!
