How to obtain the serial number through modbus for a PM5100 and PM5300 meters

From the modbus register list. Refer to FAQ link below. Will need to look at registers 129, 130 and 132 for the full serial number.

Register 129 is the plant code and 130 and 131 is the rest of the serial number digits.

Plant code for PM5100 is 34 and plant code for PM5300 is 54.

Example:

In order to calculate the serial number digits the formula below can be used:

(Register 130 * 65536) + Register 131

Instance above is (915*65536) + 39296 = 60004736

The rest of the serial number digits is always 10 digits long, if it does not display 10, need to add zeros at the start of the string of digits:

Instance above 0060004736

Adding the plant code of 34 will give the full serial number:

Full serial number 340060004736

The tool used above is Modbus Tester. See link below to the tool.
