*Warning: The command procedure listed here can cause undesirable results to your product if applied incorrectly. Before sending any commands, verify all commands and parameters are correct. If you have any doubts, contact Technical Support for guidance.*
The following instructions use Modbus Tester to read and write the commands. Other Modbus polling software's can also be used.
Step 1: Identify the Command Number and necessary Parameters
- Open the Modbus Register List
- Navigate to the Commands tab and locate the desired command
- Write down the Command Number and the Parameters
In this example, the user wants to send the Reset All Energies command to the PM5560. As shown in Table 1, the Reset All Energies command number is 2020. This command also has 1 parameter, the command semaphore. This information will be necessary in Step 3.
| Table 1: Modbus Register List Excerpt |
| Command Name | Command Number | Command Tag | Parameters |
| Reset All Energies | 2020 | C_RESET_ALL_ENERGIES | (1) Command Semaphore |
Step 2: Get the Semaphore
- In Modbus Tester, set the Data Type to "Holding Register (R03 / W16)".
- The Command Semaphore is stored in Modbus register 5680. Therefore, set the Starting Register to 5680.
- Set # or Registers to be 1.
- Then Click on Read once.
Note: During this time no other communication with the meter should run in the background. Otherwise it may cause in error.
Note: Only perform the reading operation once. Doing more than once will cause in error. If by mistake the operation is performed more than one time then it is advised to try to do the operation again after 4 min.
