How to modify energy readings on a Powerlogic meter or move the values from one meter to another

Issue
This procedure explains how to move or transfer the Energy Readings from one meter to another meter. This function is only supported in some of the Powerlogic meters.

Products
Series 2000 Circuit Monitor
Series 3000 Circuit Monitor
Series 4000 Circuit Monitor
Series 800 Power Meter

Cause
A meter is replaced by another meter, a master reset has been run on the meter, or a meter has been cleared by accident. Any of these situations could require the energy readings to be preset. Typically a new meter will start at 0 KWH. This can affect billing if the energy readings are not preset in the meter.

Resolution
The process of reading and writing registers in blocks can be performed using third party software such as Modscan or Modbus Tester. (Modbus Tester can be obtained from article FA180037)
It can also be performed from the front panel of each meter to read and write individual registers. Refer to the reference manual of each meter for information on reading and writing registers.

1. Read the Energy registers from the CM2000, CM3000, CM4000, or PM800 meters to be copied from. Make a note of the readings using Table 1.

2. Read this entire step before beginning. Write the values noted from Step 1 to the appropriate registers 8022 - 8049 in the replacement meter. **Note: You must write the entire 28-register block to the 8022 - 8049 buffer, either as a single-block write or as 28 individual writes. The matching write-to registers are listed in Table 1.

1. Registers 8022 - 8049 coincide with the register order read from 1700 - 1727.
2. Register 8022 - 8049 must be an integer value between -9999 and +9999. If any register contains a value outside that range, the process will abort.
3. The registers in the Series 2000 Circuit Monitor are not in the same sequence as the CM3000/CM4000/PM800.

* Registers are not in sequential order.

3. Next, write the following decimal values to the registers of the replacement meter:

1. 8020 to register 8017
2. 8021 to register 8018
3. 8022 to register 8019
4. 6209 to register 8000

4. Read register 8021 for the status of the process.

1. 0 = the settings completed successfully.
2. 81 = Invalid Command Function (Verify that the 6209 command code was written to register 8000.)
3. 82 = Invalid Parameters (verify that the data range in register 8022 8049 is between -9999 to +9999.)

5. Verify that the values were successfully written by reading register 1700 - 1727 in the replacement meter. Note that the values may start incrementing immediately if the meter has a load.
