Data Address

The PM1200 power meter supports the transfer of whole block and also of

individual data values (two registers are used for storing single data value).

 In the transfer of individual data values, it treats two registers as an object

with the starting address (e.g., 3900) considered as the object name. This

enables you to transfer required data values for energy management.

 In the transfer of the whole block, it basically treats each block as an object

with the starting address (e.g.,3000) considered as the object name. This

enables fast block transfers, since energy management usually requires a

block of related readings for the same point of time. This method also

eliminates time-skew within readings of that block.

 The device address, block start address, number of registers, must be

configured to suit the power meter. You must also make the related

SCADA settings for polling priority, logging, and viewing the data. Refer

your SCADA software instructions to learn how to do this.

Individual Parameter Address

 Function Code: 03 Read

 No scaling required

 Read as block or individual parameters
