DM6100/DM6300 Digital Meter Chapter 6 Data Communication 03/2011

Transcription

1 Data Address The DM6300 digital meters support the transfer of whole block and also of individual data values (two registers are us for storing single data values). In the transfer of individual data values, it treats two registers as an object, with the starting address (e.g., 3000) consider as the object name. This enables you to transfer requir data values for energy management. In the transfer of a whole block, it treats each block as an object with the starting address (e.g., 1000) consider as the object name. This enables fast block transfers, since energy management usually requires a block of relat readings for the same point of time. This method also eliminates time-skew within readings of that block. The device address, block start address, and the number of registers, must be configur to match the digital meter. You must also make the relat SCADA settings for polling priority, logging, and viewing data. Refer to the SCADA software instructions to learn how to do this.

The SCADA software must support register blocks consisting of different data s (integers and floats) to transfer the whole block. Each Modbus register size is 16 bits. All DM6300 digital meters readings are 32 bits. Therefore, each DM6300 digital meters reading occupies two consecutive Modbus registers. For example, PF total parameter absolute address is It occupies both 3055 and 3056 Modbus registers. Address configuration: All addresses are in decimal. Some SCADA software supports Modbus register address instead of absolute register address. In this case add to the above address and use it. For example PF total parameter absolute address is Modbus address can be ( ). All digital meter addresses should be set between 1 and 247. All digital meters should have uniform communication settings like Baud rate, parity, and stop bit. Use communication diagnostic mode display page in the digital meter to analyze the status of the communication.
