th
slave device. The data type of energy is
dward. Each parameter takes 2 bits, and each bit takes 2 bytes. AcuRev 1200 series meters’
total real energy addresses are 900H, 901H. Total real energy tariff 1 addresses are 902H,
903H. Total real energy tariff 2 address are 904H, 905H.
Table 5-4 Query Frame of Reading Energy
Response
The slave device anwsers the master device's query. The response frame contains
slave device address, function code, data quantity and CRC check.
Table 5-5 is an example response of reading Total Real Energy (1.27kwh), Total Real
Energy tariff 2 (1.00kwh), Total Real Energy tariff 2 (0.27kwh). (when the energy data is
transmitting, real value= communication value/100).
