- Abnormal situations the power meter records the type and time of the alarm occurred in the register 38
- Based on start stop status for the 10 types of alarm settings address location 0x1f 0xb7 under 38
- Below informing the reason why the main station experienced abnormal situation 38
- Location 0x400 0x483 the types of alarms and their descriptions are as follows 38
- Messages of abnormal operations 38
- Under abnormal communications the power meter can send out messages via modbus codes shown 38

- Parity none odd even 40
- Stop bit 1 40
- 1 modbus rtu mode is adopted with modbus master sending out the request in which the function 41
- Are shown in the example below 41
- Code uses 0x03 to request response from slave to correspond to values in modbus address in 41
- Format of modbus communication 41
- Function code modbus name description 41
- High byte low byte high byte low byte 41
- Low word high word 41
- Master 41
- Modbus communication 41
- Modbus communication protocols 41
- Packet format of ieee754 is used for the address of floating point numbers that corresponds to the 41
- Register values found in table 7 using 2 s complement packet format the format are as follows 41
- Request 41
- Response 41
- Response modbus slave responds to the values of modbus address in the master request the 41
- The packet formats for the address of integers that corresponds to the register values found in table 7 41
- X03 read holding registers read the contents of read location 41
- X06 write single holding registers preset the contents of written location 41
- X10 write multiple holding registers preset the contents of written location 41
- Ct setting register address 0x000e on the power meter modbus slave slave address 0x1 the 42
- Example 42
- For modbus master such as plc or data collector it uses modbus protocol to get the value of 42
- Master request 42
- Register value is 1000 42
- Slave response 42
- The packet format for request sent out by modbus master plc or data collector is as follows 42
- The packet format for response responded by modbus slave power meter is as follows 42
- After receiving response from the power meter modbus master acquires the value of currents from the primary side current transformer register address 0x000e which is 1000 43
- Should modbus slave power meter receive an abnormal request the format of the abnormal packet responded is as follows refer to chapter 9 for the abnormal codes 43
- Slave response 43
- Appendix 44
- Appendix 1 selecting accessories 44
- Current transformer 44
- For the current transformer the model with a closer maximal current on the primary side should be select ed according to the maximal current actually input for example when the maximal current input is 700 a dct s261c can be selected 44
- Notes on selecting a current transformer 44
- Should input current exceed rated current tolerated by the meter 44
- Specifications the power meter needs to be used together with a current 44
- Transformer ct users can select a suitable ct according to the table below 44
- Wire over length on the secondary side of the current transformer causes decrease in accuracy 44
