4. This function will consume 3 ~ 5 seconds more when you switch on DTE.
RS-485 Communication
1.DTE supports baud rates 2,400/4,800/9,600/19,200/38,400/57,600/115,200 bps and does not support communication format 7, N, 1/8, E, 2/8, O, 2. Communication protocol = Modbus ASCII or RTU.
2.Function codes: H03 = read maximum 8 words in the register; H06 = write 1 word into the register.
3.Address and contents: Every parameter has 2 communication addresses. One is numbered by the function of the parameter, and the other is by the order of channel (as shown in the table below).

Error Codes:
The error codes can be read from address H1000 ~ H1007. When the input operation is in normal status, H1000 ~ H1007 are for input values. When input error occurs (except for stable status and input exceeding the range), DTE will read error codes in H8001 ~ H8002.
H1000 | Error description |
|
|
H8001 | EEPROM cannot be written in. |
H8002 | Input sensor is not connected. |
H8003 | Group INB is not connected. |
