Delta Electronics DTE instruction sheet RS-485 Communication, How to Mount & DIN Rail Size

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.

LRC Check:

Sum up the contents from “machine address” to “data content”, e.g. H01 + H03 + H10 + H00 + H00 + H02 = H16. Obtain 2’scomplement H EA.

CRC (Cyclical Redundancy Check) is obtained by the following steps:

unsigned int reg_crc = 0xffff; i = 0;

while (length--)

{reg_crc ^= RTUData[i];

i++;

for (j = 0; j < 8; j++)
{	if (reg_crc & 0x01)	reg_crc = (reg_crc >> 1) ^ 0xA001;
}	else	reg_crc = reg_crc >> 1;

}

return(reg_crc);
