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), SCD8000/8100 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.

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);
