• Page 36: Abnormal Responses

  For detail of CRC16 parity arithmetic, please refer to Section 4 . 8.2.4. Abnormal Responses If a Modbus master device sends a non-effective command to a SPM33 or attempts to read a non-effective holding register, an exception response will be generated.

  8.4. Calculating the CRC-16 Error Check Field This section describes the procedure for obtaining the CRC-16 error check field. A packet can be considered as a continuous, serial stream of binary data (0, 1). The 16-bit checksum is obtained by multiplying the serial data stream by 216 (10000000000000000) and then dividing it by the generator polynomial x +1, which can be expressed as a binary data 11000000000000101.
