12. CRC Calculation RTU mode The MODBUS interface also operates in RTU mode and uses CRC for error checking The CRC value is two bytes containing a 16 bit binary value The CRC value is calculated by the transmitting device that appends the CRC to the message The receiving device recalculates the CRC and compares it to the value in the message If the values are not the same the receiver does not process the message The CRC value is calculated according to the following procedure 1 Initialize a 16 bit CRC register to OxFFFF 2 Place the first 8 bit character from the message and place it into a test register 3 Exclusive OR the test character with the CRC register leaving the result in the CRC register 4 The CRC register is shifted one bit toward the least significant bit the least significant bit is saved into a carry register and the most significant bit is zero filled 5 If the old least significant bit was zero go to step 6 if it was one the CRC register is exclusive Ored with Oxa001 Repeat steps 4 and 5 seven times Using each successive character in the message repeat steps 3 through 6 8 The CRC is the value in the CRC register 9 The CRC value is placed into the message in hexadecimal format with the most significant byte going into the first CRC byte and the least significant byte going into the last CRC byte RTU Message Framing E 4 In RTU mode messages start with a silence interval of a
