Abstract
Introduces the CRC arithmetic that is usually used in communication.When the CRC is used in subminiature PLC,the software of CRC is designed in a different way.The paper discusses the software design of CRC.The design is used successfully in the modbus communication between Siemens S7-200 PLC and Delta frequency inverters.
