计算CRC校验和,可以计算modbus规约/CDT规约/DISA规约/DF1规约/DNP规约/1801等规约的校验和.-and CRC calculation, modbus connection can be calculated Statute / CDT Statute / DISA Statute / DF1 Statute / DNP Statute / 18 01 of the Statute, such as checksum.

根据CDT规约的要求，实现CRC校验。本CRC校验程序采用非查表法，为大家提供一种思考编写CRC校验程序的思路。-According to the requirements of the statute CDT achieve CRC. The CRC checking of program non-look-up table, provide a way of thinking the idea of ​ ​ writing programs CRC checksum.

CDT规约中CRC校验码的生成方法，标准cdt通讯源码,具有循环上送和下行控制功能CDTSender,c#写的CDT规约解析 并 打包 发送程序，经过测试可以使用等等， 总有一个源程序能帮上
