2. Modbus规约
Modbus是问答式规约，在铁芯接地项目中将串口接收的Modbus报文转成CDT规约通过网口发给其它厂家
Modbus的数据帧和串口、网口的接收处理代码 Modbus
校验和算法

void
GetCRC(
byte
[] message,
ref
byte
[] CRC)
2 {
3 // Function expects a modbus message of any length as well as a 2 byte CRC array in which to
4 // return the CRC values:
5
6 ushort CRCFull = 0xFFFF ;
7 byte CRCHigh = 0xFF , CRCLow = 0xFF ;
8 char CRCLSB;
9
10 for ( int i = 0 ; i < (message.Length) - 2 ; i ++ )
11 {
12 CRCFull = ( ushort )(CRCFull ^ message[i]);
13
14 for ( int j = 0 ; j < 8 ; j ++ )
15 {
16 CRCLSB = ( char )(CRCFull & 0x0001 );
17 CRCFull = ( ushort )((CRCFull >> 1 ) & 0x7FFF );
18
19 if (CRCLSB == 1 )
20 CRCFull = ( ushort )(CRCFull ^ 0xA001 );
21 }
22 }
23 CRC[ 1 ] = CRCHigh = ( byte )((CRCFull >> 8 ) & 0xFF );
24 CRC[ 0 ] = CRCLow = ( byte )(CRCFull & 0xFF );
25 }
2 {
3 // Function expects a modbus message of any length as well as a 2 byte CRC array in which to
4 // return the CRC values:
5
6 ushort CRCFull = 0xFFFF ;
7 byte CRCHigh = 0xFF , CRCLow = 0xFF ;
8 char CRCLSB;
9
10 for ( int i = 0 ; i < (message.Length) - 2 ; i ++ )
11 {
12 CRCFull = ( ushort )(CRCFull ^ message[i]);
13
14 for ( int j = 0 ; j < 8 ; j ++ )
15 {
16 CRCLSB = ( char )(CRCFull & 0x0001 );
17 CRCFull = ( ushort )((CRCFull >> 1 ) & 0x7FFF );
18
19 if (CRCLSB == 1 )
20 CRCFull = ( ushort )(CRCFull ^ 0xA001 );
21 }
22 }
23 CRC[ 1 ] = CRCHigh = ( byte )((CRCFull >> 8 ) & 0xFF );
24 CRC[ 0 ] = CRCLow = ( byte )(CRCFull & 0xFF );
25 }
3.CDT规约
通过网络接收开关的报文进行处理。也是问答式，只有召唤才回复数据。下面这是从Modbus到CDT转换项目中的代码
4.仿IEC101规约
在IEC101规约里地址域是两个字节我们项目需要使用了6个字节，同时扩展了数据域
P101 字段

我在电力行业的公司中做软件开发，这些是工作中用到的规约和部分代码，希望对做电力软件的朋友有点借鉴意义，代码都不完整还请见谅。
工作将近4年，感觉到不学习新技术会被公司炒掉，不积累行业背景和经验会被社会炒掉，所以建了一个QQ群 19060470 来讨论行业解决方案，还请各行各业的软件同行们能够加入。
