VC串口通信modbus协议源代码,测试可用。(modbus通信协议)(VC serial communication protocol source code modbus)

DLT645的数据读取,设置串口，后期可能通过数据库读取(read for DLT645 electric)

说明：  很多下位机程序员都有这样的经历，在交付工程的时候对方要求提供源程序，而大多数下位机程序员都知道交出源程序是意味着什么，所以为了保护各位下位机程序员的合法利益.这个工具，伪装过后的源程序可以编译通过。(many lower computer programmers have the same experience that the delivery of the other works on the request source, and most of the next crew to surrender programmers are aware of what it means to the source, Therefore, in order to protect you and lower computer programmer's legitimate interests. this tool, camouflage after the source compile.)

说明：  对松下FP系列PLC通讯串口的调试，了解串口使用的方法(Panasonic FP series PLC serial communications debugging of serial use)
