I was suprised LabVIEW didn t had the CRC32. So I made it, http://en.wikipedia....edundancy_check, http://www.ietf.org/rfc/rfc1952.txt. It can take a array of U32, one element of U32 or a string. When needed I can create more CRC checks, CRC8, CRC16, etc... but CRC32 is the most used one I readed.

Labview的详细开发指南,包括:双精度数据不适于相等比较(内置函数);顺序结构是“结构”吗?;到底什么是“节点”;XY GRAPH的输入参数形式 ;整型数据类型和内存映射;状态机的基本概念 ;状态机的基本类型顺序结构 ;状态机的基本类型之标准状态机 ;事件结构中的TIMEOUT进行数据采集合适吗 ;全局变量、移位寄存器和功能型全局变量的性能比较等。(Labview detailed development guidelines, including: double precision data is not suitable for equality comparison (built-in function) sequential structure is " structural" it? In the end what is " node" input parameters of the form XY GRAPH integer data types and memory mapping basic concept of the state machine basic types of sequential structure of the state machine basic types of state machine standard state machine event structure The TIMEOUT data collection suitable for you global variables, shift registers and functional performance comparison of global variables and so on.)

优点:1,PPI协议通讯速度快,比OPC ,PCAccess,Modbus 快4-5倍左右。(就这一条优点就足了,呵呵) 2,PLC端无需编写任何通讯程序。 3,可以直接对PLC进行,RUN STOP等操作。 4,本程序全部采用LABVIEW底层程序框图,没用调用任何的DLL ,API等。这点对你学习还是修改程序功能都很有帮助,方便。 (Advantages: 1, PPI protocol communications faster than OPC, PCAccess, Modbus about 4-5 times faster. (On which an advantage on the feet, huh, huh) 2, PLC-side without writing any communication program. 3, can be carried out directly on the PLC, RUN STOP operation. 4, the procedure used in all LABVIEW underlying the block diagram, useless to call any DLL, API, etc. This is for you to learn or modify the program features are very helpful and convenient.)
