1、通过DLL与PLC通信,基于ppi协议。
2、DLL文件名:S7_200_PPI.dll
3、串口,连接线为西门子PC-PPI电缆或自己焊接
4、S7-200 PLC 默认参数即可
5、默认一次最多读取100个VB字节或50个VW字,通过修改相关参数,可以读取更多
6、为了简化程序,仅提供V区操作,实际应用中足够了
7、操作VW字时,地址应为偶数-1, by the DLL to communicate with the PLC, based on the ppi agreements. DLL file name: S7_200_PPI.dll 3, serial cable for Siemens PC-PPI cable or welding 4, S7-200 PLC default parameter to 5, the default up to read 100 VB bytes or 50 VW word, by modifying the relevant parameters, you can read more 6 V region of operation, in order to simplify procedures, only in the practical application of sufficient 7 operating VW words, the address should be an even number
