Description: 1. Prodave for pc and s7 series plc data link communications between the toolbox. Its essence is a user called "w95_s7.dll" and other library functions to resolve between the PLC and the PC data exchange and data processing problems. Hardware requirements: CPU22x, PC/PPI programming cable, with a COM port of the PC. This is probably the most simple configuration, it is easy to achieve the purpose of the experiment. Here Prodave need to install the software, so long as "w95_s7.dll" copy files to your program can go to the appropriate directory.
2. Communication Settings: Open "Control Panel" in "Set PG/PC interface" option, in the "Application access point" list box select "S7ONLINE (STEP7) PC/PPI Cable", in its properties within the "timeout" You can set big point here is set to 100ms, "baud rate" is set to 9.6kbps (because of my pc/ppi cable made in China does not support multi-master station), "address" to 0.
