Can the WinPLC handle 10 communication ports simultaneously? What kind of affect will this have on the normal process?
WinPLC can handle a maximum of 10 communication ports simultaneously. Each port is handled by interrupt as it gets data. Each port has a 16-byte buffer. It can therefore handle this kind of simultaneous communications task extremely fast especially at lower bps (e.g. 9600). Of course, as the bps is increased then this takes more and more processing time to keep up with the data that is getting dumped into the buffers. Also, keep in mind that the WinPLC is more like a conventional PC rather than a PLC. Therefore it is very difficult to determine exactly what kind of an effect this will have on your normal process.
