| Abstract: | The communication between upper PC and SIMENSE S7-200 PLC is realized by control MSComm of VB under the free port way. The communication was controlled through receive interruption, send break, character interruption, sends the order (XMT) and receives the order (RCV). And PC was used as the host computer, and PLC was as slave PC. The rotational speed PID of the electrical machinery was controlled by control order of PID offered with S7-200, combined import / export the modules to realize the control of analog quantity. |
