摘要:
The PLC has a user configurable protocol port attached thereto. Briefly stated, at the PLC communication port or as a result of a user program or I/O event, a special flag bit may be set which thereby allows the communication port to be activated. This is done by the flag bit causing an interrupt to occur in the PLC user program which allows a user to communicate with a user specified protocol scheme rather than the normal communication/programming protocol when this special bit is not set.
