Implrmentation multidisplinary PC communication based parrel printer EPP mode
초록
영어
We input and output data using SPP(Standard Printer Port)mode which called printer port when process control module while using existing parallel port. But SPP mode limite input & output data number(out 8 bit, input 5 bit), transfer speed is very slower than ISA method. The advanced method is multidisplinary PC communication method which connecting serial PC communication to RS-232C connector using EPP(Enhanced Parallel Port) mode. we discuss the advanced method of processing a lot of control module using this method.
