【Abstract】 The paper offers the approach to design the program for realizing the communication between OMRON programmable controller and the upper-position processor by VC++6.0, and provides the approach to realize the communication between the computer and the PLC with RS232 tandem communication port. The scheme has been success- fully applied to the variable frequency control to the vibration mill.更多还原
