(5) Support for functions dedicated for data communication with
programmable controllers
MX Component provides the functions necessary for data communication with
programmable controllers, including functions for opening/closing communication
lines and reading/writing devices.
Multi-function communication programs can thus easily be developed with MX
Component.
