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