APPENDICES
(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.

For details of the functions, refer to the programming manual for MX Component.
(6) Collecting data on Excel without programming
Using MX Component and MX Sheet (SWnD5C-SHEET-E) allows users to
collect programmable controller device data on Excel with only simple setting
and without any programming.
