CC-LINK Network Communication
WUME-SCHG1C-4 4-2
4-1 Overview of communication
4-1-1 Communication with master station
Data is exchanged between the communication unit and master station using link devices.
There are four types of link devices: “Remote input RX”, “Remote output RY”, “Remote register
RWr”, and “Remote register RWw”.
The link device values of each are periodically updated by cyclic transmission.
Communication unit functions and link device assignments can be checked using the memory
map.
By accessing a link device that supports memory map, the master station can use the functions
of a communication unit.
