Cyclic Transmission; Data Flow And Link Device Assignment - Mitsubishi Electric CC-Link IE TSN FR-A8NCG Instruction Manual

NOTE
• Refer to the Instruction Manual (Detailed) of the inverter for functions controllable through the network in each
operation mode.
• The system configuration affects the time period from when the power of the inverter is turned ON until when the
communication between the inverter and the master station is established and either "LINK1" or "LINK2" LED is lit. (It
will take less than 20 seconds.) Design the program so that data communication starts after the master confirms that
communication with the inverter has been established.
6.3

Cyclic transmission

Data communication is available periodically among stations on the same network. Link devices (RX, RY, RWr, and RWw) are
used.
6.3.1

Data flow and link device assignment

 Master and slave stations (except for local stations)
One-to-one communication is possible between the master and slave stations.
The status information of the link devices (RY and RWw) of the master station is output to the external device of the slave
station, and the input status information from the external device of the slave station is stored in the link devices (RX and RWr)
of the master station.
