8.2 Process of High-speed Link Send/Receive Data
For the application example of High-speed link, the master station “0” and slave stations “1” and “2”
(MPL-RY2A, MPL-D24A) are to share data with each other.
Setting is as follows;
1) The master station “0” transmits 2 bytes of D00200 data to the slave station “1”.
2) 4 bytes of the data received from the station “2” are saved on D00201, D00202.
