Chapter 6 High-speed Link Service
6-16
4) Function Block for High Speed Link
At XGR and XGI, there is function block to deal with the reception data. And at XGK,
there is no function block. So apply the program acting as Function Block. Refer to
Ch6.7
.
5) TX/RX method by using sequence number is standard algorithm. If there is special
pattern according to user application, the user can’t use this.
(2)
In case XGK(I) is transmission mode and XGR is reception mode
1) TRX setting
Make the two modules of XGK(I) send same data by same setting. At this time,
sequence number is not necessary. Take the data entering to the Master as input data
and considering the network error, use the STATE FLAG as condition to take the input
data. If STATE FLAG is OFF, copy the data of Standby to Master by SYNC instruction
and take it as input data
Note
(1) For block setting, A-Side and B-Side is used in same manner. So station number of TX is
different, take the double of block.
