6.2 HS link Tx/Rx Data Processing
HS link application will be described below with the example where FDEnet I/F modules of the stations No.0 and No.1 are to
send and receive the data between each other.
Its setting sequence is as follows;
(a) The station No.0 transmits M0000 data of 10 words to No.0 block.
(b) The data received by the station No.1 is saved on M0010.
(c) The station No.1 receives M0000 data of 10 words from the station No.0 to save on M0100.
(d) M0110 data of 10 words is transmitted to No.1 block.
There are 64 blocks for Tx data and 128 blocks for Rx data in the HS link parameters. The block number can be set 0~63 for
transmission or receiving. The Tx side needs only to decide which data to read and which block to send to without setting the
correspondent station No. when transmitting the data
