Data Link Communication between Master and Slave Stations
The master station has 6 data registers assigned to transmit data to a slave station and 6 data registers assigned to
receive data from a slave station. The quantity of data registers for data link can be selected from 0 through 6 using
WindLDR. The following examples illustrate how data is exchanged between the master and slave stations when 2 or 6
data registers are used for data link communication with each of 31 slave stations.
Example 1: Transmit Data 2 Words and Receive Data 2 Words
