- An example of register link area map for the setting of the data link (the save memory function) to
slave station 01 and 03 and data link (the standard function) to slave station 02.
(3) When the master station and slave stations are all JW-21MN's and both data link (the stan-
dard function) and data link (the save memory function) are set among slave stations.
Set signs below by the parameters of the master station (page 11-5, 6) and the module No. switch
of the JW-21MN (page 11-2).
- An example of a relay link area map for the setting of the data link (standard function) for slave
