• Number of receiving bytes of slave station (h1 to hn, i1 to in)
Select self-setting or “same as number of sending bytes (c1 to cn, d1 to dn)” according to parameter
(007720 to 007723) of slave station.
• Number of offset bytes can be set exceeding the number of sending bytes of the master station.

(3) When the master station and slave stations are all JW-20CM and both data link (the
standard function) and data link ( V5 memory capacity save function) are set among
slave stations.
Set signs below by the parameters of the master station (page 9·22, 33 and 34).
• An example of a relay link area map for the setting of the data link (standard function) for slave
station 01 and the data link (memory capacity save function) to slave station 02.
