Sharp JW-21MN manual 62

-Set the receiving area for save memory function within the range of the link area.

0 ≤ a1 ≤ Total number of bytes of relay link area -h1

0 ≤ an ≤ Total number of bytes of relay link area -hn

0 ≤ b1 ≤ Total number of bytes of register link area -i1

0 ≤ bn ≤ Total number of bytes of register link area -in

-Number of offset bytes can be set exceeding the number of sending bytes of the master station. a1, an ‡ c0 and b1, bn ‡ d0

-Setting example of top address f1/fn/g1/gn

When the setting value of the module No. switch is "2," f1/fn is ｺ1200, g1/gn is 29000.

(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 station 01 and the data link (save memory function) to slave station 02.
