Cautions for initial program of master channel when the link system i s a combination of remote 1/0 system and local
system.
0
In regards t o the assignment of link on master channel side of initial program, the link range i s assigned consecutive-
ly, beginning with the address next to the 1/0 address used for the master channel. In the above example, the
number of total link points is 320 and the
1/0
addresses used for the master channel are
00
-
6F. Therefore, link
addresses are X70
-
Y 1
F.
0
When the KJ71P3 i s used for the local channel, the link address begins with the address after the 1/0 address of
KJ71 P3. In the above example, the link address of local channel 3 begins with X/Y
80.
0
When the KOJlP i s used, the link address on remote channel side begins with X/YlOO and the link addresses on the
local channel side are X/YlOO
