Setting data
(First I/O No. of the target CPU)/16
Value to specify actually is the following.
(n1)
CPU No.2: 3E1H, CPU No.3: 3E2H, CPU No.4: 3E3H
(Note): Motion CPU cannot be set as CPU No.1 in the Multiple CPU configuration.
(S1) Start device of the self CPU where control data is stored.
Start device of the target CPU where reading data is stored.
POINT Data can be read from device like a motion register (#) etc. of Motion
(S2)
(D1) Start device of the self CPU which stores the reading data.
Complete devices
(D2+0): Device which make turn on for one scan at accept completion of
(D2) instruction.
(D2+1): Device which make turn on for one scan at accept abnormal completion of
instruction. ("D1+0" also turns on at the abnormal completion.)
