Setting data Description Set by Data type
(n1)
(First I/O No. of the target CPU)/16
Value to specify actually is the following.
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.
User 16-bit binary
(S1) Start device of the self CPU where control data is stored. User Word
(S2)
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
CPU outside the range in the PLC CPU that executes this instruction, by
setting it by a character sequence " ".

Complete devices
(D2+0): Device which make turn on for one scan at accept completion of
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.)
