COMMUNICATIONS BETWEEN CPU MODULES
POINT
Remark
One QCPU can concurrently issue up to 32 instructions of "Instructions dedicated
to Motion CPU" and "Multiple CPU transmission dedicated instructions (except for
S(P).GINT)".
Note that multiple instructions are executed in order starting from the first
instruction.
When 33 or more incomplete instructions are identified, an "OPERATION ERROR
(error code: 4107)" occurs.
• For details and availability of the multiple CPU transmission dedicated
instruction, refer to the manual of the Motion CPU.
• The C Controller module has the function which writes/reads device data to/
from the Motion CPU.
For details, refer to the manual of the C Controller module.
