The dedicated instruction (REMTO/REMFR) to read/write the buffer memory of intelligent device station takes
a few scans before the instruction is completed. The result of dedicated instruction is not synchronous with the
result of I/O signals operation.
When controlling the output signal after reading/writing buffer memory, set the interlock so that the I/O signals
are controlled after the completion device of dedicated instruction turns on.
For details on the dedicated instructions (REMTO/REMFR), refer to the following.
