FX2N-16CCL-M CC-Link System Master Block
Specification 4
4-12
4.6.3
I/O signals to PLC
This section describes I/O signals used to control the master block.
The signals used to control the master block are assigned to the buffer memory (BFM#A
H
and
BFM#B
H
) built in the FX
2N
-16CCL-M.
The buffer memory of the same number works differently between the time of read (when the
FROM instruction is used) and the time of write (when the TO instruction is used) as shown in
the table below.
The system automatically changes over these functions in accordance with the instruction
(FROM or TO).
The table below shows also the assignment of I/O numbers adopted in the A/QnA/Q Series
master module as reference. These I/O numbers are available only in the A/QnA/Q Series, and
are not available in the CC-Link system for the FX Series. When making a program, make sure
to specify bits of the buffer memory.
