Assignment of Buffer Memory (BFM)

5.1

Outline of data communication

The interface block FX

2N

-32CCL transfers data between the master station in the CC-Link via the built-in

buffer memory (BFM) backed up by the 16-bit RAM memory. This buffer memory consists of memory dedi-
cated to write and memory dedicated to read. Numbers of #0 to #31 are assigned respectively to each type of
buffer memory.
By writing data from the FX PC to the memory dedicated to write using a TO instruction, the data can be sent
to the master station. The data sent from the master station is read from the memory dedicated to read to the
FX PC using a FROM instruction.
