Outline of the Buffer Memory for Communication
The PLC CC-Link master/local unit communicates with the F160 by using the buffer memory in
the unit. Hereafter,
the master unit (master station) is called “M” and
the F160 (remote device station) is called “R” in the explanation.
Since one F160 occupies two stations, station numbers are set as shown below when two or more
F160s are connected. The upper column and lower column show the buffer name and buffer address
(head), respectively. As just described, the addresses allocated to the remote stations in the master
station change according to the station number.
Specified F160s are accessed by using these buffer addresses.
In the application program of the PLC, the buffer memory is accessed by the FROM/TO instruction
at A series.
The following explanations are given on the F160 of station No. 1.
