Below is an example of CC-Link configuration settings made by GX Developer software and how
memory is allocated. This configuration has 3 sets of H FC3000 controllers connected with 4 occupied
stations / 8 extended cyclic cycles. (I/O 896 Points, Message 72 Words)

In the case of the first AFC3000 System (1) (shown in the table above), the PLC program is set
so that
when the 888th (378h) bit (“Initial Data Processing Request”) in the (CC-Link Reserved) system area (X
area) is turned “ON”, the output at the 888th (378h) bit (“Initial Data Processing Complete”) of the system area
(Y area) is set “ON”.
Since the X/Y starting address of (System 1) is configured to start at X100 and Y100, this must be
added to the addresses and therefore (100h+378h) 478h is specified for the X area and the Y area as shown in
the PLC Logic diagram below to enable Station 1’s link.
(If the handshake is successful, 47B (100h + 378h + 3h) turns ON)
For Station 2’s link, the starting address (X/Y480) is added to the 888th (378h) bit for that station
which is address (480h + 378h) X/Y7F8.
(If the handshake is successful, 7FB (480h + 378h + 3h) turns ON)
For Station 3’s link, the starting address (X/Y800) is added to the 888th (378h) bit for that station
which is address X/YB78.
(If the handshake is successful, B7B (800h + 378h + 3h) turns ON)
