7.5 Method for maintaining existing addresses when replacing MELSECNET/MINI(-S3) with CC-Link

7.5 Method for maintaining existing addresses when replacing MELSECNET/MINI(-S3)
with CC-Link
The existing MELSECNET/MINI(-S3) and the CC-Link differ in the number of occupied points per
station: the former has 8 points per station, and the latter 32 points.
When the existing and new modules differ in the number of occupied points or the number of the
existing modules differs from that of the new modules, it is necessary to change the addresses to be
used in the sequence program. However, the existing addresses can be maintained by transferring
input/output data using the existing address of each station (module) by FROM/TO instructions without
using the CC-Link auto refresh function.
● Replacement example
(1) Number of occupied points per station
The number of occupied points per existing MELSECNET/MINI(-S3) station is 8. A module with
more than 8 points requires more than one station.
