REPLACEMENT OF THE MELSECNET/10 (REMOTE I/O NETWORK)
5.2 Gradually replacing A series remote I/O stations with Q series remote
I/O stations
Use the existing A/AnS/QnA/QnAS series master stations without any change, and gradually replace
the existing remote I/O stations with Q series stations by each station.
For network, MELSECNET/10 can be continuously used by utilizing Q series MELSECNET/H modules
in MELSECNET/10 mode, and thus Q series remote I/O stations can be used together with remaining A/
AnS/QnA/QnAS remote I/O stations.
