The total connection requirements for a 1768 CompactLogix system include both local and
remote (distributed) connections. Tallying local controller connections is not an issue
because the controllers supports all the connections required for the maximum number of
I/O modules and 1769-SDN scanners in one system. It is important to tally remote
(distributed) connections via the EtherNet/IP network because each 1768-ENBT scanner
supports 48 connections.
