The vendor’s Series 90-30 programmable logic controller family has been enhanced with a new Ethernet Network Interface Unit (ENIU).
This high-performance communications module enables users to connect Series 90-30 I/O over Ethernet to a master controller through a single point of connect, saving configuration time and reducing component count. Users can connect the programmer anywhere on the I/O network and monitor, configure and troubleshoot any ENIU or the master controller. The Series 90-30 ENIU features a built-in Ethernet switch with two (one IP address) 10/100Mbit ports (RJ-45), allowing the user to daisy chain to the next ENIU without the need for expensive external switches. The ENIU can be expanded with up to seven local I/O expansion bases with a total of 70 I/O modules per drop.
