Ethernet I/O Continued

EtherNet/IP (Ethernet Industrial Protocol) is traditional Ethernet combined with an industrial application layer protocol targeted to industrial automation. This application layer protocol is the Control and Information Protocol (CIP). EtherNet/IP was created in an attempt to overcome the shortcomings of traditional IEEE 802.3 Ethernet as applied to the industrial automation world. Acromag offers a variety of options to fit your needs: Ethernet Analog I/O, Ethernet Digital I/O, Ethernet Multi-Function I/O, and Ethernet Switches and Converters.
