ABB CI867AK01 Modbus TCP Interface Overview

The ABB CI867AK01 is a communication interface for AC 800M controllers. This package includes the CI867A module and the TP867 baseplate. The ABB CI867AK01 uses Modbus TCP protocol for industrial networking. Modbus TCP combines Modbus RTU with standard Ethernet and TCP protocols. This is an application-layer messaging protocol at OSI model level 7. The CI867AK01 connects an AC 800M controller to external Ethernet devices. The article number for this complete package is 3BSE043660R1.
