CI867K01 ABB 3BSE043660R1, AC800M, Modbus TCP Interface

Description:

CI867K01 3BSE043660R1 is a Modbus TCP Interface, manufactured by ABB.
The CI867/TP867 module facilitates communication between an AC 800M controller and external Ethernet devices employing the Modbus TCP protocol, a widely adopted open industry standard renowned for its user-friendly nature. This protocol, functioning at the application layer of the OSI model (level 7), merges the simplicity of MODBUS RTU with the ubiquity of Ethernet and the universal networking standard TCP, operating on a request-response basis and offering functionalities defined by function codes.

Integrated within the CI867 expansion unit are crucial components: CEX-Bus logic for seamless integration, a communication interface tailored for Modbus TCP exchanges, and a DC/DC converter that ensures power supply compatibility by converting the +24 V input from the CEX-Bus to the necessary voltage levels. To establish network connectivity, the Ethernet cable must be routed through an Ethernet switch, linking the device to the broader network infrastructure.

Key attributes and advantages of the CI867 include:
- Redundancy & Hot Swapping: It supports redundant configurations and enables hot swapping, enhancing system reliability and maintenance flexibility.
- Dual Channel Ethernet: Boasting dual Ethernet channels, Channel 1 operates in full duplex mode at a swift 100 Mbps, while Channel 2 functions in half duplex at 10 Mbps. This versatility accommodates diverse network speed requirements.
- Master-Slave Versatility: The unit is capable of acting both as a master and a slave, broadening its applicability in various network setups.
- Scalability: Each CI867 unit can manage up to 70 slave devices and 8 master devices collectively across its two channels, underscoring its capacity to support complex networks with multiple connected devices.
