Ethernet-based Interfaces & Protocols

• 10/100/1000 Mbps industrial Ethernet ports with auto-negotiation and redundancy support (MRP, PRP/HSR)
• Full compliance with mainstream industrial protocols: PROFINET IO Controller/Device, Modbus TCP, OPC UA/DA, Ethernet/IP Adapter/Scanner
• Support for standard TCP/IP suite (TCP, UDP, ICMP, DHCP, DNS) for network management and data transmission
• HART IP protocol support for integrating smart field instruments into Ethernet networks
• BACnet IP protocol compatibility for building automation system integration

     Serial Communication

• Configurable RS-232/RS-485 serial ports (1–2 embedded ports, expandable up to 8 ports via modules)
• Support for Modbus RTU, ASCII, and custom serial protocols for legacy device connection
• Data transmission rates ranging from 300 bps to 115.2 kbps, with hardware flow control (RTS/CTS) support
• Isolated serial interfaces to enhance anti-interference capability in harsh industrial environments

     Interfaces for ABB Devices

• Native compatibility with ABB AC 800xA distributed control system for seamless integration into ABB's automation ecosystem
• Dedicated interfaces for ABB drives (ACS series), soft starters (PST series) and motor starters, enabling direct parameter configuration and control
• Support for ABB's proprietary communication protocols to ensure high-speed data exchange between AC 800M and ABB field devices
• Unified diagnostics and maintenance functions for ABB device networks, reducing system management complexity

     Interfaces for Legacy System Communication

• PROFIBUS DP/V1 master/slave expansion modules for connecting to legacy PROFIBUS-based automation systems
• Serial gateway modules to convert between serial protocols (RS-232/RS-485) and Ethernet protocols, enabling legacy device access via modern networks
• Support for DDE (Dynamic Data Exchange) and OPC DA for data integration with traditional SCADA systems

• Custom protocol development tools to meet the communication requirements of non-standard legacy equipment

AC 800M Communication interfacesCI856

S100 I/O communication is realized in AC 800M by communication interface CI856, which is connected to the CEX-Bus through a base plate. The baseplate, TP856, houses a ribbon connector connecting to bus extender boards in S100 I/O racks and provides a simple DIN-rail mounting. Up to five S100 I/O racks can be connected to one CI856 where each I/O rack can hold up to 20 I/O boards.

The CI856 is powered by the processor unit, via the CEX-Bus, and therefore does not require any additional external power source

AC 800M Communication interfacesCI857

INSUM integration into AC 800M supports higher functionality integration, multidrop configurations, time distribution and time stamping in the switchgear, and utilizes standard Ethernet technology for longer communication distances. The speed of this solution is typically 500 ms for one closed loop (indication from one motor until operation of another, assuming 250 ms cycle time in control execution).

AC 800M controllers access the INSUM functions through function blocks in the INSUM Communication Library. The CI857 is powered by the processor unit, via the CEX-Bus, and therefore does not require any additional external power source.

AC 800M Communication interfacesCI858

The DriveBus protocol is used to communicate with ABB Drives and ABB Special I/O units. DriveBus is connected to the controller via a CI858 communication interface unit. The DriveBus interface is used for communication between ABB Drives and AC 800M controller.

The DriveBus communication is especially designed for sectional drive applications for ABB rolling mill drive systems, and ABB paper machine control systems. The CI858 is powered by the processor unit, via the CEX-Bus, and therefore does not require any additional external power source.
