Description
1. Basic Overview
Model: CI546
Material No.: 3BSE012610R1
Type: PROFIBUS DP Master Communication Card
Applicable Systems: ABB AC 400 / Advant Master / 800xA DCS
Function: Acting as a DP master, it manages the entire PROFIBUS DP bus and connects multiple DP slaves (such as remote I/O, frequency converters and instruments). It is not a slave card.
II. Key Facts (Highlights)
❌ Not an Ethernet module
Does not support TCP/IP protocol, and cannot be connected to switches or Ethernet cables.
Interface: Dual RJ45 ports, operating on ABB proprietary AF100 Twisted Pair Bus (TWP).
❌ Not PROFIBUS DP or PROFINET
CI546 and CI854 are PROFIBUS DP modules; CI869 only adopts AF100 protocol with a baud rate of 500 kbps.
✅ Actual Application
Enables AC800M to communicate with legacy ABB systems, including AC160, Advant Master and Connectivity Server.
Mainly used for DCS upgrade, renovation and compatibility between new and old systems.
III. Technical Specifications
Protocol: AF100 (TWP, Twisted Pair), Baud Rate: 500 kbps
Interface: Dual RJ45 ports for AF100 bus, supporting redundant bus and redundant interfaces
Power Supply: 24 VDC (Powered via backplane CEX-Bus)
Dimensions: 127.5 × 185 × 59 mm; Weight: Approx. 0.6 kg
Operating Temperature: -20°C … +60°C; Ingress Protection: IP20
Features: Hot-swap capability, redundant communication, bus diagnostics
