Maximum Bus Capacity: Supports up to 125 PROFIBUS DP slave stations

Isolation Performance: Provides galvanic isolation between controller backplane and PROFIBUS field bus to enhance anti-interference capability

Diagnostic Features: Equipped with onboard LED indicators for power status, running state, bus communication and network faults; supports PROFIBUS bus fault diagnosis and real-time slave device status monitoring

Installation Method: Plug-in design for direct installation on AC 800M controller slots

Relative Humidity: 5% ~ 95%, non-condensing environment

EMC Standard: Compliant with IEC industrial electromagnetic compatibility specifications

Core Function: Acts as a PROFIBUS DP master station interface, enabling data communication between AC800M controllers and DP slave devices such as remote I/O modules, variable frequency drives and field transmitters

Wiring Instructions for ABB CI522AK14 (3BSE018460R1)

Required Tools: PROFIBUS-certified shielded twisted-pair cable, 9-pin D-sub PROFIBUS connector, screwdriver, lockout-tagout equipment

Pre-wiring Preparation

Carry out lockout-tagout procedures on the AC 800M controller rack power supply. Verify the module model CI522AK14 (3BSE018460R1). This plug-in PROFIBUS DP master interface module is designed for the AC 800M controller. It is powered directly by the rack backplane, so no separate external power wiring is needed. Only PROFIBUS standard shielded twisted-pair cable shall be used for the DP bus.

Module Installation and Backplane Connection

Insert the CI522AK14 into the assigned slot of the AC 800M controller rack, and press it steadily until the latch engages and locks. Ensure reliable contact between the module connector and rack backplane. The backplane supplies operating power and establishes the internal communication link with the controller.

9-pin D-sub Connector Pin Assignment (Female Port on CI522AK14)

Pin 1: Not used

Pin 2: Not used

Pin 3: RxD/TxD-P (Data Line B, positive signal, typically red conductor)

Pin 4: CNTR-P, repeater control signal, optional and generally not applied

Pin 5: DGND, data reference ground

Pin 6: VP, +5 VDC supply for bus terminator

Pin 7: Not used

Pin 8: RxD/TxD-N (Data Line A, negative signal, typically green conductor)

Pin 9: Not used

Shield: Cable shield bonded to the metal shell of the D-sub connector

PROFIBUS Bus Wiring Requirements

A daisy-chain topology shall be adopted. Connect the DP port of CI522AK14 to the first DP slave device, and continue daisy-chaining to subsequent slave nodes. Star topology is prohibited. The 120 Ω bus terminator switch shall only be enabled on the two physical ends of the PROFIBUS segment; all intermediate nodes must keep the terminator disabled.

Shield and Grounding Requirements

Separate PROFIBUS signal cables from high-power cables to minimize electromagnetic interference. The cable shield shall be secured to the connector shell at each DP plug. Apply single-point grounding to the protective earth inside the control cabinet. Double-ended grounding of the shield is forbidden to eliminate ground loop currents.

Final Inspection and Power-on

Reconfirm that Data Line A and Data Line B are not crossed, and check for short circuits between signal wires and ground. Validate the correct setting of terminator switches. Release lockout-tagout and energize the rack. Observe the RUN and BUS LED indicators of the module after power is applied.
