Main Features & Advantages
- Dual‑channel galvanically‑isolated PROFIBUS‑DP master interface: Two independent channels enable line‑redundant fieldbus to avoid single‑point communication failure for critical loops.
- DP‑V1 full support: Handles cyclic real‑time I/O data exchange plus acyclic parameter access, diagnostic reading and HART tunnelling for smart field instruments.
- System‑level redundancy capability: Supports 1+1 hot‑standby master redundancy when paired with BC810 CEX‑Bus redundancy and redundant AC 800M CPU, achieving uninterrupted field‑bus operation during module fault or maintenance.
- High‑speed flexible baud‑rate range: Covers all standard PROFIBUS speeds from low‑speed long‑distance to maximum 12 Mbit/s for high‑performance machine control segments.
- Seamless integration with System 800xA: Fully configured via Control Builder M, supports rich diagnostic information visible in operator workplace for fast fault localization.
- Hot‑swap capability: Module can be replaced during system running without powering down the whole rack (applies to properly redundant architectures).
- Wide third‑party device compatibility: Works with PROFIBUS‑DP‑compliant remote I/O, variable‑speed drives, valve positioners, transmitters and other DP‑V0/V1 slave devices from multi‑vendors.
Application Scenarios
- Process industry DCS control: Oil & gas, chemical, pulp‑and‑paper, power plant auxiliary control, water‑wastewater treatment plants using ABB System 800xA AC 800M controllers.
- Redundant critical control systems: Safety‑related non‑SIL control loops requiring field‑bus communication resilience, where bus line or master redundancy is mandatory.
- Migration & retrofit projects: Legacy ABB 800xA system spare‑part replacement for existing PROFIBUS‑DP installations (not recommended for brand‑new green‑field sites due to RoHS‑2 limitation)ABB Group.
- Mixed‑vendor automation integration: Connect Siemens ET200 remote I/O, third‑party VFDs, DP‑based smart instruments to ABB AC 800M controller platform.
- Manufacturing & heavy‑industry automation: Metallurgy, cement, mining plant control with distributed PROFIBUS‑DP field I/O clusters.

FAQ – Frequently Asked Questions
Q1: Can CI854AK01 (3BSE030220R1) be used for new‑project construction?
A: Not officially recommended. This classic part is non‑RoHS‑2 compliant and designated for spare‑part repair and upgrade of existing systems commissioned before July 22 2017. For green‑field installations, select CI854BK01 (3BSE069449R1) insteadABB Group.
Q2: Does CI854A work as PROFIBUS‑DP slave?
A: No. CI854A is strictly a DP‑V0/V1 master‑only interface. It cannot act as a PROFIBUS slave device on another DP segment.
Q3: BF bus‑fault LED lights red, no slave communication. What are common root causes?
A: 1) Missing, wrong‑version or corrupted GSD file imported in Control Builder M; 2) Incorrect bus termination (110 Ω resistors must be fitted at both physical ends of PROFIBUS‑DP cable); 3) Baud‑rate mismatch between master and slaves; 4) Damaged bus cable, loose DB‑9 connectors or wrong station address assignment for DP slaves.
Q4: What hardware is required to implement master‑redundancy?
A: Two modules, BC810 CEX‑Bus redundancy module, and redundant AC 800M CPU pair. Line‑redundancy only requires one with both DP channels wired to field devices.
Q5: Can I hot‑swap module during system online?
A: Hot‑swap is physically supported for rack‑plug‑in modules. In non‑redundant configurations, hot‑removal will cause total PROFIBUS‑DP communication loss. Only under redundant master setup can swapping one module keep field‑bus operation continuous.
Q6: How many PROFIBUS‑DP slaves can one handle?
A: Theoretical maximum 124 slaves for the whole module. Each physical DP cable segment allows maximum 32 nodes; use PROFIBUS repeaters for multi‑segment expansion to reach full slave count.
Q7: Will run with AC 800M controller firmware newer than 6.0?
A: is legacy hardware. Compatibility should be verified before firmware upgrade. For latest System 800xA versions, CI854B is the preferred PROFIBUS‑DP master solutionABB Group.
Q8: Why does intermittent communication happen on PROFIBUS‑DP network?
A: Main triggers: poor cable shielding grounding, wrong bus termination, baud‑rate too high for actual cable length, EMI interference near power cables, or degraded connectors. Follow PROFIBUS installation guidelines for cable routing and earthing practice.
