Main LAS role on FF H1: Acts as the segment’s primary scheduler, ensuring deterministic message timing and function block execution.
Redundancy-ready architecture: Often deployed with CI571 as backup; switchover is typically fast and transparent to field devices.
Stable time distribution: Keeps all devices synchronized on 31.25 kbit/s H1, which reduces jitter for tight PID or interlocks.
Diagnostics & alarms: Supports segment health monitoring so technicians quickly see device status, LAS activity, and link quality.
Flexible topology: Works with conditioned trunks and spurs; segment power conditioners and terminators fit standard FF H1 practice.
Seamless DCS integration: Designed for ABB process automation environments, easing commissioning and lifecycle service.
| Brand / Model | ABB CI570 (3BSE001440R1) |
| Product Type | Main Fieldbus Controller (FOUNDATION Fieldbus H1 LAS) |
| HS Code | 8537.10 (Boards/panels for electric control, ≤1000 V) |
| Communication Interfaces | FOUNDATION Fieldbus H1 segment (31.25 kbit/s) |
| Signal I/O Types | Fieldbus process data (publisher/subscriber function blocks, alarms, diagnostics) |
| Power Requirements | 24 V DC nominal (typical for this series; use a clean, regulated supply) |
| Operating Temperature | Typically 0…55 °C in a ventilated control cabinet |
| Installation Method | DIN-rail / cabinet mounting; follow ABB grounding and FF H1 termination rules |
| Dimensions & Weight | Compact module form factor; suitable for standard industrial enclosures |
Plants that already rely on FOUNDATION Fieldbus devices tend to get the most value. Typical cases include:
Oil & Gas / Petrochemical: Coordinated control of pressure/temperature transmitters and valve positioners on long H1 trunks.
Chemicals & Specialty: Deterministic execution of function blocks for sequence and batch skids.
Pharma & Biotech: Stable timing for regulated loops where documentation and diagnostics matter.
Power & Utilities: Robust segment control in balance-of-plant systems with mixed device vendors.
Water & Wastewater: Distributed field networks with large distances and many instruments.
One thing I appreciate is how it handles bus timing under load. A maintenance lead recently told me their CI570 kept the H1 loop steady during a device replacement, with the backup controller ready but never needed.
Reliability: Primary LAS control with proven stability and clean switchover when paired with CI571.
Compatibility: Works with multi-vendor FF H1 devices and standard segment components (conditioners, terminators, barriers).
Cost Savings: Reduces nuisance trips by stabilizing bus scheduling; simplifies commissioning and device replacement.
Lifecycle Support: ABB ecosystem, documentation, and tooling typically streamline upgrades and maintenance.
Cabinet & Environment: Install in a clean, ventilated cabinet. Keep ambient within the typical 0…55 °C range and avoid vibration.
Power & Grounding: Use a clean 24 V DC supply. Implement single-point grounding and maintain shield continuity as per FF guidelines.
Fieldbus Wiring: Use FF-compliant cable. Ensure exactly two terminators per segment (one at each end), and apply a suitable H1 power conditioner.
Topology & Loading: Keep device count within your power budget; in many cases 16–24 devices per segment is a practical ceiling depending on power and spur lengths.
Redundancy: For high availability, pair with CI571 3BSE001442R1 as the backup fieldbus controller.
Routine Checks: Review segment diagnostics, verify LAS/backup status, keep firmware aligned with your DCS version, and inspect terminations and shields annually.
CE compliant for EMC and safety (typical for ABB industrial modules)
RoHS compliant in most regions
UL/cUL recognition may apply depending on market version
Manufacturing quality: ABB facilities operate under ISO 9001 systems
Warranty: 365 days (provided by us, covering repair/replace)
CI571 3BSE001442R1 – Backup Fieldbus Controller for redundancy with CI570.
FOUNDATION Fieldbus H1 power conditioners – Segment power and short-circuit protection for spurs.
Terminators & barriers – Proper end-of-line termination and intrinsic safety where required.
Shielded FF cable & connectors – Maintain signal integrity and EMC performance.
If you’re consolidating spares or planning a segment expansion, the CI570 typically keeps your FF H1 loop disciplined and easy to troubleshoot—small detail, big difference during turnarounds.
