ABB CI570, article number 3BSE001440R1, is a MasterFieldbus communication interface documented for Advant Controller 450 systems. It installs as a controller hardware option to connect the engineered MasterFieldbus arrangement and exchange controller data across the configured bus.
CI570, article number 3BSE001440R1, restores the documented MasterFieldbus interface role in a compatible Advant Controller 450. Confirm the carrier, controller execution, fieldbus wiring and redundancy design before replacement.
Important Notice: Confirm the complete model, revision and installed system before replacement.
Interface purpose: ABB identifies CI570 as the MasterFieldbus interface for Advant Controller 450. It must remain matched to the original MasterFieldbus project rather than being treated as an interchangeable CI-series communication module.
Controller relationship: The interface operates as an AC450 hardware option within the documented controller and carrier arrangement. The complete 3BSE001440R1 marking and installed system design determine the correct replacement.
ABB states that the CI570 MasterFieldbus option may be combined for dual redundancy. A replacement therefore requires confirmation of whether the installed interface is single or paired, together with the controller execution, carrier position and project configuration.
Do not assume that inserting a second module creates redundancy. The complete Advant Controller 450 architecture, fieldbus wiring and configured operating role must already support the documented redundant arrangement.
Install CI570 only in the carrier and slot defined by the Advant Controller 450 project. Verify the backplane connection, fieldbus cable and termination, controller hardware execution and any paired interface before applying power.
After installation, restore the approved controller database and confirm communication status under site procedures. Retain the original article-number record so future maintenance can distinguish CI570 from other ABB communication submodules.
Engineering check: Allocate CI570 to the correct Advant Controller 450 slot and MasterFieldbus segment. Verify controller configuration, interface identity, bus address and termination, keeping the installation within the documented capacity of Up to 7 CI570 interfaces.
Acceptance test: Where dual redundancy is configured, match both interfaces by revision and network parameters, establish synchronization, and perform an authorized link-path interruption while checking telegram continuity and diagnostic recovery.
CI570 belongs to the legacy Advant Controller 450 hardware platform. ABB documents System 800xA and AC 800M as the modernization path for legacy Advant control installations; there is no assumed drop-in replacement for CI570, so the fieldbus architecture and migration scope require ABB-qualified engineering review.
Moore Automated supplies inspected ABB CI570 replacement modules and legacy spare parts matched to article number 3BSE001440R1. Exact nameplate and project checks provide a practical service solution that helps reduce downtime while a longer-term modernization plan is evaluated.
