ABB CI626V1 is an Advant Fieldbus 100 communication interface for Advant Controller 110 and Advant Controller 160. The selected product identity is CI626V1 / 3BSE012868R1. ABB describes the V1 interface as using coaxial connectors and an integrated modem with full redundant-media support.
The AF100 manual distinguishes CI626V1 from the earlier CI626 and from the twisted-pair CI627. The CI626-family diagrams show two BNC bus connectors and drop-cable arrangements for single or redundant coaxial media. Redundant cables improve communication availability; they do not double bandwidth.
Before exchange, record the station address, bus configuration, controller position and cable routing. Keep bus continuity and termination consistent with the approved network arrangement and check traffic on both lines after commissioning. Use the exact V1 identity when quoting a spare because the predecessor has different redundancy limitations.

Preserve station addressing, bus configuration and both media routes. Verify communication on each coaxial line after replacement.
ABB lists full redundant-media support for CI626V1. The predecessor CI626 has reduced support, including a maximum 4 m cable-length difference between any two stations on coaxial media. Preserve the V1 designation in the order.
ABB identifies CI626V1 as a coaxial interface with an integrated modem. CI627 is the separately listed twisted-pair interface. Review the network media and approved conversion arrangement rather than treating the connectors as interchangeable.
No. ABB states that redundant cables increase availability, not communication bandwidth. Plan redundancy for continuity of service and validate the two routes separately.
The ABB diagrams place drop cables and BNC T-adapters between the bus and the interface. This arrangement preserves network continuity during an approved interface exchange; keep the installed topology and termination intact.
The manual specifies an address from 1 to 79 on the controller backplane thumb-wheel switch. For the CI626 family to read this setting, the interface is installed in the second AC110 backplane slot. Follow the controller procedure when changing it.
No. ABB gives 300 m for RG59 and 700 m for RG11. These are segment limits within the complete AF100 network rules, so repeaters, media conversion and total network design still require review.
For the CI626 family, traffic indication means that the modem detects receiving or transmitting activity on a line. Confirm application data and station supervision as well; traffic alone does not prove correct process values.
Preserve the installed configuration and station identity. ABB explains that valid nonvolatile configuration is reused on restart; compare the resulting operation with the approved project and investigate missing or inconsistent configuration before returning control to service.
Send the model, complete part number, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
