Part Repair & Sourcing
AS-i Gateway Repair
AS-Interface gateways and decentralised network hardware.
- 7-day standard turnaround
- 12-month warranty
- Free UK-wide collection
Faults we see most
- Network dropping out, or slaves intermittently disappearing
- Gateway not enumerating on the higher-level bus
- Configuration not holding through a power cycle
- Dead or erratic I/O
- Display or diagnostic LEDs indicating a persistent fault
- Unit dead after a supply event
How a repair is proven before it comes back
Nothing is signed off on a power-up. Every unit in this category goes through:
- Communications verified on both the AS-i side and the upstream bus
- I/O exercised channel by channel
- Configuration retention confirmed across power cycles
- Soak testing before release
- Full fault and repair documentation returned
Board-level rework is carried out by IPC7711 and IPC7721 certified technicians working to ISO 9001:2015, and the test evidence comes back with the unit.

How a repair actually runs
Four stages, one point of contact throughout. You deal with us; we deal with the workshop.
-
We collect
Tell us what has failed and where it is. Collection is arranged across the UK at no charge, and the unit is booked in against your account with its serial, its symptoms and who reported them.
-
We diagnose and quote
The unit is bench-tested to confirm the reported fault before anyone opens it, then stripped to component level. You get a fixed quote and an honest verdict — including when replacement is the better buy.
-
We repair
Board-level rework is carried out by IPC-7711/7721 certified technicians working to ISO 9001. Failed components are replaced with tested equivalents, not bodged around.
-
We prove it, then return it
Nothing ships on a continuity check. Units are soak tested, load tested and exercised against manufacturer software, and come back with the test evidence and a 12-month warranty.
Common questions
Why does an AS-i gateway failure cause so much disruption?
Because the gateway is the bridge between field-level sensors and actuators and the higher-level control system. When it fails, the controller loses visibility of everything below it — so a single small component takes out a whole run of conveyor or a complete machine cell.
That makes gateways a strong candidate for holding a repaired spare rather than waiting on a replacement when one drops.
Can you repair the gateway without our network configuration?
Diagnosis and repair do not need it, but final verification is better with it. Where the configuration cannot be supplied, the unit is tested against a representative network instead.
Got a unit that needs looking at?
Send the make, model and what it is doing. You will get a straight answer on whether repair is the right call.
