A municipal or utility depot runs two separate worlds side by side — the building systems that keep the depot itself running, and the vehicle and yard systems that keep the fleet moving. Both generate signals constantly: a generator panel alarm in the building, a fuel tank sensor at the yard, a gate access fault at the entrance. Most teams manage these through two unrelated systems, which means nobody sees the full picture of what is actually breaking down across the site. PLC optimization brings both signal streams into one place. OxMaint reads building PLC signals and depot or vehicle system signals side by side, converting both into one prioritized work order queue instead of two disconnected alert lists.

A fuel sensor fault and a generator fault should not live in two different systems with two different review habits. One queue means nothing depends on who happened to check which screen.
Integration Points Across a Typical Depot Site
| System | Signal Captured | Typical Action Created |
| Building generator panel |
Failed start or low fuel |
Urgent work order, escalates if unacknowledged |
| Yard fuel tank sensors |
Low level or dispensing fault |
Refuel or repair ticket before fleet impact |
| Gate access control |
Reader or barrier fault |
Routed to depot maintenance, priority by shift timing |
| Vehicle wash bay PLC |
Pump or sensor failure |
Logged against the bay asset, scheduled for repair |
Expert Review
"Depot sites are where I most often see two maintenance cultures running in parallel — a building team and a fleet or yard team — each with their own alert habits. Merging the signal streams doesn't just save time, it surfaces problems that sit exactly at the boundary, like a generator fault that's actually about to affect vehicle charging."

Frequently Asked Questions
Can OxMaint combine building PLC signals with vehicle telematics or yard system signals?
Yes. OxMaint is built to ingest signals from multiple source types — building PLC and BMS systems alongside depot and vehicle system integrations — and route them into one shared work order queue.

Do building maintenance staff and fleet or yard staff need separate logins?
Each technician sees the work orders relevant to their role, while supervisors can view the combined queue across both building and depot systems from one account.
How are priorities decided when both a building fault and a yard fault occur at the same time?
Each signal type is mapped to a priority level during setup, so a generator failure and a routine gate sensor fault are queued by actual urgency, not by which system happened to report first.
Book a demo to review priority configuration.
Can a single depot site report on building and fleet maintenance separately if needed?
Yes. Even though signals flow into one queue, reporting can be filtered by system type, so building and depot maintenance performance can still be reviewed separately when required.
How long does it take to bring both signal tracks into OxMaint for one depot site?
Most single-site rollouts have the building PLC integration live first, with depot and vehicle system signals added shortly after, typically within the same setup cycle.

Stop Running Two Maintenance Systems for One Site
Building signals and depot signals tell two halves of the same story. OxMaint puts them in one queue so nothing gets missed at the boundary.
