Most contractors stop at the wiring. Most IT shops won't touch a control panel. We sit in the middle.
Industrial IT means we plug a laptop into the machine, read what the touchscreen and the PLC are saying to each other, and fix what's broken in the comms.
Sometimes that's a wiring fault. More often it's a settings mismatch, a missing backup, or a network the original installer never documented. The work sits between two trades that don't normally cross over: the sparkie who wires the panel, and the office IT shop who runs the network upstairs.
If you've ever had two electricians look at a screen that won't talk to the PLC and walk away, that's the job we get called for.
Real callouts from across Far North Queensland. The shape repeats: a panel that's been there 15 years, no source files, no drawings, an OEM gone or unreachable, and a line that needs to keep running.
Roll forming line. Touchwin HMI nobody had source files for. We plugged a laptop into the running panel, sniffed the live Modbus traffic, decoded the stream, and rebuilt the project clean on a new Touchwin. Like for like, no operator retraining. Two contractors had already passed.

Most of our jobs. Old PLC, old industrial touchscreen (HMI), no spares. We work with what's there, document what's actually running, and hand you a backup before we leave.

Managed switches. Modbus / Ethernet/IP / RS485. IT/OT segregation. The plant-floor side of the network nobody else in Cairns is set up to handle. We design it small, document it, hand it over.
Network & comms recoverySoftware background. Spent over a decade building systems for high-reliability environments before relocating to Far North Queensland and seeing the gap firsthand: nobody local who could plug a laptop into an industrial touchscreen, read the comms, and get the line running again.
FNQ Controls Tech brings that background to plant-floor work. Structured problem-solving, proper documentation, clean handovers. The same approach that keeps high-reliability systems running, applied to the equipment your business depends on.
Good. We collaborate. Your electrician handles the wiring, the licensed work and the panel hardware. We handle the software, the comms, the program inside the touchscreen.
Even better. They keep the office network running. We handle the OT side: the industrial network behind the SCADA, the panel PCs, the protocols their tools don't speak.
That's what matters. We work around it. Most jobs we can clip onto the running PLC and read the comms without dropping the line. We confirm before we touch anything.
No drawings, no backup, no source files, no one left who knows the system. That's most of our jobs. We work with what's there.
Same-day callouts in Cairns metro. Same week across FNQ. We'll tell you within an hour if it's solvable.
