Most PLCs in FNQ have never been backed up. The program inside is the only copy — and when that hardware fails, you're looking at a full reverse engineering job or a rebuild from scratch. We extract and back up your PLC programs while they're running, so a hardware failure becomes a straightforward swap instead of a crisis. When we're on site for a PLC backup, we'll typically pull your HMI project files at the same time — because they go hand in hand.
Beyond backup, FNQ Controls Tech handles the full range of PLC software tasks — programming, modification, recovery, and communication configuration. We work across major international brands and the lesser-known PLC platforms that are increasingly common on imported machinery in FNQ — brands that most local automation companies simply don't support.
