Processor faults, I/O failures, and lost communications across the major PLC platforms, repaired off site where a board can be fixed and troubleshot on site when it cannot wait. We support Allen-Bradley, Siemens, Omron, and the legacy families most shops have given up on.
Tell us the processor family and what the machine stopped doing, and PLC troubleshooting can usually be narrowed to the processor, the program, or the field wiring before a tech is on site.
Every call begins with the basic PLC troubleshooting steps: power supply, I/O status, and comms, all checked in place before anything is pulled off the rack. What we find and what it will cost is confirmed with you before parts are ordered.
PLC repair services then cover board-level fault finding and repair on SLC 500, MicroLogix, CompactLogix, ControlLogix, and PLC-5 racks, along with Siemens S5 through S7-1500, Omron, Mitsubishi, GE Fanuc VersaMax, and Modicon. Where a program is corrupted or missing, we restore from your last known backup or rebuild the logic from the machine's sequence, and you keep a copy of the working program when we leave.
