PLC Technician
Maintain and troubleshoot Programmable Logic Controllers to keep industrial systems running.
What is a PLC Technician?
PLC Technicians are responsible for the programming, maintenance, and troubleshooting of Programmable Logic Controllers (PLCs) used in industrial automation systems. They work with electrical schematics, instrumentation, and control systems to ensure optimal performance and minimize downtime. The role involves hands-on work, diagnostics, and collaboration with engineers.
A PLC technician spends the day reading schematics, installing and programming microprocessor-based instrumentation, and testing electromechanical assemblies with oscilloscopes and voltmeters. You calibrate hydraulic and pneumatic subsystems, verify part dimensions with precision instruments, and prepare written test documentation. Work is team-centered and indoors, with commissioning and troubleshooting under time pressure alternating with routine maintenance and assembly checks.
The hats you wear
