Proven Test Methods
• Custom-engineered test fixtures support multiple communication protocols, including PROFINET, PROFIBUS, ControlNet, DeviceNet, Modbus, RS485/RS232, and EtherNet/IP.
• Utilize dozens of PLC controllers, incorporating GX Works, STEP 7, and Studio 5000®, among other software packages, to monitor inputs and send outputs.
• Proficient in IEC 61131-3 and master graphical and textual languages, such as ladder logic, function block diagrams, sequential function charts, structured text, and instruction lists.
Restore to OEM Specifications
• Remove contaminants and perform Electrical Signature Analysis (ESA)
• Each PLC undergoes critical 48-hour burn-in testing to identify weakened, potential heat-related failures
• Repair or replace out-of-spec components, then retest PLC to verify performance
• Specialized test fixtures use OEM equipment and software to replicate a production environment, reducing failure rates
