The Repair Process
When an Allen-Bradley PLC or I/O system develops a problem, Control Concepts Dallas evaluates the affected equipment and surrounding operating conditions to determine whether the issue originates within the Allen-Bradley equipment or elsewhere in the automation system.
Our technicians review incoming power, controller status, communication networks, electrical connections, I/O modules, connected field devices, and overall system performance. When appropriate, PLCs and modules are powered and tested to verify communication and input/output operation, including analog, digital, communication, ASCII, and special-function modules.
Once the cause is identified, we recommend the most practical solution, whether that involves component-level repair, module replacement, retrofit, or modernization. Routine inspection, clean operating conditions, secure electrical connections, and dependable communication networks can also help reduce unexpected problems.
Many PLC failures can be avoided through preventative maintenance.
