Cognex Vision Systems Troubleshooting & Procedures

Step-by-step procedures

• Cognex In-Sight Not Acquiring — Online/Offline & Trigger Checks — When a Cognex In-Sight camera stops grabbing images, the cause is usually the Online/Offline state, a missed trigger, or an editing lock — not a broken camera. Work these checks before swapping hardware.
• Cognex In-Sight to PLC Communication — Profinet & Modbus TCP Setup — Wire a Cognex In-Sight vision system to a Siemens or Allen-Bradley PLC over Profinet and Modbus TCP. Covers In-Sight Explorer network config, GSDML import, Native Mode vs industrial protocol tags, and the common pass/fail data map.
