Technical cases
Anonymized examples showing method, tools and verification.
CASE 01 · ABB ROBOT
Intermittent robot stop under load
Problem: The robot cell stopped irregularly during cycle. Analysis: I/O status, sequence conditions and RAPID logic were traced during operation. Result: The fault area was isolated and a controlled restart could be verified.
Discuss robot troubleshooting →CASE 02 · VISION
Image set timeout
Problem: The vision flow generated sporadic timeout alarms. Analysis: Camera trigger, cycle sequence and wait states were compared. Result: The risk area for false timeout events was identified and verification points were defined.
Discuss vision systems →CASE 03 · PLC / FIELDBUS
Intermittent communication fault
Problem: Temporary communication loss between PLC, drives and field devices. Analysis: Diagnostic buffer, network status and signal loss were reviewed. Result: The fault chain was narrowed for targeted action and follow-up.

Method
Clear process, fast isolation and verified restart.
01
Observe
Confirm symptoms, production mode, alarms, cycle status and operator notes.
02
Trace
Follow signals through sensor, PLC, robot, camera and communication layers.
03
Verify
Test the hypothesis, check repeatability and confirm a safe restart.
04
Stabilize
Monitor production and document the action, risk and next improvement step.
