Electrical signal integrity is the bedrock upon which programmable automation controller functionality, reliability, and accuracy depends. The heat, dust, corrosive chemicals, moisture, and vibration common to many work environments can degrade wiring and connections, creating a harsh electrical environment and degrades signal quality.
Beyond the basic electrical measurements, this application note discusses:
- Digital troubleshooting on the physical layer
- Analog troubleshooting on the physical layer
- Troubleshooting 4-20 milliamp process control loops
- Loop malfunctions
- Checking PAC I/O cards
- Data analysis
