Channel cross-talk error

What does 28 mean?

Cross-talk was detected on a safety I/O channel, indicating unwanted signal interference between channels. This can be caused by improper shielding, close proximity of signal wires, or a faulty I/O module. This is a severity 3 error.

• Electrical interference between adjacent analog input channels.
• Signal noise on one channel affecting another.
• Improper shielding of input wiring.
• Faulty sensor signal conditioning circuitry.

Click steps to track your progress.

1. 1

   Check the wiring of the I/O module, ensuring proper cable routing and shielding to prevent signal interference.

2. 2

   Restart the I/O module to clear any temporary communication or internal state issues.

3. 3

   If the error persists after verifying wiring and restart, replace the I/O module.
