I/O module AI overvoltage

What does 7086 mean?

An overvoltage condition has been detected on an Analog Input (AI) of an I/O module. The AI automatically switches to voltage mode from mA mode as a protective measure. If the high signal level persists, it could damage the input circuit or lead to inaccurate process feedback.
