Module IC200ALG266 reports an Internal Hardware fault upon detection of an A/D
conversion malfunction. The module detects this malfunction by applying a known
stimulus to the A/D conversion path and verifying the expected result. If an
unexpected result occurs three times consecutively, the module stops scanning,
turns off the OK LED, and reports an Internal Hardware fault. The module must
be power cycled or replaced to clear this fault.
