OK
The module receives power from the backplane power supply. No external power source is
required for module operation. Power for the user’s transceivers must be supplied from an
external source.
Intelligent processing for this module is performed by the CPU or NIU. The module
provides 15 words of analog input data.
LED Indicators
The green OK LED is on when backplane power is present, internally generated field
power is functioning properly, the module has been configured, the module has been
recognized on the backplane, and all diagnostic tests are executing as expected.
Diagnostics
The module reports a Loss of Internal Power fault for field-side circuits.
The module 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.
Configuration Parameters
The analog inputs are software-configurable to either default or hold last state upon loss of
module.
