Word 1 | The status word (word 1) contains information about the health of the module and | |||
| the status of the discrete outputs, including over temperature or short circuit of the | |||
| discrete outputs. |

| 0 | = bad module health (loss of communication to the base) |

|
| 7 (Channel 8) |
| 0 | = fault |
|
|
| 1 | = no fault |
|
|
|
|
|
| 6 (Channel 7) |
| 0 | = fault |
|
|
| 1 | = no fault |
|
|
|
|
|
| 5 (Channel 6) |
| 0 | = fault |
|
|
| 1 | = no fault |
|
|
|
|
|
| 4 (Channel 5) |
| 0 | = fault |
|
|
| 1 | = no fault |
|
|
|
|
|
| 3 (Channel 4) |
| 0 | = fault |
|
|
| 1 | = no fault |
|
|
|
|
|
| 2 (Channel 3) |
| 0 | = fault |
|
|
| 1 | = no fault |
|
|
|
|
|
| 1 (Channel 2) |
| 0 | = fault |
|
|
| 1 | = no fault |
|
|
|
|
|
| 0 (Channel 1) |
| 0 | = fault |
|
|
| 1 | = no fault |
|
|

|
| |||
| Note: The output fault bits and the corresponding discrete output are latched OFF | |||
| when a short circuit or over temperature condition is detected. To reset the fault | |||
| condition and make the output operational, the output bit that faulted needs to be | |||
| set to an OFF state. | |||
