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.
Word 2 Discrete Input Register
This word contains a right justified binary 16 bit data field.
Bit(s) Description
15 ... 9 Not used
8 0 = bad module health (loss of communication to the base)
1 = healthy module)
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.
