Missing DAC not showing up in IOP status word
An 18-bit DAC has failed (fallen off the PCIe bus) on l1sush34. However, the IOP status word is still all green. (GDS_TP screen attached). It is also shown in the FE_STATS screen (also attached).
Such an error should percolate up to the overall word (at least in the case where the DAC existed when the IOP was started, but now does not)
