Work related to K-Log#31618
[K1OMC0]
Model: k1omc
Add two 32KHz data to daq
K1:OMC-OMMT2_TRANS_QPDA1_DC_SUM_OUT
K1:OMC-AS_PDA1_DC_OUT
Changes other than the above
adc_0_28:as_pda1_dc
adc_2_{16,17,18,19}:OMMT2_TRANS_QPDA1_DC_SEG added.
K1:OMC-TRIG_SW to select and each filter bank.
K1:OMC-LSC_TRIG's AS_POW input added, compared to THRESOLD_HI and separated from existing parts.

[K1OMC0]
model: k1omc
Change of DAQ channel
Deletion: K1:OMC-OMMT2_TRANS_QPDA1_DC_SUM_OUT 32768
Change: K1:OMC-AS_PDA1_DC_OUT 32768 -> 16384
Added: K1:OMC-OMMT2_TRANS_PDA1_DC_OUT 16384
Added: K1:OMC-POS_{SPOL,PPOL}_DC_OUT 16384
Correction of OMC_TRIG_SIG
adc_3_18: add: OMMT2_TRANS_PDA1_DC input and FilterBank
Received K1:LSC2_OMC_POS_{SPOL1,PPOL1} and added FilterBank
Added TRIG_MTRX
LSC_TRIG:.
K1:OMC-LSC_TRIG_THRESHOLD_HI changed to K1:OMC-LSC_TRIG_THRESHOLD_HI_{TRANS,AS}
Added OR decision between ASPOW and TRANS
[K1LSC0]
model: k1lsc2
Added transmission to OMC model
adc_0_{22,23}: K1:LSC2_OMC_POS_{SPOL1,PPOL1}
I tested new OMC TRIG functions for DC PD protection.
Figure 1 shows the OMC signals when I intentionally turned on AS power trigger by changing the trigger threshold.
OMC lock was automatically turned off just after trigger signal was changed, so it seems to work well.
Figure 2 shows the OMC signals when OMC transmission reaches the threshold of the transmission trigger.
OMC transmission was reduced just after OMC transmission reaches the threshold, os it also seems to work well.
For the next step, we need to consider how to implement the protection function in the guardian.

Continued work on updating k1omc from the other day.
#1 Changed AS_POW to separate the input and output a triangle wave with offset.
#2 Changed from K1:OMC-PZT-HV1_OFFSET to K1:OMC-PZT_HV1_OUT16.
#3 The value in #2 above may cross 0 when the triangular wave is added.
Then, the positive and negative offsets are repeatedly reversed.
To prevent this, the offset and amplitude of the triangle wave was changed to take into account.
#4 Same reason as #3 above. The offset addition position was moved to after K1:OMC-PZT_HV1.
#5 The same thing as #3 occurs when overshoot occurs. Therefore, the threshold was changed to have an upper and lower limit.

=> #3 and #4 above are the same process, so I modified them for next time. No updates have been made to this model.
