CSA,very glad to receive your response.
Your explanation on L2FSTG is enlightening,and i think i should not read siganl names literally.
As for this thread is very long and disorganized, i open the part 3 thread.

L12HF_ALM = CONTROL SPEED SIGNAL LOSS - HP
L12HFD_C_ALM = CONTROL SPEED SIGNAL TROUBLE
L12HFD_P_ALM = PROTECTIVE SPEED SIGNAL TROUBLE
L12H_P = VPRO HP Overspeed Trip
L12H_ACC = VPRO - Loss Of Protective Speed Signal
<b>L12HF_ALM</b><pre>
L12HF L12HF_ALM
--------||------( )</pre>
L12HF = Loss of control speed signal
L12HF_ALM = Control speed signal loss
I think this signal is similar to L12H_FLT,and L12H_FLT is for protective HP speed signal.
<b>L12HFD_C_ALM</b><pre>
L12HFD_C L12HFD_C_ALM
--------||--------()</pre>
L12HFD_C = HP overspeed fault - control input trouble
L12HFD_C_ALM = Control speed signal trouble
<b>L12HFD_P_ALM</b><pre>
L12HFD_P L12HFD_P_ALM
--------||--------()</pre>
L12HFD_P = HP overspeed fault - Protective input trouble
L12HFD_P_ALM = Protective speed signal trouble
I think L12HFD_C_ALM and L12HFD_P_ALM are similar too, both of these two signals are indicating that TNH and TNH_OS are not matching.
<b>L12H_P</b>
L12H_P = VPRO overspeed signal
It is overspeed signal,and it comes from VPRO card. I was curious whether it should be lower case.
<b>L12H_ACC</b>
L12H_ACC = VPRO-Loss of Protective Speed Sigal
It is a signal that comes from VPRO card.
<b>In conclusion, siganls in L4PSTX3 rung are all related to speed siganls.</b>
