I though that the "C1LSC_TRIG_MTRX" MEDM screen completely controls the triggring of LSC signals. But today while trying to trigger the X-arm locking servo on AS110 instead of TRX, I found some strange behaviour. Summary of important points:
All very strange, not sure what's going on here. The simulink model diagram also didn't give me any clues. Need's further investigation.
