Combined Watchdog state of the QUAD M0/R0 stage has been made.
EPICS version of this signal is named like "H2:SUS-ITMY_M0R0_WDMON_STATE"
The simlulink model has the tap for the faster trigger, but not used for anyting right now.
The state signals are produced from the watchdog "blocking" signal of M0 adn R0 by taking "OR" logic of them.
This channel is designated to provide the state of the Quad suspension to ISI.
From the point of view of the suspension safety, ISI should be notified if the suspension top levels are not quiet and thus the active damping is not effective. The suspensions are enough quiet as long as the M0/R0 damping are functioningd. In that case, the L1/L2 watchdogs may trip with different reasons than the disturbance of the entire suspension, and therefore should not be included in the state notification for ISI.

Bandlimit filters for AC Watchdogs (ZERO[0], POLE[0.1, 10, 10]) and the ones for DC Watchdogs (POLE[10]) have now been
armed in the ITMX/Y FMX/Y suspensions by using AWESOME preparation script / easyquack combo!!!
