In my case, I had a pile of outputs used in between KAM's XOVR's and RB's triggering other items. The counters are easy enough to modify and tweak just the same as the output, I used them to create access windows to enable/disable users based on time and day. The part of the logic equation for greater than, etc. takes that issue and then you decrement it to disable access, depending on how you want the person to lose access (time window, arm/disarm cycle, day of week, etc.)
Depending on the equation(s) and variables involved, that determines whether or not they get locked out, just have to take into consideration how much to "throw on the counter" and increment so if the date/time is within spec, then, for example, with enough "on the clock" so to speak, they'd be able to arm/disarm within their window multiple times, however once the clock struck midnight on their access, the decrement is automatic to below the threshold that allowed access in the first place.
If the counter is set appropriately to automatically increment by day, IE:14 allows access, then you have that user's disarm add 10 to that #, which would allow them multiple arm/disarm cycles, then at the end of their access window or day, then you pull the access down to a threshold that doesn't allow access or enable that user until it auto increments to that point.
It's just another way to accomplish the same thing, and the boolean choices are slightly more robust than a toggle.
That said, I wouldn't want to have to do this with a lot of users to create access windows and limit the users further, but I had a cleaning crew scenario, just not bi-weekly, and I also had a keyed shunt switch that was only enabled via a schedule, which would allow them to come in, use a code (credential accually) to gain access and disarm, and the shunt switch was designed to shunt interior protection in areas they were working in, but leave the perimeter armed. The system would auto re-arm the interior unless the shunt key was installed.
There were REX motions installed with KAM's/readers at the doors used for access so they'd auto-relock after someone walked out, keeping the building secure per se, with reports sent on a forced door or prop using outputs to trigger zones (as non-burg) to the CS.
Granted, this isn't the same as a full blown access control system and panels, like C-Cure, AMAG, Linel, CardKey or others, but in a small access control setting with security, it is doable.
