What Access Systems Can Do Elevator Control In A Completely Standalone Mode Comm Is Down?

Scenario:

Elevator control of multiple cabs in high rise building. Current access control system uses groups of IP-based relay boards to activate the various floor call buttons a resident can go to after they swipe their valid credential.

The card reader is connected to a controller that can operate in a standalone mode if network comm goes down, but it is merely a way for the system to know who swiped their credential. The heavy lifting is done by an elevator control application that resides in the server hosting the access software (Windows based PC). This app communicates to the IP-based relay boards which relays to fire, which in turn tell the elevator controls which floor buttons are active for that person.

If this Windows PC is turned off, loses power, or re-starts for any reason such as a software update, the elevator controls stop working. There are Windows Services set up that automatically re-start when the PC starts up and alllow (should allow) the elevator controls to start working again, but the lack of a failsafe or standalone mode is not acceptable.

Elevator controls are always a lot more involved and prone to a learning curve since this is not as common a use case as controlling a door lock or gate with a 1:1 relationship between the reader and the door.

Whose elevator control modules within their card access system provide a reliable and easy to program set up and still work (at least to some degree) in a fail safe mode or don't rely on a Windows PC to work?

Thanks in advance
