Abstract
An arrangement includes a first computer having a first operating system, the first computer having a memory containing software derived from field controller software executed on physical field controllers of a building control system. The physical field controllers employ a second operating system. The software further contains an operating system abstraction layer operable to convert at least some operating system calls of the field controller software to corresponding calls in the first operating system.
