A homebrew BACnet/IP implementation. Does a discover, a read and a write of commonly used objects (AI, AO, MI, MO, DI, DO etc....). uses subs for each method so if you want a BACnet/iP instance discover tool just write a simple strategy, add the sub and run on PAC Sim.
i know its been on the forums for a while, its slightly more than a sub or some code and its originality isn't super, but the comments and portability make up for it!! (hopefully...)
