How do you get a variety of building systems and machinery to communicate with a central system controller, when they use different protocols? 

Swedish system integrator Processcomponent AB had to solve this problem when they installed an energy monitoring system in a large apartment building in Gothenburg. 

The system gathers data from 72 individual apartments and a grocery store, and also from the central HVAC system for the entire building. 

The building owner wanted to present the data to authorized users in the building, so they could view their energy usage online and receive alarms in case of overuse. The data would also be used to invoice tenants and for other business reasons. 

The difficulty was that several water, power, and temperature sensors and meters communicated using M-Bus, but the controller used the Modbus/TCP standard.
