Net Update
Global data is sent every time it's state changes. If it has not been sent in the time defined by the network
update time-out, it is sent at that time. The network time-out is the maximum time that can elapse without
broadcasting network data. If the data changes every scan this is the minimum time that can elapse
before data is transmitted. If the time-out is set to zero, the data is sent only on change of state.
