The gateways come pre-configured from Honeywell with the full 244-byte memory map. The
data map contains four sections: alarms, faults, heartbeat, and concentrations. Some
automation strategies may wish to read a subset of the data to conserve network bandwidth or
scanner memory. For example, some may wish to read only bytes 0 to 82 and ignore the
concentration integers in higher memory.
