The Heat Value Data Manager (HDM) is a powerful HGC family component, which adds valuable data management function to the analyzer.
The HDM303 is a Fieldbus device and is completed by LAS (Link Active Scheduler) which acts as the "brain" when it comes to scheduling and controlling Fieldbus communication.
Model HDM303 also has a Data storage function which functions as a back up system. For the fiscal measurements system purpose, 20 PV's from the Heat Value Gas Chromatograph will be converted to the floats data type of Modbus, and transferred to the Modbus master device as request. The HDM303's multi serial port allows users to connect the other Modbus master devices in parallel.
