IC693DSM302-AE GE — Consistent configuration

Just like local I/O modules, the individual S900 Process I/O sta

tions can be configured directly, using the engineering tool inte

grated in the Distributed Control System (DCS). A special Device

Type Manager (DTM) exactly “knows” the functionality and pa

rameters of the individual functional modules. Besides the module

configuration, the DTM also provides for forcing (simulation) of the

inputs and outputs and for display of the diagnosis messages.

Due to the standardized FDT/DTM interface the DTM can be

easily integrated in the configuration tool of the DCS. Since the

DTM belongs to the instrument and not to the DCS, the user has

to get familiar with the operating procedure only once. The com

plete configuration and all parameters are automatically loaded

into the S900 stations when the bus network is starting up or upon

replacement of a hardware component. So, this is a real “plug &

play” system.

In consequence, there is no local service interface for the commu

nication interface, since it is no longer needed. The configuration

and parameter data is exclusively visualized and updated by the

DTM. The data is stored in the central database of the engineering

tool. Thus, system-wide data consistency is ensured. The applica

tions needed for commissioning and trouble-shooting are reduced

to the minimum. A putting into operation is also possible via using

a GSD file.
