3.4 Function Detail
3.4.1 Device Management
Device Management function is supported by EJX910 HART/F OUNDATION fieldbus and
DYF(SoftDL) F
OUNDATION
fieldbus DTM.
F OUNDATION fieldbus Device DTM supports following blocks.
EJX910 F OUNDATION fieldbus DTM:
Resource block, Sensor Transducer block, Flow Transducer block, LCD Transducer block,
and AI function blocks
DYF(SoftDL) F OUNDATION fieldbus DTM:
Resource block, Transducer block, AI function blocks and AR function block
Parameters of other function blocks should be set and changed by other Fieldbus configurators.
IMPORTANT
Use function block scheduling and connection tool for DYFMVTool. After using these setting tool,
finish the program before starting FlowNavigator.
(1) Online Parameter
The Device General Parameters of the device can be edited directly in online status.
(Tag, Range, Unit, Damping, Lowcut, Indicator display)
(2) Offline Parameter
The Device General Parameters of the device can be edited and stored in offline database.
(Process value monitoring, Tag, Range, Unit, Damping, Lowcut, Indicator display)
(3) Downloads to or uploads from the device
The Device Flow Parameters and Device General Parameters stored in offline database are
downloaded to the device.
The parameters of the device is uploaded from the device and stored in offline database.
Device General Parameters:
HART or F
OUNDATION fieldbus parameters of the device, which can be modified with using
Device DTM. e.g. range, damping, etc.
User Flow Parameters:
The parameters which users input on EJXMVTool and DYFMVTool for flow configuration.
These parameters are used to only generate Device Flow Parameters and not downloaded to
the device.
Device Flow Parameters:
The parameters which EJXMVTool and DYFMVTool calculate and generate with using the User
Flow Parameters and are downloaded to the device.
