4.3: Application Specific Objects
4.3.1: Position Object (Class ID = 100)
There is a single instance of the position object for the DeviceNet Resolver. No class attributes are
supported. All the instances are gettable and settable. The table below shows the values:
Attribute ID Access Rule Name Data Type Value
1 Get/Set Magnet Position UINT Current Position
2 Get/Set Scale Factor UINT Current Scale Factor
3 Get/Set Direction USING Current Direction
Valid position values range from 0 to the current scale factor. Valid scale factor values range from 2 to
4096. Direction value 0 indicates that the counts will increase clockwise. Direction value 1 indicates that the
counts will increase counter-clockwise.
4.3.2: Setpoint Object (Class ID = 101)
There are eight instances of the setpoint object in the DeviceNet Resolver. No class attributes are
supported. All setpoint position data is gettable and settable. The setpoint status is gettable.
Attribute ID Access Rule Name Data Type Value
1 Get Setpoint Status BOOL 0x00
2 Get/Set Setpoint On Position UINT 0x0000
3 Get/Set Setpoint Off Position UINT 0x0000
Valid setpoint values range between, and include, zero and the scale factor.
(i.e. < setpoint < scale factor)
4.3.3: RPM Object (Class ID = 102)
There is a single instance of the RPM object for the DeviceNet Resolver. No class attributes are supported.
All the instances are gettable but not settable. The table below shows the values:
Attribute ID Access Rule Name Data Type Value
1 Get RPM UINT Current RPM Value
