Configuring the Encoder Using RSNetWorx for DeviceNet
4-7
Enhanced Device Configuration in Online Mode
The Enhanced Device Configuration is selected by double-clicking
on the encoder symbol. In on-line mode the parameter values
currently stored in the encoder are accessed.
By clicking on the Apply or Download to Device buttons, the
parameters can be saved to the encoder. The updated encoder values
are stored in the encoder RAM and are valid immediately. Saving the
new values to the EEPROM is done with a separate command.
Saving Parameter Values to
EEPROM
Saving the parameter values to the EEPROM is performed in the
Class Instance Editor.
To access the Class Instance Editor, select the device in the graph
window and click on Class Instance Editor in the Device menu. Select
the service Save (16
hex
) of Class 2F
hex
(encoder object), Instance 1,
with the ‘Send the attribute ID’ box unchecked.
Finish by clicking on the Execute button.

Restoring Parameters to
EEPROM Values
In order to set the parameters to the EEPROM values, the service
Restore (15
hex
) of the encoder object is used.
This is done in the Class Instance Editor . Select the service Restore
(15
hex
) of the object 2F
hex
(encoder object), Instance 1, with the
‘Send the attribute ID’ box unchecked. Finish by clicking on the
Execute button..
!
ATTENTION:
The Restore function results in a
change of position reading. This can cause unexpected
motion which could result in personal injury and damage
to the product or equipment. During Resore, steps should
be taken to ensure the shaft is stationary and will remain
so.
