8.9 Preparing the restart
In the control technology system you can use the control to transmit the entire parameter
setting via SDO initialisation to the field devices when the machine is switched on.
According to DS301, the control always initialises the CAN parameters of the field devices.
Moreover, it can initialise further parameters. The values for this must be stored in the
control configuration under the Service Data Objects tab.
Usually, the control only transmits those SDO projects for which you have stored another
value than the standard value. The control does not compare these values with the existing
values in the field device. Thus, not all parameters changed there may be set correctly.
If you want that a factory adjustment is carried out in the field device before SDO
initialisation, go to the Parameter tab and set a checkmark at "Reset Node".
The Service Data Objects tab contains the codes which are written in the EDS file. The EDS
file contains all write codes.

Note!
When a node is reset, the parameter setting in the field device which you have
made with the »Engineer« or the »Global Drive Control« gets lost. For this reason
you have to transmit all parameter values manually to the Service Data Objects
tab. This only makes sense when commissioning is completed and all
parameters are optimised. If you change something afterwards via the
»Engineer« or the »Global Drive Control«, you have to maintain it in the PLC
program.
