Saving / Restoring Parameters
Management of
Saved
Parameters
During initial power up, the Advantys splitter box is initialized with the default
parameters. During subsequent power ups, it is initialized with the saved
parameters.
Updating Default
Parameters
Saved parameters are only applied once the speed on the Advantys splitter box has
been detected.
Saving and
Resetting
Parameters
The back-up of parameters is performed by writing a signature to the object 1010H
(see Object 1010H: Store Parameters, p. 146) These parameters will be used during
the next start-ups.
Saved parameters are reset with the default values by writing a signature in the
object 1011H (see Object 1011H: Restore Default Parameters, p. 148).
Recommen-
dations to Avoid
Data Losses
While writing or deleting saved parameters, the slave no longer processes
communications received via the CANopen bus. During this operation, none of the
messages transmitted to the slave are taken into account (this includes SDO or
Node-Guarding messages).
In order to avoid equipment damage or injury to personnel as well as any losses of
data, it is not advisable to initiate parameter saves or restitution when the equipment
is in "Operational" mode.
Note: When the master detects the presence of the splitter box on the network, the
parameters of the splitter box that are re-defined in the master's configuration tool
are overwritten.
RISK OF UNINTENDED EQUIPMENT OPERATION
The splitter box must be switched to the "Pre-Operational" state to save its
configuration. The saving process takes 1 to 2 seconds. If the save takes place in
the "Operational" state, the outputs will not be updated during the saving process.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.
