4.3.1 Storing Procedure
The parameter settings can be stored in a non-
volatile E
2
PROM. The parameter settings are
stored in RAM when being programmed. When
all the parameters are set and proved, they can
be transferred in one burn cycle to the E
2
PROM
by the parameter memory transfer.
The stored parameters are copied
after a RESET (Power on, NMT-
Reset) from the E
2
PROM to the RAM (volatile
memory).
Storing without Reset
By using the object 1010h from the
communication profile related object dictionary
you can store the parameters into the non-
volatile memory without a reset.
Storing with Reset
By using the object 2300h from the manufacturer
specific object dictionary you can store the
parameters into the non-volatile memory. After
storing the parameters a reset of the device is
performed.
4.4 Restoring Parameters
The default parameters can be restored by using
the object 1011h from communication profile
related object dictionary. The already in the non-
volatile memory programmed parameters are
not overwritten. Only after a new store command
the default parameters are stored in the non-
volatile memory. To restore the default
parameter the following telegram is used. The
restored parameters are equal for every type of
CANopen encoder and might not fit with the
status after delivery. Please check the restored
parameters before you store them to the non-
volatile memory.
4.5 Usage of Layer Setting Services (LSS)
The integrated Layer Setting Service
functionality is designed according to the CiA
normative DS305V200 CANopen Layer Setting
Service: General Description:
These services and protocols can be used to
inquire or to change settings of several
parameters of the physical, data link layer, and
application layer on a CANopen device with LSS
slave capability by a CANopen device with LSS
master capability via the CAN network. In case
of the new series, the encoder will be the LSS
slave device and the PLC (control) has to
support LSS master device functionality. The
LSS-functionality of the new series is limited to
the following parameters of the application layer,
namely node number and baud rate.
