Restoring Parameters; Usage Of Layer Setting Services (Lss) - Pepperl+Fuchs Absolute Rotary Encoder Manual

Absolute Rotary Encoder
Configuration
Note!
The stored parameters are copied after a RESET (Power on, NMT-Reset) from the E
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.

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.

Usage of Layer Setting Services (LSS)

LSS with photoelectric rotary encoders
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 OCD-II-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 OCD-II-series is limited to the following
parameters of the application layer, namely node number and baud rate.

Table 8.6
The LSS master device requests services that are performed by the encoder (LSS slave
devices). The LSS master device requests the LSS address from the LSS slave device. The
LSS address is defined in object 1018h Identity Object - it consists of vendor-id, product-code,
revision-number and serial-number as shown in Table 10. After receiving this information the
control can unequivocally identify the encoder and the node number and baud rate can be set.
The exact procedure varies in detail, coursed by the different PLC tools.
