5.8.12 LSS

The FX -CAN uses the layer setting services and protocols, to configure via the CAN network the Baud Rate
3U
and the Node Address of an LSS slave device that is sealed against harsh environments and that does not
have any hardware components like DIP-switches for setting the node-ID or bit timing parameters.
Within a CANopen
has to be the active NMT-Master.
To activate the LSS Master, configure in the Object dictionary:
• Index H1F89:
The Boot time out. The time shall be longer than the boot time of the NMT-Client, which needs the longest
time for boot-up (Power On until Boot-up message).
• Indexes H1F84 to H1F88, the Sub-index which corresponds to the Node-Id which shall be set at the LSS-
Client:
The Identification information which is available at the Object dictionary Indexes H1000 and H1018 at the
LSS-Client.
• Index H1F81, the Sub-index which corresponds to the Node-Id which shall be set at the LSS-Client:
Set bit 0 NMT Slave, bit 2 NMT boot slave and bit 3 Mandatory device.
If the LSS Slave is not found on the configured baud rate, the FX
to find the LSS Slave. Through communication with a different baud rate, it can come to a Bus off condition at
the other devices in the network. If the device does not support automatically recovering from Bus off or
needs too much time for recovering, it's not possible to configure the LSS-Client.
It is recommended to establish a Point to Point connection for the configuration and to delete the Serial
number entry (Index H1F88) after configuration to prevent an unwanted start of the LSS Master.
→ For NMT slave identification, refer to Object Dictionary Index H1F84 to H1F88 in Subsection 5.8.4
Note
Check if the LSS-Client has activated an internal Bus termination. If necessary, deactivate the Bus
termination first to prevent unwanted behaviour of the connected nodes on the bus.

5.8.13 Configuration manager

The Configuration manager provides mechanisms for configuration of CANopen
network. For saving and requesting the CANopen
The sub-indexes are according to node-ID. The Configuration manager can be only used on the active NMT
Master.
Note
If during the Configuration upload to the NMT slave a failure other than SDO access failure at read only
Indexes and Sub indexes occurs, the configuration will be stopped.

network, only one LSS-Master is allowed to exist. For the LSS-Master Mode the module
→ For Boot time, refer to Object Dictionary Index H1F89 in Section 5.6
→ For configuration, refer to Object Dictionary Index H1F81 in Subsection 5.8.7
