Absolute Magnetic Length Measurement System
7.3.5 Layer Setting Services (LSS services)
Exactly two conditions must be met for devices to be connected to a CANopen network - all
devices must have the same baud rate and every device must have a unique node address
within the network. The condition for a use under LSS is that there is a 1:1 CAN connection
with the device. A special dialogue mode then allows modifying the baud rate and the node
address.
COB-ID 0x7E5
is sent from the master to the slave, the slave answers with
COB-ID
0x7E4.
LSS messages are always 8-byte long. Unused bytes are reserved and should be filled
with 0.
A
„Switch Mode Global“
command is sent to switch a device in LSS configuration mode:
0x04
0x01
reserved
Unfortunately, this command is not confirmed.
The following command calls for the „Inquire Node-ID“ service.
0x5E
reserved
If the command was carried out successfully, the slave answers with:
0x5E
Node ID
reserved
If no feedback answer is received from the device, the LSS service may not be supported, or
the baud rate may be incorrect.
The „Configure Node-ID“ command is used to re-configure the node address:
0x11
Node ID
reserved
The error code is included in the answer of the slave device:
0x11
Error code
Error extension
reserved
Error code 0 means that the command has been accepted - Error code 1 indicates an invalid
Node ID.
The remaining error codes are reserved. The error extension includes manufacturer-specific
information can only be used in case of error code 0xFF.
The baud rate is activated with the command „Configure Bit Timing Parameters“.
0x13
