3.9 Layer setting services (LSS) and protocols
The LSS-services and protocols, documented in CiA DS-305 V2.2, are used to inquire
or to change the settings of several parameters of the data link layer and application
layer of a LSS slave by a LSS master via the CAN network.
Following parameters are supported:
-
Node-ID
-
Baud rate
-
LSS address compliant to the identity object (1018h)
Thus it isn’t necessary to adjust the Node-ID or Baud rate by means of switches.
Access to the LSS slave is made thereby by its LSS address, consisting of:
–
Vendor-ID
–
Product-Code
–
Revision-No. and
–
Serial-No.
The measuring system supports the following services:
Switch state services
●
Switch state selective
●
Switch state global
Configuration services
●
Configure Node-ID
●
Configure bit timing parameters
●
Activate bit timing parameters
●
Store configured parameters
Inquiry services
●

Identification services
●
LSS identify remote slave
●
