Activate Bit Timing Parameters Protocol; Store Configuration Protocol - TR-Electronic CANopen+Multi-Sensor LP-46-K Benutzerhandbuch

3.8.4.3 Activate bit timing parameters protocol

The given protocol has implemented the Activate bit timing parameters
service. The protocol activates the Baud rate which was configured about the
Configure bit timing parameters protocol and is performed with all LMT
slaves in the network which are in the Configuration Mode.

Switch Delay
The parameter Switch Delay defines the length of two delay periods (D1, D2)
with equal length. These are necessary to avoid operating the bus with differing
Baud rate parameters.
After the time D1 and an individual processing duration, the switching internally in
the LMT slave is performed. After the time D2 the LMT slave responses with CAN-
messages and the new configured Baud rate.
It is necessary:
Switch Delay > longest occurring processing duration of a LMT slave

3.8.4.4 Store configuration protocol

The given protocol has implemented the Store configuration service. By
means of the LMT master the configured parameters of a single LMT slave in the
network can be stored into the non-volatile memory. Only one device is to be switched
into Configuration Mode. When the protocol is executed the LMT slave will be
reset, an emergency with COB-ID 0x80 + Node-ID and error code 0x00FF 00FF is
transmitted. The LMT slave is switched into PRE-OPERATIONAL state.
