CAN Collect Functionality
For applications involving multiple PLM units, a single PLM can be configured to
collect calibrated lambda readings from up to 15 other PLMs on the CAN bus,
and to retransmit the 16 readings on a single CAN address. This functionality is
available in PLM firmware V1.1 and later.
Note that only the calibrated lambda reading is collected and re-transmitted. If
the CAN collect feature is used, PLM Diagnostic CAN messages may still be
turned on, but care must be taken in assigning addresses not to interfere with
messages from the other PLMs.
Configuring the CAN collect master unit (PLM 1)
Only one PLM on the CAN bus should be configured as a Collect Master.
To enable the CAN collect functionality, a base address and a message rate
must be specified in the Collect Master tab of the CAN Message Setup dialog.
