8.3.3 CAN Row Counts
PCM2 supports row counters on CAN input channels.
Row counters allows multiple channels being transmitted within the same identifier and the system
will look for rotating data channels. This feature will help reducing the CAN bus load.
In the example below, 3 data channels are imported within the same position, bytes 2 and 3 in
identifier 0x300.
PCM2 will read “Shift Pressure” from this location when the row count value is 0, it will read “Oil
Pressure” from this location when the row count value is 1 and it will read “Fuel Pressure” from this
location when the row count value is 2.
To use input row counters tick the box
