Command Line of the Resource Manager for PCI Boards
The resource manager can be configured by means of the parameters described below.
Parameter Function
-h Showing a help text.
-n net
Assigning the logical network number.
net = 0...255
default: net = 0
-p index
Selecting the esd-CAN-PCI boards in the system.
The boards are numbered starting with ‘0’. The assignment of numbers and boards
is determined by the plug-and-play controller. In case of doubt, the assignment
should be checked by means of a test.
Table 37: Parameters of the resource manager on PCI boards
Example for the installation of two CAN-PCI/331 boards in one system:
Call Function
c331 -p0 -n0 &
The CAN network numbers 0 and 1 are assigned to the CAN-
PCI/331 module with the PCI number 0.
c331 -p1 -n2 &
The CAN network numbers 2 and 3 are assigned to the CAN-
PCI/331 module with the PCI number 1.
Table 38: Example for the installation of two CAN-PCI/331 boards
Now you can test the communication on the CAN bus by means of the example program cantest.
Attention! Make sure that your module is correctly wired! A second CAN participant is required
to make the module work correctly, because otherwise the CAN controller creates error
messages. Make also sure that the bus is correctly terminated.
