Configuration
Before you transmit a CAN object, you must configure
the CAN controller by selecting the <Config> menu
with the cursor keys and pressing <Enter>. The Config-
uration function determines the ports to be used and
their communication parameters.
The port configuration window is shown below.
The parameters below need to be configured for each
CAN controller:
Address segment:
The base address (address segment)
is normally adjusted during the installation process. The
selection of the address segment needs to be the same as
that of the hardware configuration.
Port:
Select the port you want to configure.
Baud rate:
The baud rate must be coordinated with the
CAN network. Choose the appropriate one from the list
of baud rates.
Acceptance code:
Specifies the value of the 8 most sig-
nificant bits of the identifier (ID10 ... ID 3)
Acceptance mask:
Specifies the bit positions which are
"relevant" for acceptance filtering.
Note: The acceptance code and acceptance mask are
configured through eight digits (1 digit per bit) using 0
or 1.
Example:
Acc Code = 11111111
Acc Mask =11111111
The shown acceptance filter will accept every received
message.
Interrupt:
Sets the interrupt for each port. Be sure that
this setting matches the IRQ already selected for the
PCM-3860, which accepts values between IRQ3 to
IRQ15, except 8 and 13.
Running mode:
During the normal configuration and
communication process, select Normal Mode. When
the system fails, you can hit <Enter> to reset the CAN
controller. Hit <Enter> again to further execute your
configuration.
Monitor:
Select the port to be monitored from the
<Monitor> pull- down menu. Press F3 to start and stop
the monitoring process.
