PXI/ PCI 61xx – User Manual
The
PXI/ PCI 61xx
controller board has up to four communication
interfaces onboard, designed as CAN, LIN or KLine interface (also
mixed up possible as multibus version). Two of the communication
interfaces have a preferred basic assignment, see
. The two
others may remain empty, but can optionally designed as further CAN,
LIN or KLine interfaces.
If required, the assignment can be changed by changing the
belonging transceiver (even the preferred assignment!).
Please proceed extremely carefully when changing transceivers,
and pay attention to their position and orientation.
The position of the transceivers and their assignment to the interface
number is shown in the following figure:
Each Transceiver type is coded and can be identified clearly.
For the available types of transceivers see
All four interfaces are supplied by an internal voltage of 12V
(UBAT
intern
). In case of using other voltages, this internal voltage can
be switched off individually by software.
G-API commands
G_Can_Node_InternalVBat_Disable
G_Lin_Node_InternalVBat_Disable
or
G_KLine_Node_InternalVBat_Disable
Then, an external voltage (UBAT
extern
) must be supplied via the
predefined pins of the frontal connector.
In case the internal power supply should be later used again, proceed
the
G_Can_Node_InternalVBat_Enable
G_Lin_Node_InternalVBat_Enable
or
G_Kline_Node_InternalVBat_Enable
G-API commands.
When using CAN-FD, the options LIN/ KLine are currently not
possible.
The CAN-FD Onboard Interfaces are based upon the “M_CAN”
IP-Module (Revision 3.2.0) of Bosch company, featuring the following
characteristics:
♦
CAN 2.0 Specification compliant (Parts A and B)
as well as ISO 11898-1:2015 Standard compliant
♦
Transfer of up to 64 Data bytes in one CAN-FD frame
♦
Support of the CRC Algorithmus in the CAN-FD frame
according to ISO 11898-1:2015
as well as Bosch CAN-FD Spezifikation V1.0 (Non_ISO)
