2.5.2
CAN connection to CANSAS
The CANSAS-module possesses a full-grade CAN (Controller Area Network) connection for transmitting
measurement data, and can send messages at up to 1MBit/s. The CAN-connection is a node on the CANBus, to which any number of CAN-devices can be connected.
The CAN-Bus can be considered a sort of line. The beginning consists of a CAN-Bus-terminator, which is
connected to the first node either directly or via a serial cable. The second node is connected to the first via
another serial cable, etc. After the last node, there is another CAN-Bus-terminator.
The serial cables used are commercially available, plated-through cables for the PC's serial interface.
A special CAN-Bus terminator can be ordered which runs up the module in its original state, without any
configuration. This makes it easily possible to reconfigure the module if it ever becomes impossible
otherwise.
2.5.3
CANSAS analog connections
The CANSAS-module's measurement input connections consist of two sockets for two separate sets of
measurements. Depending on the module type, either four or six differential channels can be connected.
For ease of connecting, special imc plugs having screw terminals can be ordered. The pin configuration
and measurement process are described in the appendix.
2.5.4
Checking connections
A dialog called from the menu item in the CANSAS interface's ‘EXTRAS’ menu lets you make settings for
the CAN-Bus access and for interface parameters. Details are available in Chapter "Operation" - Extras/
Interface 92 and in the booklet or diskette about the interface-card.
The integration assistant can integrate
and configure both available and not
yet available modules.
Details are available in Chapter
"Operation" - Module/ Integrate
