Handling the Settings
Device node
Possible settings:
1
...
30
Default setting:
1
Belongs to: Interface cards
Explanation: defines the device node (or address) of the
device in order to distinct between multiple devices in
a network and to address it correctly. Up to 30 devices
can be controlled from one PC. Within a bus system like
CAN or GPIB, every address must only be given once.
CAN Baud rate
Possible settings:
10kBd
,
20KBd
,
50kBd
,
100kBd
,
125kBd
,
250kBd
,
500kBd
,
1MBd
Default setting:
100kBd
Belongs to: CAN interface card IF-C1
Explanation: determines the transmission speed of the
CAN bus messages. If you connect the CAN card to an
existing network, you got to set the same baudrate here
as the bus is using, becaus any device in a bus has to
use the same bus speed.
CAN ID System
(available since firmware 5.01)
Possible settings:
normal, Vector
Default setting:
normal
Belongs to: CAN interface card IF-C1
Explanation: with this, the user selects whether to use
the
normal
CAN ID system with 2 IDs per unit or the new
Vector
compatible CAN ID system with 3 IDs per unit. With
setting
normal
, the two IDs per unit build from the
Device
node
and the
Relocatable ID
(see external interface cards
manual for calculation scheme). With setting
Vector
, the
device will be assigned three CAN IDs, starting from the
base ID (see below), which is adjustable in steps of four
withing the whole ID range (11 bits, 0...2047). An addi-
tional ID is assigned as broadcast ID, which is seperate
from the three base IDs.
Note: depending on the setting being
normal
or
Vector
,
subsequent parameters will change.
CAN Relocatable ID
Possible settings:
0...31
Default setting:
0
Belongs to: CAN interface card IF-C1
Explanation: this determines the relocatable address seg-
ment in which the CAN IDs of the device are located. For
further information refer to basic CAN topology datash-
eets. Example: if the electronic load has to be assigned
to address 5 by certain reasons and this would collide
with another bus member with the same address, you can
move the address to another segment by defining the RID
(short for relocatable ID), so that no collision can occur.
Hence there are, theoretically, 32 x 30 possible device
nodes (with two IDs each) available when using CAN.
CAN Base ID
(available since firmware 5.01)
Possible settings:
0x000 (0000)
...
0x7FC (2044)
Default setting:
0x000 (0000)
Belongs to: CAN interface card IF-C1
Explanation: this adjusts the base ID for the CAN ID sys-
tem which uses three IDs (see above at CAN ID System).
With the three IDs per unit, the system is compatible to
Vector software and the so-called CAN databases (*.dbc).
The base ID is adjustable in steps of four. Also see the
further documentation for the Vector system, which is
included with the databases.
Note: this setting is only availabe, if
CAN ID System:
Vector
has been selected (see above).
CAN Broadcast ID
(available since firmware 5.01)
Possible settings:
0x000 (0000)
...
0x7FF (2047)
Default setting:
0x7FF (2047)
Belongs to: CAN interface card IF-C1
Explanation: the broadcast ID is an additonal ID of the
Vector ID system. It is generally used to send broad-
castmessages to multiple bus members at once. Those
units, when addressed by this ID will act the same time,
executing the same command, like setting current. With
this ID, only settings or values can be sent and nothing
can be queried.
Note: this setting is only availabe, if
CAN ID System:
Vector
has been selected (see above).
CAN Bus terminate
Possible settings:
yes
,
no
Default setting:
yes
(since firmware 5.01), else
no
Belongs to: CAN interface card IF-C1
Explanation: defines, if the bus termination resistor on the
CAN interface card is active or not. This is only required
if the device is at the end of the CAN bus. By setting this
parameter to
yes
the resistor is activated,
no
deactivates
it. In case you don‘t want to use this feature and instead
want to install a custom resistor for bus termination, make
sure that this setting is set to
no
.
RS232 Baud rate
Possible settings:
9600 Bd
,
19200 Bd
,
38400 Bd
,
57600 Bd
Default setting:
57600 Bd
Belongs to: RS232 interface card IF-R1
Explanation: determines the baudrate (transmission
speed) of the serial data transmission when using the
serial RS232 interface card IF-R1. Make sure, that the
other end of the serial connection operates at the same
baudrate.
