the device on the DIN rail. The ground of the CAN bus interface is connected to

earth via a 1 MΩresistor and a 10 nF capacitor.

For best noise immunity results, the shields of the CAN cables have to be

grounded.

2.3.3 DIN rail bus and TBUS plug

The CAN-CR200 and CAN-CR210/FO have a DIN rail bus. With this interface the

device can be connected to other CAN-CR200 or CAN-CR210/FO devices. Using

this feature you have the possibility to realize a star topology with up to 240 CAN

connections.

For the DIN rail bus so called TBUS plugs are necessary. This plugs were pressed

into the DIN rail. More detailed information can be read in chapter 4.2

The signals of the DIN rail bus are described in Table 2-5

2.4 CAN bus termination

The CAN-Repeater offers the possibility to add bus termination resistors to each

CAN network connected to the device. This feature is realized with a DIP switch

for each CAN channel. For more details please refer to chapter 3.1.

As an accessory a bus termination resistor is available as a feed through connect-

or at IXXAT (ordering number 1.04.0075.03000).

Configuration

3Configuration

To operate the CAN-Repeater, no software installation is required.

Before you can use the CAN-Repeater the internal DIP switches S301, S302,

CAN1, CAN2 and CAN3 has to be set according to the CAN network configura-

tion.

In Picture 3-1 the positions of the DIP switches of the CAN-CR200 are shown.

The DIP-switches of CAN-CR210/FO and CAN-CR220 are nearly at the same posi-

tion.

Configuration

3.1 Configuration of the bus termination resistors

For each CAN circuit a bus termination resistor can be activated /deactivated by a

DIP switch. Always both positions should be set to ON / OFF.

CAN1 CAN2 CAN3

Default OFF (deactivated) OFF (deactivated) ON (activated)

Table 3-1 Configuration of the bus termination resistors

The bus termination resistors should be activated if the CAN-Repeater is the first

or the last device in the network. The termination resistor value of the total net-

work should be about 60 Ohm (120 Ohm at both ends of the network).

If the bus termination is not correct, transmission problems could happen.

3.2 Configuration of the baudrate

With DIP switch S301 the baudrate of the CAN network is defined. This setting is

necessary, because the internal logic has to detect dominant-lock states (domi-

nant level on CAN bus exceeds the maximum allowed duration).

S301-1

S301-2

S301-3 S301-4 Remark

ON OFF OFF OFF Baudrate between 5 kBd and 100 kBd

OFF ON OFF OFF Baudrate between 100 kBd and 500 kBd

OFF OFF ON OFF Baudrate equal or above 500 kBd

(Default)

Table 3-2 Configuration of the baudrate

All combinations not listed in the table aren’t allowed. If such a combination is

set, malfunction of the CAN-Repeater could happen.

Configuration

3.3 Configuration of the lock time

With DIP switch S302 the lock time of the CAN-Repeater is defined. This time is

used to avoid bit errors created by the device itself in a result of the signal propa-

gation delay. Such an error could be a short dominant level inside of a recessive

bit, which could cause bit errors at other CAN nodes (depending on the sampling

point).

The setting of the lock time has to be done according to the baudrate and the

capacitive load of the network.

Table 3-3 Configuration of the lock time

For reference values the following settings can be taken:

-for networks with less than 32 nodes the minimum lock time should

be about 300 ns

-for networks between 32 and 64 nodes a minimum lock time of 500 ns

should be used

-for networks with more the 64 nodes a minimum lock time of 1 µs should be

used, but with this setting the maximum baudrate is limited to 500 kBd.

Installation

4Installation

To operate the CAN-Repeater, no software installation is required.

Before you use the CAN-Repeater following points have to be paid attention:

-configuration of the bus termination

-configuration of the baudrate

-configuration of the lock time

More detailed information to these points can be found in chapter 3.

4.1 Mounting a single CAN-Repeater

Prior to mounting the device it has to be assured, that the device is not

connected to power.

In Picture 4-1 mounting of a CAN-CR220 is shown.

Installation

4.2 Mounting with DIN rail bus support

CAN-CR200 and CAN-CR210/FO support a DIN rail bus extension possibility.

This feature gives you an easy possibility creating a star topology.

ATTENTION: The usage of the DIN rail bus is specific for IXXAT devices. If

another DIN rail bus is used, this one must not be connect-

ed to the IXXAT DIN rail bus.

If this is not considered, damages at the connected devices

could happen!

Prior to the connection of a device to the DIN rail, the TBUS plug has to be

mounted on the DIN rail. The orientation of the plug has to adapted to the de-

sired device installation position

Picture 4-2 TBUS plug and DIN rail

If the guide bar is like in Picture 4-2 below the power connector of the CAN-

Repeater is above.

Installation

The interconnection of two TBUS plugs can be achieved by mounting the plugs

and afterwards were moved together, as shown in Picture 4-3.

Picture 4-3 Mounting of TBUS plugs

Now the CAN-Repeater CAN-CR200 and/or CAN-CR210/FO can be mounted.

The package of the CAN-CR200 and CAN-CR210/FO has an opening for the TBUS

plug in the area of the DIN rail, see Picture 4-4 . While the devices are attached to

the DIN rail, a correct mounting to the TBUS plug has to be observed. The guide

bar of the plug has to mate into the slot in the package.

7.3 EMI Hints

The CAN-Repeater is a Class A device. This means, that it is tested and designed

for industrial use and complies to this requirements.

If the device is used in an office or living area, in extreme cases radio interferences

could happen.

To guarantee a correct function of the CAN-Repeater some EMI points have to be

paid attention:

•the DIN rail have to be connected to earth

•the CAN cable has to be shielded

•the shield of the CAN cable has to be connected to the Sub-D9 and has to be

connected on the other device.

If there are still problems while the CAN-Repeater is switched on, the distance

between a source of interference (eg. motors, frequency inverter) or a drain of

interference and the device should be enlarged.
