MOTORTECH devices preset to 250 kbit/s

For communication via the CAN bus, it is mandatory that all connected devices use the same bit rate. MOTORTECH devices are usually delivered with a bit rate set to 250 kbit/s. Use this bit rate in the PowerView4 as well.

 

If the PowerView4 is connected to a CANOpen® network via the CAN bus interface CAN1, you can make the following settings for this network in the Communication Setup view:

PowerView4

Changing Node ID

The factory setting for the node ID on your PowerView4 is 66. Change the node ID as follows:

  1. You can set a node ID for your PowerView4 in the PowerView4 area using the arrow keys.
  2. Tap Save to confirm the setting of the node‑ID.

The changed node ID will be discarded if you tap Reset before saving or leave the Communication Setup view without saving.

Changing Bit Rate

Change the bit rate of the PowerView4 as follows:

  1. Select the desired bit rate in the PowerView4 area.
  2. Tap Save.

The changed bit rate will be discarded if you tap Reset before saving or leave the Communication Setup view without saving.

Other Devices

If supported by the respective device, you can use LSS commands to change the node ID and the bit rate of devices in the CAN bus on CAN1.

The following MOTORTECH device supports changing the node ID and bit rate via LSS commands:

Temperature module TempScan20 
  

LSS commands: Disconnect all other devices from the CAN bus!

When sending LSS commands, all devices connected to the CAN bus via CAN1 are addressed. In order to change the bit rate or the node ID of the desired device only, no other devices may be connected to the PowerView4 via CAN1.

   

LSS commands: Use identical bit rates!

LSS commands can only be received from another device in the CAN bus if the LSS manager (here: PowerView4) is set to the bit rate of the other device. If necessary, set the corresponding bit rate in the PowerView4 before sending the LSS command.

 

Changing Node ID

You can change the node ID of another device in the CANopen® network as follows:

  1. Make sure that the current bit rate of the other device is set in the PowerView4.
  2. Make sure that there is only the other device connected to the PowerView4 via CAN1.
  3. Set the node ID that the other device is to be given in the LSS Commands area.
  4. Tap Send Command.
  5. If you have changed the bit rate of the PowerView4 in step 1, set the PowerView4 back to the previous bit rate in the PowerView4 area, if required.

 

Changing Bit Rate

You can change the bit rate of another device in the CANopen® network as follows:

  1. Make sure that the current bit rate of the other device is set in the PowerView4.
  2. Make sure that there is only the other device connected to the PowerView4 via CAN1.
  3. Make sure that the current node ID of the other device is set in the LSS Commands area. Otherwise, it will be changed accordingly when the LSS command is sent.
  4. Select the bit rate that the other device is to be given.
  5. Tap Send Command.
  6. If you have changed the bit rate of the PowerView4 in step 1, set the PowerView4 back to the previous bit rate in the PowerView4 area, if required.
