Setting the node ID and baud rate

In the converter you must set the node ID and the baud rate to permit communication.
CAUTION
Changes made to the node ID or baud rate only become effective after switching off and on
again. It is particularly important that any external 24 V supply is switched off.
Note that before turning off, you must save the changes using RAM -> ROM (
The currently active Node ID is displayed in parameter r8621.
Setting the node ID
You can define the node ID either using the DIP switch on the Control Unit, using parameter
p8620 or in STARTER in the screen form under "Control Unit/Communication/CAN" under
the CAN interface tab.
Valid node IDs:
Invalid node IDs:
When a valid node ID has been set using DIP switches, then this is always effective and
p8620 cannot be changed.
If you set all DIP switches to "OFF" (0) or "ON" (1), then the Node ID set in p8620 or
STARTER is effective.
The positions and settings of the DIP switches are described in Section Interfaces,
connectors, switches, control terminals, LEDs on the CU (Page 46).
Setting the data transmission rate
You can set the transmission rate in the range from 10 kbit/s ... 1 Mbit/s using parameter
p8622 or in the STARTER screen form "Control Unit/Communication/CAN" under the CAN
interface tab.
