The following descriptions contain only device-specific functions. Please consult your PLC
description for general information on the CAN bus and system configuration.
11.1
Setting the baud rate
For the operation of the RESISTRON
®
Temperature Controller RES-5009, the CAN baud rate must be set cor-
rectly. The baud rate depends on the CAN bus network into which the controller is to be integrated.
The baud rate is set by means of four “BAUDRATE” DIP switches. The switches are read in once when the device
is started. It is not possible to change the baud rate during operation.
The switch position '-' means off.
“AutoBaud” is active for all switch combinations not listed.
The automatic baud rate detection "AutoBaud" only works if the controller is in a CAN network in which at least
two participants are already exchanging valid CAN messages.
As long as the correct baud rate has not been detected, the controller behaves passively on the CAN bus and
does not influence the existing communication.
The controller can only detect the baud rates listed above, other baud rates cannot be detected.
CAUTION
If the baud rate in the CAN network is changed during operation, the controller must be switched
off and on again so that the "AutoBaud" function is active again.
CAUTION
When baud rate detection "AutoBaud" is active, the ERR LED (red) and RUN LED (green) flicker
alternately.
