Can the CAN Bus Controller be mounted on a chassis?
Yes, the CAN Bus Controller is designed to be screwed onto the chassis in place of the left side panel.
Does the CAN Bus Controller come with a terminal block?
No, the terminal block for the CAN Bus Controller must be ordered separately. Compatible terminal blocks include models 7TB712.9, 7TB712.91, 7TB712:90-02, and 7TB712:91-02.
What type of diagnostic indicators does the CAN Bus Controller have?
The controller is equipped with diagnostic LEDs that indicate various operational states such as reset, start-up phase, normal operation, and errors.
How is the node number and transmission speed set on the CAN Bus Controller?
The node number and transmission speed are set using two switches on the controller. Special functions are available when the node number is set to 0, as the controller then uses operational parameters stored in the internal S-EEPROM.
What is the maximum transmission speed of the CAN Bus Controller?
The maximum transmission speed of the CAN Bus Controller is 500 kbauds.
How does the CAN Bus Controller handle termination resistance?
The controller has an integrated bus termination resistor, which can be activated by connecting a jumper between pins 1 and 2.
What is the maximum distance for the CAN Bus Controller's communication interface?
The maximum distance for the CAN communication interface is 1000 meters.
How does the CAN Bus Controller indicate a power overload?
The controller indicates a power overload by a flashing orange LED with a double pulse, suggesting that the total power of the modules exceeds the controller's supply capacity.
Is the CAN Bus Controller certified for safety and compliance?
At the time of the manual's publication, the CAN Bus Controller was in preparation for C-UL-US certification.
