2.3.5.3.3.5 Terminating resistor
A terminating resistor for the CAN interface is already integrated in the IF option. A switch is used to switch the
terminating resistor on or off, but it is necessary to open the system unit for this purpose. A switched-on terminating
resistor is indicated by a yellow LED.
