4.8.2
CAN Bus Termination in “CAN-M” Supervisor Control (Master) Network
The CAN bus must be terminated at both ends by a termination resistor of 120
Ω
, typically. Depending
on utilization of the controller, individual CAN bus termination settings must be performed.
Using DIP switch JP1A [1], the controller-internal bus termination resistor can be activated/deactivated.
By default, bus termination is “OFF”, nevertheless, the bus is not terminated.

4.8.3
CAN Bus Autobitrate in “CAN-M” Supervisor Control (Master) Network
Using DIP switch JP1A [2], autobitrate can be activated/deactivated. By default, autobitrate is “OFF”.

4.8.4
CAN Bus Termination in “CAN-S” Slave Network
The CAN bus must be terminated at both ends by a termination resistor of 120
Ω
, typically. Depending
on utilization of the controller, individual CAN bus termination settings must be performed.
Using DIP switch JP1 [8], the controller-internal bus termination resistor can be activated/deactivated.
By default, bus termination is “OFF”, nevertheless, the bus is not terminated.
