13.2.3. IP54 terminating circuit
When installing a CANopen system, ensure that the terminating circuit of the data lines is correct. The circuit pre-
vents the occurrence of interference caused by signal reflection in the data lines. The trunk line must be terminated
at both ends with resistors of 120 Ω each and 1/4 W power loss.
13.3. Position of the DIP switches
The DIP switches are used to make field bus module settings.
NOTE!
Changes made to the switch settings only take effect after the field bus module has been reset. Set the DIP
switch through the film using a screwdriver (the film is very durable).
'ON' setting = DIP switch to the right

Field bus module address

13.3.1. Field bus module address: DIP switches 1 to 6
The address of the field bus module can be set on DIP switches 1 ... 6 in the range 0 ... 63.
If an address between 63 and 127 is needed, this can be set via the object Index 3000 / Subindex 0. Then the
address is stored on an EEPROM (non-volatile) and is activated when:
• All DIP switches from 1 to 6 are set to 'ON' (address 63).
• A restart is carried out.
