2.8 Connect field bus
CANopen
Figure 22:
Connection of CANopen
The following CAN bus cable is recommended in line with the requirements
in ISO 11898:
•
UNITRONIC bus LD, Messrs. LAPPKABEL
•
2 x 2 x 0.22 mm²
•
Surge impedance: 100 – 120 Ohm
•
Effective capacitance: 800 Hz, max. 60 nF/km
To connect the CANopen field bus, follow the steps below:
▶
Insert the CAN bus cable's wires into the push-in terminals on the three-
pin FMC 1.5/3-ST-3.5 contact plug.
▶
Connect the contact plug to the X1 field bus interface on the gateway.
▶
You can use the X2 field bus interface on the gateway to connect addi-
tional field bus modules.
2.8.1 Maximum cable length
The maximum cable length for a CAN bus cable depends on the baud rate
being used. The following table provides an overview of the possible Baud
rates and the corresponding maximum cable lengths:
