Figure 40 below shows Eltorque actuators that are connected directly to a
customer specific PLC, PC or other control unit. In addition, Eltorque actuators
support digital and analog connections. On system level, the PLC, PC or
Controller must be compliant with Eltorque communication protocol according to
Eltorque System Integrators Manual CANopen Interface.

System (IAS or ICS)
The total number of nodes in a ring configuration is less than with a bus
configuration.
Note! For the ring configuration, Eltorque recommends no more than 75 nodes on 500
m Hybrid marine cable.
Table 19: Cable requirements and recommendations for Dual CAN system
Maximum 500 m/1650 ft.
For other cable lengths and number of nodes contact your local
Eltorque representative and we will help you to get the correct set-up.
For Hybrid Marine cable nominal 120 Ω.
Both Dual CAN inputs on the actuator must be impedance matched to
the characteristic impedance of the cable used. When projected by
Eltorque this is handled by our project personnel.
