3.3 RS485 network/CANopen (JST PHD-8)
PD4-N in a network
Generally, up to 254 (RS485) or 127 (CANopen) Plug & Drive motors can be actuated
in a network from a PC or PLC.
The number of PD4-N controllers in an RS485 network is limited to 32 by the
hardware.
These network connections are set up via the RS485/CANopen interface.

CANopen
With the PD4-N it is also possible to control the motor via CANopen.
If you use the Plug & Drive motor with CANopen, you can use the additional safety
function of the separate logic supply: Even when the voltage supply of the PD4-N is
interrupted, the processor continues to be supplied with power via the communication
line and the position data cannot be lost so that the machine does not need to be
referenced after being switched on.
More detailed information on this can be found in the CANopen reference and in the
NanoCAN user manual.
CANopen connection
A suitable CAN interface adapter (e.g. USB adapter from IXXAT or PEAK) is required
for connecting with a PC.
