Certain controllers comprise a CANbus port. Use
this to create a decentralized control network of
up to 63 controllers using Unitronics’ proprietary
CANbus protocol.
The CANbus port is galvanically isolated.
CANbus Wiring
Use twisted-pair cable. DeviceNet® thick
shielded twisted pair cable is recommended.
Network terminators: These are supplied with the
controller. Place terminators at each end of the
CANbus network.
Resistance must be set to 1%, 121Ω, 1/4W.
Connect ground signal to the earth at only one
point, near the power supply.
The network power supply need not be at the
end of the network
