Vision™ OPLC™ V570-57-C30B, V570-57-T40B
CANbus
These controllers comprise a CANbus port. Use
this to create a decentralized control network
using one of the following CAN protocols:
CANopen: 127 controllers or external
devices
Unitronics' proprietary UniCAN: 60
controllers, (512 data bytes per scan)
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%, 121S, 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
