I/O Modules 5-5
Input/Output Modules
Bus Wiring The CAN 16-I/O Modules and the Motion Coordinator are connected together on a
network which matches the physical specification of DeviceNet running at
500kHz. The network is of a linear bus topology. That is the devices are daisy-
chained together with spurs from the chain. The total length is allowed to be up
to 100m, with drop lines or spurs of up to 6m in length. At both ends of the net-
work, 120 Ohm terminating resistors are required between the CAN_H and CAN_L
connections. The resistor should be 1/4 watt, 1% metal film.
The cable required consists of:
Blue/White 24AWG data twisted pair
+ Red/Black 22AWG DC power twisted pair
+ Screen
A suitable type is Belden 3084A.
The CAN 16-I/O modules are powered from the network. The 24 volts supply for
the network must be externally connected. The
Motion Coordinator does NOT
provide the network power. In many installations the power supply for the
Motion Coordinator will also provide the network power.
Note:
It is recommended that you use a separate power supply from that used to
power the I/O to power the network as switching noise from the I/O devices
may be carried into the network.
