Connecting
Communications
Cables
Connect the Master Unit and T-branch Taps, T-branch Taps and T-branch
Taps, and T-branch Taps and Slaves using Thin DeviceNet Communications
Cables, as shown in the following diagram.
Use the following procedure to connect the cables. Refer to 5-2 Connecting
Communications Cables to General-purpose Slaves for details.
1,2,3... 1. Prepare the communications cables and attach the connectors to the ca-
bles.
2. Connect the communications cable connectors to the node connectors on
the Master Unit, T-branch Taps, and Slaves.
Wiring the I/O Power
Supply
If required, an I/O power supply for I/O devices is connected to the Remote
I/O Terminals. Connect M3 crimp terminals to the power lines and then con-
nect them to the terminal block.
Wiring I/O Wire the I/O to the Remote I/O Terminals.
Connect M3 crimp terminals to the signal lines and then connect them to the
terminal block.
When a Terminating Resistor is required, connect it to the
final T-branch Tap in the Network. The T-branch Tap must
be no further than 6 m from the final node.
