If Terminating Resistors are connected to T-branch Taps, connect to the T-branch Tap furthest
from the power supply. The T-branch Tap, however, must be within 6 m of the furthest node.

If Terminal-block Terminating Resistors are used, the Terminating Resistor must be con-
nected to the end of a cable within 1 m from the furthest node.
Use the following procedure to connect the cables. Refer to 4-2 Connecting
Communications Cables to General-purpose Slaves for details.
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.
Most nodes on the network require an internal power supply in addition to the
communications power supply to operate the device. Supply internal power to
all nodes except for the Master Unit and C200H I/O Link Unit. Connect M3
crimp terminals to the power lines and then connect them to the terminal
block.
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 connect
them to the terminal block.
Connect M3 crimp terminals to the signal lines of Remote I/O Terminals and
Temperature Input Terminals and then connect them to the terminal block.
