9. Common Items and Others
8.2 Connection of Communication Cable Connector
Connect the communication cable in accordance with the connector table below.
Pin No. Cable wire color Signal name Description
1 Black V- Network power supply -
2 Blue CAN_L Signal wire, differential -
3 Shield Drain Drain (shield)
4 White CAN_H Signal wire, differential +
5 Red V+ Network power supply +
Color-coded seals corresponding to the cable wire colors shown in the table above are attached on the
supplied cable-end connector.
8.3 Power Supply Connection and Terminal Resistor
8.3.1 Power Supply Connection
The DeviceNet system supplies power to the network.
The supply voltage is 24 VDC, which is applied between the terminals for red (V+) and black (V-) wires in
the main line (5-wire cable).
Use a dedicated power tap or T-junction tap to connect the power supply directly to the communication
cable connector.
8.3.2 Terminal Resistor
A terminal resistor must be connected on both ends of the main DeviceNet line.
X-SEL, RCS-C and E-Con controllers have no built-in terminal resistors.
To connect a terminal resistor, prepare a dedicated terminal-block type terminal resistor (121
: r 1%, 1/4
W) or terminal resistor with T-junction tap (121 : r 1%, 1/4 W), or other resistor of equivalent specification,
and connect it directly to the communication cable connector.
(Note) For details, refer to the operation manual for the master unit.
8.4 Useful Functions You Should Know When Adjusting an X-SEL Controller
(1) In the case of an X-SEL K-type controller in which a standard or expansion I/O board is installed, the
X-SEL controller can be started on its own without connecting a 24-VDC I/O power supply.
(2) If a DeviceNet board is installed, the X-SEL controller can be started on its own before network
connection is established.
In either case, the applicable parameters (I/O Parameter Nos. 10 to 13) must be set to “0: Do not monitor.”
(Note) After the necessary operation or adjustment is completed, be sure to reset the parameters to their
original settings. If the parameters are not reset, error check will not be performed for the board in
each applicable slot.
