Hold/Clear Remote Outputs
When the DeviceNet Section is used as a slave, pin 4 is used to set whether
to hold or clear remote outputs when a communications error occurs.
Note If the DeviceNet Section is used as a slave, the 7-segment display will show
"L9" when remote I/O communications stop.
Turn ON this switch to connect terminating resistance at each of the nodes on
the end of the DeviceNet network's trunk line. The status of this switch is
shown by the TER indicator.
Note This switch is set to OFF (terminating resistance not connected) at the factory.
Color stickers that match communications cable colors are attached to the
communications connectors. Match the colors when connecting communica-
tions cables to the connectors. These colors are given in the following table
Color
Black Power line, negative voltage (V–)
Blue Communications line, low (CAN L)
--- Shield
White Communications line, high (CAN H)
Red Power line, positive voltage (V+)
For details on communications specifications and wiring, refer to the
DeviceNet Operation Manual (W267).
Note Before connecting communications cables, turn OFF the NSJ Controller
power supply, all slave power supplies, and the communications power sup-
ply.
The touch panel is a color TFT high-luminance LCD screen or a color STN
LCD (NSJ5-SQ0@(B)-@@@ only). The touch switches on the front panel of
the Display Section are used to perform input operations.
Function
When a functional object is pressed, its function is performed.
performed
To ensure correct input operations, create touch switches so that they consist
of at least two switches horizontally and vertically.
(1) Press the touch switches with a pressure of 30 N max.
(2) Do not press the touch switches when the backlight is not lit or when there
is no display.
(3) Check system safety before pressing the touch switches.
(4) Inputs may not be recognized if the touch switches are pressed in rapid
succession. Check that one input operation has finished before perform-
ing the next one.
