Input Wiring
[Input interruption function (with delay function)]
Interruption routines can be processed
preferentially by external signals with the minimum
ON or OFF width of 5
µ
s (X000 to X005).
(Timer interruption and high-speed counter
interruption functions are also provided.)
→ Refer to Chapter 10 "Input Wiring
Procedures (Input Interruption and Pulse
Catch)" in this manual and Programming
Manual.
[Pulse output function]
1) When output terminals in the transistor
output type main unit are used, pulses (open
collector outputs) of up to 100 kHz can be
output simultaneously to three axes (Y000,
Y001 and Y002).
2) When two high-speed output special adapters
FX
3U
-2HSY-ADP are used, pulses (differential
line driver outputs) of up to 200 kHz can be
output simultaneously to four axes.
→ Refer to Positioning Control Edition.
[Various positioning instructions]
→ Refer to Positioning Control Edition.
3. Display functions (display module)
FX
3U
-7DM Display Module (option) can be
incorporated in the PLC.
The display module can be mounted on the panel
by using the display module holder (option).
[Monitor/test function]
Devices can be monitored and tested by
operating the buttons on the display module.
The button operations can be inhibited by the
user program.
[Message display function]
User messages can be displayed on the display
module by the user program.
[Other functions]
On the display module, you can set the time,
adjust the contrast and display the PLC version
and error codes.
