2. Overview and Operation
2.1 Use Examples for the KV-D20
This section includes examples of uses for the KV-D20.
As a handheld programmer
The KV-D20 allows you to change the KV series’ operating mode (RUN or PRO-
GRAM) or to change the preset values of timers and counters without using the
KV-P3E(01) handheld programmer.
As a digital switch
Various values can be input with the KV-D20. You can directly change the values
of desired devices without using ladder programs.
Moreover, the KV-D20 can be connected with a cable instead of the I/O unit, so
that the amount of wiring and I/O points can both be reduced.
As a display unit
The KV-D20 can display the number of products or the tact time. Since the KV-D20
can be connected with a cable instead of the I/O unit, the amount of wiring and I/O
points can both be reduced.
As a device to give instructions to workers
When using a rotating beacon, the occurrence of an error can be noted but the
contents of the error, such as a clogged workpiece, missing workpiece, or product
changeover, may often be unclear.
The KV-D20 features a user message function. By using the function, work effi-
ciency can be greatly improved.
A beep function is also available to indicate errors with sound.
