4.2.1 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.
