2. Overview and Operation

KV-I/O monitor screen

Allows simultaneous monitoring of two channels (8 bits x 4) for the ON/OFF status

of the input (IN), output (OUT), and connection information (USE) of the KV series

I/O devices.

■

" represents the ON status, and "_" represents the OFF status.

Bits are assigned from right to left: bits 0 through 7 on "L" lines, and bits 8 through

15 on "H" lines.

Holding down the ▲ or ▼ key lets the screen scroll faster (turbo function). How-

ever, in the turbo mode, the screen does not show the ON/OFF status but shows

only device numbers.

Customized switches F1 through F4 and customized lamps 1 through 4 can be

used in all modes.

To lock the display screen, press the

and ▲ (▼) keys simultaneously for three

seconds to set/reset the key-lock function.

Refer to the table below for the information displayed on the KV-I/O monitor screen.

* The initial setting displays "RLY00000" (KV-40: "RLY00100") for "I/O-IN",

"RLY00500" for "I/O-OUT", and "DM1937" for "I/O-USE".

The relays for the expansion unit (RLY00100 to 00415, RLY00600 to 00915)

are displayed only when the corresponding expansion unit is connected.

• Press the ▲ or ▼ key to select the

device number (IN, OUT, or USE).
