■ Outputting the input (ON/OFF status) of a basic unit directly to an expan-
sion output unit
The ON/OFF status of a KV series basic unit is output to a KV-E16T(P) unit con-
nected next to the basic unit.
Coding
Description
• The LDA instruction transfers the input (ON/OFF status) of the KV basic unit to
the internal register using binary numbers.
• The STA instruction outputs the binary data in the internal register as the ON/
OFF status from the KV-E16T(P) (output unit).
➮ Refer to "1.3 Device Configuration" (p. 3-5) for relay number assignments.
Note 1: When "LDA 0004" and "STA 0604" are programmed in the above example,
the LDA instruction can transfer inputs 0100 through 0103 to the internal register;
however, the STA instruction cannot output data across the channels. As a result,
the ON/OFF status of inputs 0100 through 0103 cannot be output even if they are
fetched by the LDA instruction.
Note 2: Relays 0000 through 0415 are assigned as input relays, and 0500 through
0915 are assigned as output relays.
