5-28 Advanced I/O Instructions
Advanced I/O instructions enable control, with a single instruction, of previously
complex operations involving external I/O devices (digital switches, 7-segment
displays, etc.).
There
are five advanced I/O instructions, as shown in the following table. All of
these are expansion instructions and must be assigned to function codes before
they can be used.
Name Mnemonic Function
7-SEGMENT DISPLAY OUTPUT 7SEG(––) BCD output to 7-segment dis-
play
DIGITAL SWITCH INPUT DSW(––) Data input from a digital switch
HEXADECIMAL KEY INPUT HKY(––) Hexadecimal input from 16-key
keypad
TEN-KEY INPUT TKY(––) BCD input from 10-key keypad
MATRIX INPUT MTR(––) Data input from an 8 x 8 matrix
Although TKY(––) is used only to simplify programming, the other advanced I/O
instructions can be used to shorten cycle time, reduce the need for Special I/O
Units, and reduce system cost. With the exception of TKY(––), however , the ad -
vanced
I/O instructions can only be used once each in the program and cannot
be used for I/O Units mounted to Slave Racks, where Special I/O Units must be
used.

C: Control data
000 to 007
O: Output word
IR, SR, AR, HR, LR
Limitations S and S+1 must be in the same data area.
Do not set C to values other than 000 to 007.
Overview When
the execution condition is OFF , 7SEG(––) is not executed. When the exe -
cution
condition is ON, 7SEG(––) reads the source data (either 4 or 8-digit), con -
verts
it to 7-segment display data, and outputs that data to the 7-segment display
connected to the output indicated by O.
The
value of C indicates the number of digits of source data and the logic for the
Input and Output Units, as shown in the following table.
