7SEG --- Converts the source data (either 4-digit or 8-digit BCD) to 7-seg-
ment display data, and outputs that data to the specified output
word.
O: Output Word (Data and Latch Outputs)
Specify the output word allocated to the Output Unit and con-
nect the 7-segment display to the Output Unit as shown in the
following diagram.
• Converting 4 digits
• Converting 8 digits
C: Control Data
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 fol-
lowing table. (The logic refers to the transistor output’s NPN or
PNP logic.)
D: System Word
Specifies a work word used by the instruction. This word can-
not be used in any other application.
