• 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 following 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 cannot be used in any other application.

Function
7SEG(214) reads the source data, converts it to 7-segment display data, and outputs that data (as left-
most 4 digits D0 to D3, rightmost 4 digits D0 to D3, latch output signals LE0 to LE3) to the 7-segment
display connected to the output indicated by O. The value of C indicates the number of digits of source
data (either 4-digit or 8-digit) and the logic for the Input and Output Units.
7SEG(214) displays the 4-digit or 8-digit data in 12 cycles, and then starts over and continues display-
ing the data.
The One Round Flag (bit 08 of O when converting 4 digits, bit 12 of O when converting 8 digits) is
turned ON for one cycle in every 12 cycles after 7SEG(214) has turned ON each of the latch output sig-
nals.
