Part III FP Instructions
F91_SEGT
16-bit data 7-segment decode
This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which
is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the
"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears
under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming
area to open the list of recently used elements.

Variable Data type Function
s ANY16 16-bit area or equivalent constant to be converted to
7-segment indication (source)
d ANY32 32-bit area for storing 4-digit data for 7-segment indication
(destination)
For Relay T/C Register Constant
s WX WY WR WL SV EV DT LD FL dec. or hex.
d - DWY DWR DWL DSV DEV DDT DLD DFL -
Description
Converts the 16-bit equivalent constant or 16-bit data specified by s to 4-digit data for 7-segment
indication if the trigger EN is in the ON-state. The converted data is stored in the area starting with
the 16-bit area specified by d. The data for 7-segment indication occupies 8 bits (1 byte) to express
1 digit.
