2. Set data
3. Applicable devices
S: This function is supported only in FX3U/FX3UC PLCs.
Explanation of function and operation
1. 16-bit operation (SEGL)
The 4-digit numeric value stored in is converted into BCD data, and each digit is output to the seven-segment
display unit with the BCD decoder by the time division method.
When using one set of 4 digits (n = K0 to K3)
→ For selection of "n", refer to Subsection 15.5.2.
1) Data and strobe signal
A 4-digit numeric value stored in is converted from binary into BCD, and each digit is output in turn from
to +3 by the time division method.
The strobe signal is output in turn from +4 to +7 by the time division method also to latch one set of
4-digit seven-segment display unit.
2) For , binary data ranging from 0 to 9999 is valid.
