Processing details
The 4-digit numeric value stored in (s) 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. For (s), binary data ranging from 0 to 9999 is valid.
Set the parameters (n) as follows according to the positive/negative logic of the PLC and the positive/negative logic of the
seven-segment display module.
