FXCPU Structured Programming Manual
(Application Functions)
Program example
In this program, the number of times the bit data stored in a device specified in turns ON from OFF is
counted up (added by "1"). When the value stored in a device specified in reaches the value specified in
, a device specified in turns ON.
At the same time, the number of times the bit data stored in a device specified in turns ON from OFF is
counted down (subtracted by "1"). When the value stored in a device specified in becomes "0", a device
specified in turns ON.
1) Function without EN/ENO(CTUD)
2) Function with EN/ENO(CTUD_E)
