Program example
In this program, the number of times the bit data stored in a device specified in
counted, and a device specified in
becomes "0".
1) Function without EN/ENO(CTD)
[Structured ladder]

g_bool2
g_int1
[ST]
CTD_Instance(CD:=g_bool1,LOAD:=g_bool2,PV:=g_int1);
g_bool3:=CTD_Instance.Q;
g_int2:=CTD_Instance.CV;
2) Function with EN/ENO(CTD_E)
[Structured ladder]
M10
