16-Bit Counter C0-C79 - Delta CP2000 Series User Manual

16-bit counter C0-C79:

16-bit counter setting range: K0-K32,767. (when K0 and K1 are identical, the output contact will

immediately be On during the first count.)
The current counter value will be cleared from an ordinary counter when power is shut off to the

PLC.
If the MOV command or WPLSoft is used to transmit a value greater than the set value to the

C0 current value register, when the next X1 goes from Off→On, the C0 counter contact will
change to On, and the current value will change to the set value.
A counter's setting value may be directly set using a constant K or indirectly set using the value

in register D (not including special data registers D1000- D1199 or D2000 ~ D2799).
If the set value employs a constant K, it may only be a positive number; the set value may be

either a positive or a negative number if the value in data register D is used. The current
counter value will change from 32,767 to -32,768 as the count continues to accumulate.
Example
LD X0
RST C0
LD X1
CNT C0 K5
LD C0
OUT Y0
1. When X0=On and the RST command is
executed, the current value of C0 will
revert to 0, and the output contact will
revert to Off.
2. When X1 changes from Off→On, the
current value of the counter will execute
an increase (add one).
3. When the count of counter C0 reaches the
set value K5, the contact C0 will come On,
and the current value of C0＝ set value
=K5. Afterwards, signal C0 triggered by X1
cannot be received, and the current value
of C0 will remain K5.
