12.7 Special Functions
12.7.1 Counter Function
The internal counter counts the input pulses received from 'digital input' and
compares it with the setting value of 'Counter middle value' or 'Counter target
value'.
The 'Counter middle value arrival' or 'Counter target value arrival' output signal
will be indicated via DO1 or Relay 1 output when the counter value equals to
that of setting value.
The counter is cleared and the DO1 or Relay 1 output signal is reset by a valid
edge signal of another digital input defined as 'Counter reset'.

Example:
X1 input is defined as '39: Counter input'.
X2 input is defined as '40: Counter reset'.
The wiring is shown as the figure below:
Fig. 12-30: Digital input configuration
Connected K1 to X1, and set [E1.00] = '39: Counter input'.
Connected K2 to X2, and set [E1.01] = '40: Counter reset'.
