Tab. 12-11: Counter function
'DO1 output' or 'Relay 1 output' signal and status are as below:
[E2.01] / [E2.15] = '16: Counter target value arrival'
●
When the internal counter receives from 'X1 input' the number of input pulse,
which equals to [E2.81] 'Counter target value'.
[E2.01] / [E2.15] = '17: Counter middle value arrival'
●
When the internal counter receives from 'X1 input' the number of input pulse,
which equals to [E2.80] 'Counter middle value'.
The signal is reset by the next valid edge signal of 'X2 input' which is defined as
'40: Counter reset'.
Example:
[E2.80] = 5, [E2.81] = 8
The output behavior is described as below:
Fig. 12-31: Output behavior
If the setting of any parameter E2.80, E2.81 and / or the status of
●
the defined digital inputs is changed, the counter value will be re-
set and the digital outputs will be inactive immediately.
The allowed maximum digital input frequency is 50 Hz and the al-
●
lowed minimum pulse width (both active and inactive) is higher
than 8 ms.
