Short description:

A function that delays the signal change with external change of the timer value.

 

Inputs (2):

no.	type	impulse	mark	notes
1	B	no	IN	Binary input no. 1
2	I	no	preset	Set timer value [ms]

 

Outputs (2):

no.	type	impulse	mark	notes
1	B	no	OUT	Binary output no. 1
2	I	no	time	Current timer value [ms]

 

Settings: none

Function operation:

The DELAY_B function delays the transfer of the signal change. When a high state is given to the IN input, the function starts a counter whose initial value is 0. When the counter reaches the value set by the user at the preset input, the OUT output shows a high state. If in the previous state the state at the OUT output was high, the appearance of a low state at the IN input causes the counter reset, and then the counter starts. When the counter reaches a user-defined value, the OUT state is low. The time output returns the current timer value.
