Functionality
Similar to the TP
block, this is a pulse generator. In contrast to TP
, the output ET
is not provided for uTP
.
Enter the length of the pulse at input PT
. If input IN
is →turned on and during the length of the pulse, output Q
returns value TRUE
(or an equivalent). If input PT
is changed after input IN
has been turned on, the behavior of the block is affected.
This block receives the current system time from the runtime system. This time remains constant while the same task is executed. However, in case of different tasks, it is possible that a different system time is used when the belonging programs are executed (even if the different tasks have the same cycle time). |
The following illustration shows the behavior of uTP
:

See:
-
"Blocks for safe logic" whether this block is supported for developing safety-relevant applications.
-
"Highlighting safe logic in the FBD-editor" for the effects when using the block as a block for safe logic.
