Trigger
•
True / False
•
Digital input /
output / bit
memory
•
STATUS_ERROR
When there is an edge change 0
→
1 the On delay is
started.
When there is an edge change 1
→
0 the Off delay is
started.
With the setting "True" the trigger is always active.
With the setting "False" the block is never processed.
Reset
•
True / False
•
Digital input /
output / bit
memory
•
STATUS_ERROR
When there is an edge change 0
→
1 On delay is
stopped and the output is set to 0. As long as the input is
set to 0, the value of "Trigger" is ignored.
When there is an edge change 1
→
0 the block can be
processed again.
With the setting "True" an edge change 0
→
1 at "Trigger"
is permanently ignored. The "Off delay " function is there-
fore also turned off.
With the setting "False" the input is never active.
Function parameters
On delay (ms)
100 .. 999999999
Minimum time in the clock cycle during which the output
= 1.
On delay max.
(ms)
100 .. 999999999
Maximum time in the clock cycle during which the output
= 1.
Off delay min
(ms)
100 .. 999999999
Minimum time in the clock cycle during which the output
= 0.
Off delay max.
(ms)
100 .. 999999999
Maximum time in the clock cycle during which the output
= 0.
Output parameters
Output

Tag in which the pulses generated by the block are out-
put.

Pulse sequence
Function
A maximum of 2 blocks of this type can be created.
A repetitive pulse sequence with configurable duration of the individual high and low phases
is sent to the output. The phase position of the first phase is always high. If the pulse
sequence is to begin with the phase position "Low", the first phase can also be configured
with the duration 0 or the output can be negated.
