ters (Page 252).
True / False When there is an edge change 0 → 1 a new pulse
sequence begins.
Digital input / output /
bit memory With the setting "True", the pulse sequence set in
the parameters runs precisely once after the RTU
STATUS_ERROR
starts up or after a new configuration has been
adopted.
With the setting "False" the output is never set.
100 .. 999999999 Pulse duration in milliseconds
0 .. 999999999 Pause between two pulses in milliseconds
If the number of pulses is > 1 or the Start value
"Pause" is selected, the Interpulse period must be ≥
100 ms.
1 .. 999999999 Specifies the number of pause/pulse cycles (pulse
sequence).

With "Pulse" the pulse sequence starts with a
"1" at the output.
With "Pause" the pulse sequence starts with a
"0" at the output.
With "Trigger", the pulse sequence ends as
soon as the "Trigger" input changes to 0 or the
configured number of cycles is reached.
With "Time" the pulse sequence ends when it
has run completely.
