Meaning
Starting and canceling of the
output sequence.
The value that is output in
frequency format on the digital
output DO.
The on-delay that has been
assigned parameters can be
changed before the start of the
output sequence:
On-delay = Factor x 0.1 x
configured on-delay
Starting and canceling of the
output sequence.
The value that is output in
frequency format on the digital
output DO.
The on-delay can be changed
before the start of the output
sequence.
Value range
0 = SW_ENABLE canceled
1 = SW_ENABLE set 0→1 = start
of output sequence; may be
dependent on the hardware
enable
Depending on the output format:
1 Hz: 0 ... 5000

S7 analog output:

0 to 27648
If you enter an output value >
5000 or 27648, the 2PULSE limits
this to 5000 or 27648.
0 to 255
If the on-delay <0.2 ms or if factor
= 0, the effective on-delay is = 0.
If there is an on-delay > 65.535 s,
the on-delay is limited to 65.535 s.
0 = SW_ENABLE canceled
1 = SW_ENABLE set 0→1 = start
