Meaning
Starting and canceling of the
output sequence.
Number of pulses that are output
at the DO digital output on
expiration of the on-delay.
The on-delay that can be assigned
parameters can be changed
before the start of the output
sequence:
Time period = Factor x 0.1 x
configured time period
Starting and canceling of the
output sequence.
Number of pulses that are output
at the DO digital output on
expiration of the on-delay.
Setpoint of the time period
You can set the ratio of the pulse
duration to the interpulse period
Value range
0 = SW_ENABLE cleared.
1 = SW_ENABLE set
0 → 1 = Start of the output
sequence; may be dependent on
the HW enable
0 to 65535
If the number of pulses is 0, the
2PULSE does not output any
pulses. The output sequence is
terminated with ERR_PULS = 1.
Factor: 0 to 255
Period duration:
> Pulse duration up to 65.535 s
If there is a period duration
> 65.535 s, it is set to 65.535 s.
If a period duration ≤ pulse
duration, it is set to a pulse
duration of + 0.2 ms (or pulse
duration + 1 ms).
0 = SW_ENABLE cleared.
1 = SW_ENABLE set
0 → 1 = Start of the output
sequence; may be dependent on
the HW enable
0 to 65535
If the number of pulses is 0, the
2PULSE does not output any
pulses. The output sequence is
terminated with ERR_PULS = 1.
With time base 0.1 ms:
2 to 65535
With time base 1 ms:
1 to 65535
0 to 255
E.g the value of 128 corresponds
to a ratio of 50:50.
