Binary Output – OnOff Pulse (2-channel)
BO_Q250_P_2CHA
(SIMATIC Manager hardware catalog)
Parameters for control of a binary output (2-channel) with specified pulse length.
When the process value [BOValue] changes from
inactive
to
active
, the output
(n+1) is activated for the specified pulse length and then deactivated again.
When the process value [BOValue] changes from
active
to
inactive
, the output
(n) is activated for the specified pulse length and then deactivated again.
If the process value [BOValue] changes while a pulse is being generated, the
pulse will be
–
cancelled
and
–
the other output is activated after a delay [BreakTime] in accordance with the
new process value.
The S7 software provides a continuous output signal for the first channel, which
displays the status of the field device.
The S7 software does not send any pulse signals since the pulses are
generated by the TX-I/O module.
Each signal sent to the second channel is ignored.
Locking in the module makes it impossible to run a command on both channels at
the same time. However, we recommend the installation of an additional lock in the
switching cabinet. The switching contacts can be used for this purpose, for
example.
The TXM1.6R-M module enables local override. Press
the rocker switch of
either
of the two channels. The
following applies: pressure on…
...
middle
(hand): local override ON /
OFF; no change at the output. The
yellow LED of the channel lights while the override function is switched on
... + (up):
connected device on
... – (down):
connected device off
