Sequential controls
Sequential control is the control of
a sequence of operations in
individual steps. Switching from
one step to the
following step is controlled by the
control program in accordance with
the “step enabling conditions”. The
main property of the sequential
control is that it can clearly assign
individual steps to technological
procedures with respect to time and
function. Consequently, distinction is
made between “time-oriented” and
“process-oriented” sequence control.
Positioning control
technology simulator
Pieces of wood are cut true to
dimensions on a saw table. For this
purpose a stop is to be positioned
from a control console with the help
of an electric motor.
The movement of the stop is
measured with a shaft-angle
encoder. Limit switches are located
at the end position of the spindle,
which are to prevent the stop from
entering the restricted area. Prior to
restart and cold restart of the
installation, the reference point is to
be approached. The spindle drive
can be controlled in clockwise or
Two-door access control

technology simulator
A dust-free room can be entered or
left only through an air-lock with two
automatically opening and closing
doors. Light barriers monitor the
entrances. In the case of an
emergency the air-lock room can be
opened or closed from within using
additional door openers.
Limit switches indicate the
corresponding positions of the
doors.
All operating states are to be
indicated via LEDs.
