Figure 11: Switching element on the DMI: Pushbutton fieldbus
controlled via level of the output data
a The pulse on the “ON“ pushbutton on location switches the
motor on.
b The switch on via the fieldbus has no externally visible effects
as the motor is already switched on.
c The switch-off via the fieldbus causes the motor to switch off.
d The switch-on signal on the fieldbus causes the motor to switch
on.
e The switch off button has the effect of switching off the motor.
f The switch off via the fieldbus does not have an effect as the
motor is already switched off. It is however a precondition so
that the motor can again be started via the fieldbus.
g The motor is restarted via the fieldbus.
h The “ON” pulse on the DMI has no effect as the motor is
already switched on.
i The pulse from the “OFF” pushbutton has the effect of
switching off the motor even though a High level is still present
on the fieldbus. The switch off takes priority here for safety
reasons.
j The switch off via the fieldbus does not have an effect as the
motor is already switched off.
