What does "BASP" mean?
In BASP mode (inhibit command output) all the digital outputs are
inhibited. BASP is deactivated by the CPU when the RUN state is
entered and activated upon transition to the STOP state. BASP is
activated in STARTUP and STOP.
If an automatic or manual warm restart is made prior to going into
RUN, then the BASP LED first goes off when the rest of the cycle
has been processed.
Exception: in test mode with multiprocessor operation the BASP is
not active - refer here to your system manual. Therefore, you
should never activate the test mode under running production
conditions, but only during the start-up phase.
Just in case you forget to connect the power supply of the monitor
input (load voltage monitoring), then the BASP LED is also enabled
and the CPU can very well be in RUN. This monitoring can also be
switched off. Please refer to your system manual for more
