Operating status indication
Operating states, e.g. Power On, RUN and STOP are indi-
cated by an LED on the front hood.
Red LED: Power On/STOP
Green LED: Power On/RUN
The red LED is lit after Power On and in all LOGO! states
other than RUN. The green LED is lit when LOGO! is in
RUN mode.
Reading current data
LOGO!Soft Comfort (see Chapter 7) provides an online test
for reading the current data of all functions while the sys-
tem is in RUN.
If your LOGO! without display holds a protected program
module (card), you can not read the current data unless
you enter the correct password for your the circuit program.
The circuit program is otherwise deleted from LOGO! me-
mory when you remove the program module (card) to con-
nect the PC cable, for example (see Chapter 6.1).
