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).
