What is meant by: ”LOGO! is in RUN”?
In RUN mode, LOGO! executes the circuit program. To do
so, LOGO! first reads the status at the inputs, determines
the status of the outputs by means of the user program,
and switches these on or off according to your settings.
This is how LOGO! indicates the I/O status:
Q:
0.. 123456789
1..0123456
Input/output status is ’1’:
inverted
Input/output status is ’0’:
not inverted
I:
In this example, only the inputs I1, I15, Q8 and Q12 are set
“high“.
