LOGO! without display

Creating a circuit program without operator panel

There are two ways to create a circuit program for a LOGO!
without display:
S
You create the circuit program with LOGO!Soft Comfort
on your PC and then download it to the LOGO!
(see Chapter 7).
S
You download the circuit program from a LOGO! pro-
gram module (card) to your LOGO! without display
(see Chapter 6).

Operating characteristics

LOGO! is ready for operation when power is switched on.
Switching off a LOGO! without display is equivalent to dis-
connecting the power supply, e.g. as if you were removing
the plug.
The circuit program of LOGO!...o versions can not be star-
ted or stopped by means of buttons. This is why the
LOGO!...o versions have other startup characteristics:

Startup characteristics

If there is no circuit program in the LOGO! or on the in-
serted program module (card), LOGO! remains in STOP.
If there is a valid circuit program in LOGO! memory, the
LOGO! automatically switches from STOP to RUN when
power is switched on.
The circuit program on an inserted program module (card)
is automatically copied to the LOGO!, immediately after
power is switched on. The existing circuit program in
LOGO! memory is overwritten. The system automatically
changes from STOP to RUN.
Provided the PC cable is connected to the LOGO!, you can
download the circuit program to LOGO! and start it by
means of the LOGO!Soft Comfort PC software
(see Chapter 7.1).
