LOGO! without display ("LOGO! Pure")

Operating characteristics

LOGO! is ready for operation when power is switched on. Switching off a LOGO! without display is equivalent to disconnecting the power supply, e.g. as if you were removing the plug.

The circuit program of LOGO!...o versions cannot be started 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 LOGO! or on the inserted memory card or combined memory/battery 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 memory card or combined memory/battery card is automatically copied to 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 LOGO! (Page 315), you can download the circuit program to LOGO! and start it by means of LOGO!Soft Comfort PC software.

Operating status indication

Operating states, e.g. Power On, RUN and STOP are indicated 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 provides an online test for reading the current data of all functions while the system is in RUN.

If your LOGO! without display holds a protected memory card or combined memory/battery card, you cannot read the current data unless you enter the correct password (Page 305) for the circuit program. The circuit program is otherwise deleted from LOGO! memory when you remove the memory card or combined memory/battery card to connect the PC cable.

Deleting the circuit program

Use LOGO!Soft Comfort to delete the circuit program and password if a password exists.
