LOGO! Base Module operating states

LOGO! Base Modules (LOGO! Basic or LOGO! Pure) have two operating states: STOP and RUN.

STOP

•The display shows: 'No Program' (not LOGO!...o)

•Switching LOGO! to programming mode (not LOGO!...o)

•LED is red (only LOGO!...o)

Action of LOGO!:

•The input data is not read.

•The circuit program is not executed.

•The relay contacts are permanently open or the solid-state outputs are switched off.

RUN

•Display: Screen mask for monitoring I/O and messages (after START in the main menu) (not LOGO!...o or LOGO!...E)

•Display: Screen mask for monitoring I/O and messages (after START in the main menu) or for the parameter assignment menu

(only LOGO!...E)

•Switching LOGO! to parameter assignment mode (not LOGO!...o or LOGO!...E)

•LED is green (only LOGO!...o)

Action of LOGO!:

•LOGO! reads the status of the inputs.

•LOGO! uses the circuit program to calculate the status of the outputs.

•LOGO! switches the relay/solid-state outputs on or off.

Note

After switching the power on, the system briefly switches through the outputs on the LOGO 24/24o or LOGO! 24C/24Co. With an open circuit, a voltage of > 8 V can occur for up to approximately 100 ms; when loaded, this time reduces to a matter of microseconds.
