Programming LOGO!

3.7 Writing and starting the circuit program

Your circuit program is now named "ABC", and you are returned to the programming menu. To change the name of your circuit program, proceed in the same way.

Note

You can change the name of the circuit program only in programming mode. You can read the name both in programming and in parameter assignment mode.

3.7.5Password for circuit program protection

You can protect a circuit program from unauthorized access by assigning it a password.

You can only assign or deactivate a program password from a LOGO! Basic or from LOGO!Soft Comfort. You can only change a program password from a LOGO! Basic. If you have assigned a program password, and are using a LOGO! TD (version ES4 or later) together with a LOGO! Base Module (version ES4 or later), you must enter this password if you want to change LOGO! from RUN mode to STOP mode from the LOGO! TD. You can not stop the execution of the circuit program in LOGO! from the LOGO! TD without entering the password.

Note

This password protection function is only available in the LOGO! TD with version number ES4 or later. This function is only available under the following conditions:

•The version number of both the LOGO! Base Module and the LOGO! TD installed is at least ES4

•LOGO! is currently in RUN mode and you want to switch to STOP mode

There is only one circuit program protection password that you can assign for LOGO!. You can only assign it from the LOGO! Basic or from LOGO!Soft Comfort. To change LOGO! from RUN to STOP from the LOGO! TD, you must enter the password from the LOGO! TD as described below in the section "Changing LOGO! from RUN to STOP mode from the LOGO! TD".
