How can ensure that the number key is only active when i press on it & the bit go false when i release the button. Can this be done? Please advise. I have tried looking for examples with momentary switch but that didn't work for me. Thank you in advance. Attachment number keypad LWE.png (91 Downloads)

Seems like it's not possible looking at this: https://support.industry.siemens.com/tf/ww/en/posts/logo-8-2/185641/?page=0&pageSize=10 However ixo65 seemed to have a work around.

If you have HTML programming skills you can do anything you want with it. But to answer your question (if I understand correctly) there is another possible solution.You can program it through the LOGO! program. See the attached file. Ι hope this helps you.

In the program suggestion is the password 618724. The ON parameter of the counter corresponds to the password, the OFF parameter is password + 1. The alarm system would be locked when entering 0 in the password entry field. Attachment Code_lock_V2.zip (110 Downloads)
