Hi,

in your example the Softkey will only do something if you aktivate I3 first. Softwarekey requires a signal HIGH or LOW in front, if you then change the status of the softkey to "ON", then it switches the signal in fromt of it.

Check my example to get some experiances.

Hope it helps

Why block B325 Softkey is shows as “?N7” ?

What does it mean??

In the Logo software problems of various kinds can occur when the block numbers are higher than 200.
Remedy to your problem could create the following:
Replace a simple block as an AND or an OR block with small number. Only replace, not delete. This small number is free again.
Now delete the block B325 and add a new softkey. This now gets the free, small number.

This is your own experience or generally known information that blocks higher than 200 can do problems? I am not sure that this is in Logo! manual.

That is not in the manual, but in the Siemens technical forum.

There are various posts both in the german and in the english part of the forum.

Hi,

the block number was an issue at the beginning of LOGO! 8. I use LOGO! 8 at the beginning and with the todays LOGO! I never had this again.
