S7-1200 PLC error code 260001...

[Mas01]

Hi, It's a been a while since I last used this forum since the system I developed was delivered about a year ago now.
This is the first time I've got a problem report from the user. When he logs on with ADMIN account, he sees this message for a few seconds then it goes back to the login screen.

No idea why this should happen now, since it's been used regularly since it was delivered.

I was going to suggest power down/up and see if this fixes it (might seem a cop-out from the user's POV, but it might work?).
Has anyone seen this code 260001 before?
Where can I find a table of the error codes? Thanks in advance.

If a user enters an incorrect password three times consecutively, the system automatically moves that user into an "Unauthorized" group. In this state, the user can still attempt to log in, but they will have no access rights, effectively preventing them from performing any operations that require authentication.

This behavior is part of the default security settings in the HMI's configuration. The number of allowed incorrect password attempts before a user is locked out can be adjusted in the Runtime settings. By default, this is set to three attempts.

To restore access, an administrator or a user with the appropriate permissions must manually reset the user's status. This involves reassigning the correct user group and ensuring the user has the necessary access rights.

Or simply redownload the entire project, including security settings.

What @Grzegorz Osipiak said.

Just change this setting in your project. Set it to zero or you're going to have the same problem again.
The default setting is ridiculous.

Many thanks for the reply.

The person who's trying to log in already has an Admin account... on the screen it says "USER: Admin" (see attached).



So if admin can't log in, the only way to get around the problem would be to download the program again.

It might be a good idea to increase the number of failed attempts to (say) 500 to prevent this happening again.

Thanks

Thanks @Pete_S ...Set it to zero or a crazy big number?

For Info: HMI is a KTP1200 Basic.

 

[Guynrush]

you can disable the login attemps and avoid similar problems in the future or you can set the number of attemps you want

Thanks for this @Guynrush - my settings were unchanged from the default. They appear as:

I've updated the setting in the software.

The problem now is getting the software installed into the PLC, which is physically on the customer site.

How can I do this? Maybe the only way is to take my laptop (that has TIA installed) to the customer site.

You could use the Pack & Go option

Thanks, that links not working at the moment - looks like SiePortal is down, but I'll try later.

Edit: I've got a Siemens Simatic memory card. One of these:



Can I write the new software to this card by connecting a card reader/writer to my laptop (that has TIA Portal installed)?

Then ask someone to take the card to customer site, and slot it into the PLC? If so, will it "auto-install" the new software when next powered up?

PLC is an S7-1200, by the way.

Yes and no.

Yes, you can put a PLC program on that and send it to them and they can put it in. You can make it a program card, where the project lives on the card and the card stays in the PLC, or you can use a transfer card, where it project gets copied to local load memory.

HOWEVER, this is an HMI problem, not a PLC problem. You need to transfer to the HMI. You can do that on comfort, via USB or SD, not sure about Basic. Pack & Go might be the easiest solution.

 

[Grzegorz Osipiak]

The error is related only to the HMI, so You need to send HMI only. Pack&Go is the option you are looking for. Common SD card will do. You can even send it via email. The other party is required to do some simple preparation, as described here:

Hi @mk42 , good to see you again on here. I'm a bit confused, because the default of "3" screenshot in my last reply was what I see on TIA portal software (admittedly in the 'HMI' branch of the project structure), rather than anything seen on the KTP1200 Basic settings. This would imply the default setting is PLC related - or maybe not.(?)
