Different symptoms on FS4 FW1.81.01

Dear Everybody!

I recognize a different symptoms on FS4 FW1.81.01.

In my case at long term operation PLC handling and front panel are freeze, but the web display always works fine and show the real data of moment of freeze (IO ….).

The symptoms are same in case of 24V (ext pws) and 230V LOGO!8.

Anybody recognize this problem too?

Can fw upgrade solve it?

Thanks for any advise.

Split from Product information on LOGO! 8 FS:04 and FS:05 to errors.

Dear IOX!

Sorry, but for me the situation

"The display (onboard display, TDE and web server) is no longer refreshed."

and the

"PLC handling and front panel are freeze, but the web display always works"

is different.

I accept any usefull answer (information) including "nobody recognize this symptoms before".

Because from some viewpoint LOGOs are in critical position, for update I need to get more permission, and after I must do short and long term post monitoring. This is why I think twice before I try the frirmware upgrade.

Other side to testing in a lab need 2 month time.

Looks like I have no other chance than try fw upgrade, and we will se whats happen.
