hi 

how can i remove Event ID 16# 2522(Area length error when reading) ?

i loaded 10 SFB 4(TON) in FB102. this event happened if 11th SFB4 loaded.

Hello Poryabaghal,

this error is not about the SFB, it comes e.g. when you use an indexed tag (array) with an index that is out off range.

To get further help, you should post your code.

Regards,

Frink

thanks so much for your help.

i solved it by remove DB and creating new DB.
