Good morning to all, 

I would like to share an FB that I wrote that store several strings in a user definable byte array buffer.

This buffer could also used to feed the attachment input of TM_MAIL FB. This could be useful to send a log, since S7-1200 cant send datalog files itself.

Please test it and if you see some bugs, correct and improve it.. then share to someone could be searching something like this.

Have a good time.

Luca
