Hi Phillipp
Unfortunately for you, the string length is fixed. It cannot be lengthened.
Not a useful answer I know, sorry! However I will ask if someone from our Distributor can contact you to discus further programming options for you.
No one from my technical team is in the office today and although I know the answer to your direct question, I do not know what alternatives there maybe available to you, in order to continuing programming!
Thank you and you should hear directly from someone shortly.
greetings Zoe
