[jira] [Commented] (PLC4X-337) S7 CAN NOT WIRTE STRING EVEN THE STRING SIZE IS LESS THEN 240

    [ https://issues.apache.org/jira/browse/PLC4X-337?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17498403#comment-17498403 ] 

Christofer Dutz commented on PLC4X-337:
---------------------------------------

Try omitting the array notation at the end.

But admittedly strings are the most complex datatype we have and it's not that we'll tested as it seems to be seldomly used. 

I was thinking of creating a crowd funding campaign for fixing the datatypes in s7. Is your company willing to support such a campaign? Otherwise I am sure others will be willing to jump in and tackle that.
