Hi, I do not understand why this Function does not work as I intend. It seems to get stuck or jam somehow. The error is that sometimes I am able to send, sometimes dont. I know it has nothing to do with the message build-up. It is somewhere in the sequence-logic.

Can someone please have a look at the pdf and help me out?

Hello.

A TEMP cannot keep its state from one scan to the next. The sequence program relies on the fact that the sequence is kept from one scan to the next.

Your options:

• Use direct memory (DB-tag / M-tag).
  
  
• Move #tempSequence to in-out section.
  
  
• Copy code into an FB; use STAT tag.
