Freelance V9.2 function block M_BIN message type configuration
Voted best answer
The message text is not limited to the values of the dropdown list. You can type in everything (limited to 8 characters).
The message text is stored in 800xA as text into the "General Properties:Mt" property.
The 34 is fix on every M_BIN, set by uploder. I think it will point to something like "Category=Discrete, Event Type=Condition Event". There must be a list of all EventType values somewhere in 800xA, but I can't find it now.
