Tag Data Type Modification about l5sharp HOT 2 CLOSED

Hi there,

Yes, you just need to set Value to an instance of a ComplexType.

var tag = new Tag { Name = "Test", Value = new ComplexType("My_AOI_Type_Name") };

This may look weird, but it keeps DataType in sync with the actual type of Value for a given tag (so ultimately you have less work to do). ComplexType is a "generic" data type class you can use to build up a data structure dynamically. Meaning, you can add/remove members to ComplexType in order to load data into Logix upon import.

var aoi = new ComplexType("MyAoi");
aoi.Add(new LogixMember("Member01", new DINT(100)));
aoi.Add(new LogixMember("Member02", new TIMER { PRE = 3000 }));
aoi.Add(new LogixMember("Member03", new ComplexType("SubType")));

Or you can do this more concisely from Tag itself.

var tag = new Tag { Name = "Test", Value = new ComplexType("My_AOI_Type_Name") }; 
tag.Add("Member01", new DINT(100));
tag.Add("Member02", new TIMER { PRE = 3000 });
tag.Add("Member03", new ComplexType("SubType"));

Of course, you could create your AOI type using a C# class and derive from ComplexType, but it is not strictly necessary. It just lets you new up instances of your custom type without have to always add all the members this way.

Hopefully this makes sense. Let me know if you need any further clarification.

5 Stars man! That was a very detailed answer in a very short time.

That's exactly what I'm looking for. Thank you very much!
