Our example is a simple solenoid operated valve. If you have different types of valves, such as an MOV (Motor Operated Valve), or a positioning valve, you may want to create a different UDT for each type. Next, we’ll name the Data type “Valve” and add the members that you will need for each valve.
To create the UDT, right click the “User Defined” folder (in your Controller Organizer window) under “Data Types”. Here is what we might end up with for a tag with a Valve data type after it’s been created: (We’ll create this type in the steps below) The tag would then inherit everything we need for a valve. Then any time we need to use a valve, we can name the valve, and give it the valve data type. Instead of creating each individual tag for every valve, we can create a valve data type. Each valve would have an Open and Closed limit switch, Open and Closed Solenoid, fault bit, fault timer, etc. We might have ten valves in our system, and each valve would have the same data structure. When you create a tag, and give it a timer data type, it’s data structure includes the EN, DN, TT, ACC, and PRE values.Īn example a USER DEFINED data Type would be a valve. The timer data type is already defined by default in a project.

When you create a tag, and give the tag a data type, Studio 5000 knows exactly how to structure that tag.īefore we get into UDT’s, let’s take a look at a pre-defined data type that you already understand. You don’t have to specify each item individually.
