[00:00] The Ignition Designer is a live designer, in that it will allow you to interact with live data and it even shows you realtime values. Now by default, in order to protect you from accidentally changing anything in the PLC, the designer is in read only mode. Now you can see there are three little icons up here. And if you go into project in the menu bar, you'll see those same three icons and you can see that one is communications off, one is read only, and one is read write. Now Ignition is going to start in read only. Like I said, in order to protect you from accidentally changing something. But you can come in here and change it to read write if you wanted to go and write down to a tag or to the database or something like that. You can also change in project properties on the designer to start in read write by default if you wanted to. Comm off means that it won't even read the data. And that will help minimize traffic of your network if you need to.
