Here is a basic rundown of how switches/indicators/etc work for easybuilder:
You have "objects". These objects do things. Like a bit lamp, which is on, off, blinking, etc based on the status of a bit. There is a word lamp, that compares the value in a word to a set of values, and acts accordingly. There are all kinds of objects in easybuilder. Each object does something specific, and has a set of parameters that tells it how to act.
Of those parameters, for instance, you have an address, to tell the object where to look and also a parameter to tell easybuilder to use either a picture or a graphic. You can make your own, or there are additional ones on the easybuilder site.
There is a manual, but we would need to know what HMI you are using. I suggest going to the site for your HMI and looking through the documentation for your specific product.
Addressing is a bit tricky on easybuilder. You would need to let us know what type of connection you are using, and give us specifics about your hardware in the system to really get much help. You may also want to search through some of my past threads on the forum, as I just learned how to use easybuilder over the summer.
