Multistate Indicators


Multistate indicators look at a value in the processor, and reflect it's state based on the value of the tag it's referencing.


In this example, we will create a multistate indicator that looks at O:1.1/0. When this bit is high, we will display the text “Bit On”. When this bit is reset, let's display the text “Bit Off”.


  1. First get the Multistate indicator object. (Objects | Indicators | Multistate)




  1. Next, draw the object on your screen. In this example, we'll just put the bit on the main screen.




  1. Double click the multistate indicator object to access it's configuration screen.



  1. On the STATES tab, delete all states except for 0, 1, and error as shown:





  1. Configure state 0 to read “Bit Off” and State 1 to read “Bit On”




  1. On the Properties tab, configure this indicator to look at a single bit. We have to create a tag to relate this indicator to O:1.1/0, so click the button “Edit Tag”.




  1. Name your tag as shown, select the node you are communicating with, and set the address as O:1.1/7





  1. Press OK. When finished your screen will appear as shown:




  1. To see what the object will look like in various states, you can access the pull down tab in the tool bar to change the state of your object.
