Need some help for two simple things

Hi, I inherited a Zenon project and have to add a new PLC and some new functionality to it. System is Zenon Supervizor Version 7.60 SP0 Build39532, PLC is Festo CPX-CEC-C1-V3 (Codesys 3), so I'm using the Codesys driver (3S v3 driver for PLC handler). What I can't figure out is the following: 1. How to set a PLC variable by clicking a button? Say I have the variable PLC1.word1 I want to have several buttons which set this variable to different hardcoded values - for example when Button1 is click, PLC1.word1 becomes 105, when Button2 is clicked PLC1.word1 becomes 1001 etc. The user should not see the variable value, nor any dialogs. Can't find any way to do that. In the buttons Properties, the Variable field is grey(Inactive). 2. How to change the color of a screen object, e.g. a circle, depending on the value of a specific bit from an integer variable? For example if bit#5 of PLC1.word1 is False - the circle should be green. If bit#5 of PLC1.word1 is True - the circle should be red. Thanks for any suggestions. Best regards, Peter
