lock a button in operator mode
Hello, I have some doubts with the 800XA and I would like to know if you could help me.
1st I have 4 switches that are activated in operator mode but I want it to be activated only by me in engineer mode. I have gone to the doc and in permissions I have removed the operator but I have taken the permission from all the switches and I only want 4.
2º I would also like to know how to make a push button, what properties do I have to modify so that it is a push button or switch. Thank you

Please see the manuals on System security, and the on-line help in Control Builder for setting permissions on variables.
Security in 800xA is based on "Objects" and the properties of those objects. A variable in the PLC is a property of the PLC Program "Object". Do not try to set permissions on buttons in the Graphics - use the 800xA security model.
Not part of your question, but a common problem when using PG2 buttons is that they look identical to "Page Links". This makes operators press buttons instead of page links - which is a "bad idea".
- Avoid using buttons on PG2 graphics. Buttons should be used on faceplates only.
- If you must use a button, always use the "Direct Entry window" -- DEW -- graphic sub elements to open a pop-up dialog that lets the operator confirm or cancel an action. This prevents operators clicking buttons by mistake.
- See the PG2 graphics manual for instructions on how to use buttons and the DEW graphic sub elements.
