I have not seen your code but after time gets updated in PLC is when your HMIDateTime should be reset to 0. I assume you have either control logix or compact logix plc. ![]() If it gets changed – then your HMIDateTime value might be getting changed and changed back before your plc code can run. So change the expression to if ( 1 = 1 ) – see if the event is even firing!Ĭreate a TestTag in the PLC and see if that gets changed in value. ![]() set a delay before the off script can run (why in the server for off it does not know if plc updated ) – 1 or 2 second.ĭoes your event even fire? If not why not?Ĭreate a TestHMITag and tie a graphic to it.Ĭhange the tag in the event to your test tag. ![]() “One script to turn the bit on and another to turn it off again” You can also configure groups of users to better organize them, but we will keep things simple in this document. In this document, we will learn how to set up the users, and secure a display screen. ![]() Clients can send changes to plc via the driver wherever that driver might be located, they do this all the time when the client click start motor or whatever a bit gets triggered. FactoryTalk View Security allows you to secure displays screens or objects with a password. Regardless of what triggers the bit, client or server it should still be activated. Use the Project Settings Runtime tab to log the current user out automatically if the terminal is inactive for a specified period of time.
