There are a number of bluetooth options available in various development boards (such as the Arduino), I remember seeing one on Kickstarter recently that allowed basic IO to be controlled via Bluetooth. Then you can write a custom App for your android device and control the board remotely within reason. Alternatively, as AndrewG mentioned the regular Arduino board does come with a wifi / Ethernet shield that could be used in combination with a website/service to control inputs via the web. A simple website accessed via a browser on the smartphone could chat with the board then the PLC. -
Hi all, I'm trying to improve the flow of an HMI (Panel View 1000) such that when a user taps a button and they do not have permission to that operation (change a value, navigate to a screen) the HMI would automatically take them to the login screen. My thought would be to create a tag in the background to establish who has access / permission that I can run a check against. I can setup another tag with a message that would change to tell the operator why the login screen appeared, something along the lines of "You must be logged in at a Supervisor level to complete this action". The part I can't seem to figure out is the actual button logic. Is there a way to create a macro that would handle something like navigation. The documentation I found show the macros being limited to simple options. What I was hoping for was some sort of button that ran a Macro along the following: User selects button to navigate to Maintenance Screen If userPermission = 1 Then goTo MaintenanceScreen1 Else goTo LoginScreen This method would require I code each button that has a restricted permission but I think the UI / operator interaction will be better, clearer for someone not familiar with the process. I'm open to other suggestions to accomplish this as well! Thanks in advance! -
Hi all, So this is more of a theory / how would you attack this problem, question: I'm creating my first HMI and while playing around in FactoryTalk View Studio I noticed I can add objects to a screen. I can add a browser and with some work I can get it to display an HMTL file directly in the screen. So the browser in this case is opening a file stored locally, not something served up from the internet. Which opens up the question, could I write most of my HMI in HTML and Javascript? As a previous developer having the ability to control more of the UI would be amazing and perhaps easier to use/maintain. The only pitfall that I haven't been able to figure out is how to get real time values from the PLC. I'd welcome anyone's input on the idea in general or if someone knows a good method for getting/setting values from the PLC. Thanks!
