This drop-down menu allows you to secure your exchanges by signing and encrypting the data you send and receive. NOTE: Anonymous login is disabled when User Rights are activated, regardless of the state of this parameter. Select this checkbox to require that clients provide a valid user name and password to connect to the OPC UA server. If(currentMillis - previousMillis > 2000) // Scan This peace of code only every 2 secondsĪnalogue = Sensors.This checkbox is used to enable or disable the OPC UA Server on the controller.īy default, this checkbox is cleared, meaning that OPC UA clients can connect to the server anonymously.

It seems like every time the onewire device is accessed the OPC quality changes. Just to recap: when the piece of code " if(currentMillis - previousMillis > 2000)" executes every 2 seconds the OPC tag quality changes from good to bad and back to good. So you could use the support forum for news, updates and bug fixes
I am creating a new site for the Arduino OPC Server at: Could you send me your sketch or al least the line where you create the OPC Item? AddItem(… Yes, i can imagine where is the bug in the Arduino OPC Server. VisBee: thanks for your Feedback in this point, I will forward it to the “special forces team” Hi Paul, thx for the infos! Ich will check the “Error” at our page…
There are other pages that do the same, you will need to check to find out which pages do not work. If go to this page and then select the English flag at the top of the page for English then all I get is a blank page. How wonderful it would be if we could have our operating system of choice and be able to use some of these programs.Ĭhris, a problem with your ‘visbee’ web site. I feel irked by having to keep software like this for work I do in Industrial Automation. Just like ‘Citect SCADA’ and the Allen Bradley RSLogix range of software products, they all only operate on windows, and this is the only reason I keep a windows image available in VirtualBox environment. What a shame VisBee only seems to operate on microsoft windows, I hope you are also looking to have it operate on other OS’s.
