How it works
Passing a valve position can be done in several ways. Obviously, it’s up to the end-user to choose which way(s) fits best with their business. Some options we’ve come up with so far, are:
After scanning a Tag, an “Open” and “Close” button appear with either a photo of the newly scanned valve, or an icon.
A slider appears so that the (approximate) position (between 0 – 100%) can be communicated.
There are two Tags mounted near the valve (e.g. a green for Open and a Red for Close), so the operator does not need to do any additional work on the ATEX Device.
An overview of several valves appears. By clicking on one of the valves, the position of this valve can be communicated.
More options are possible and conceivable.
The control room has a dynamic overview showing the current valve positions. There are several possibilities for the visualization of the valve positions. Below is an example of a tank terminal, in which the open valves are colored green. The lines in which these open valves are located have a thicker line-weight to indicate that flow is possible. The closed valves in this example are white and the lines are thin.
In our dynamic valve position overview software you can intuitively browse through all the relevant P&ID’s. Also, the Valve Identifiers (e.g. the P&ID Tag names) can be easily shown or hidden in the overviews.
For each valve, a history list is available when it has been scanned and what the position was at that time.
If the Field App is being used for trainings, or for certain pre-defined line-ups, which involve a list of valves that need to be checked, the dynamic overview software can display whether a valve has been scanned yet and whether the valve is in the correct position (v) or not (x).
