Hi

We don't usually have a special screen. Just I have showed PDIC , PIC and HIC with a high selector on vent valve(or recycle valve).
Also in case you have surge detection, it can be shown as message which can be shown when it is triggered.

We have built a graph to replicate one shown on a compressor UCP - we handled it using a static graph background (actually an image of an Excel chart), and then overlaying the 'live' point, with the position of the point changing depending on current conditions. It might take a bit of work to get the x and y co-ordinates lined up correctly, but apart from that it isn't all that difficult.

Is that similar to what you are looking to do?

Hello david,
correct, something like this is what I need, what I don't know is how to start locating the points of the variables in that reference image and that they move according to the variables communicated from the PLC. Do I need any new activeX?

In reply to DCS_Project:

I'm assuming that you already have values in the correct units for the X / Y - probably easiest to calculate them in logic if you don't already have them on the link from the PLC.

Just to check - are you using Operate or Live? This was using Operate, so once the image was in place it was simply a case of using the Vertical / Horizontal animation experts to get the necessary X/Y values - if you move the marker to the correct location then you can pull the variable using the expert (at least you could in 12.3 - not sure if it is the same in 14.3 and not able to check at the moment).

If you are using Live then I'm afraid I haven't used that enough to give an answer.

In reply to David Scott:

This is what we have, again, using Operate, not Live.

In reply to MPHymel:

Yes, something like that is what I need, is it possible you can send me that configuration in Operate?

We use Triconex, and our application was created by the Triconex Turbo Machinery group in Webster, TX.

The various OP_Pnt X & Y and (our operating point)FLOW and DeltaP references below are read from the Triconex system.

The operating point position X and Y expressions:
X: G_HC_RGC_SURGE_MAP.Group378.Rect7.Width / 100 * DVSYS.HC_RGC_SURGE/OP_PNT_X.F_CV + G_HC_RGC_SURGE_MAP.Group378.Rect7.HorizontalPosition - G_HC_RGC_SURGE_MAP.Group378.Group379.Width / 2
Y: ( G_HC_RGC_SURGE_MAP.Group378.Rect7.VerticalPosition ) + ( G_HC_RGC_SURGE_MAP.Group378.Rect7.Height * ( ( 1.38 - DVSYS.HC_RGC_SURGE/OP_PNT_Y.F_CV ) / 0.35 ) ) - ( G_HC_RGC_SURGE_MAP.Group378.Group379.Height * 1.5 )

Surge Line segments are as many as necessary to represent the surge curve set up in your surge control system.

please i need screen anf module deltav please.
