This feature allowed me to use a single faceplate or screen to display or modify data from multiple objects by simply changing a single tag. I was so excited, I even wrote a blog post about it then!

And I'm in luck! While I've gone into some detail in my previous blogand all of the same information is relevant, here's a really quick demo to set up multiplexing of an array of UDTs from your HMI.
First, I've created a really simple project with a S FW v4. Note that as of right now, this tag is linked directly to a fixed item within your array - in my case, " dbDemo. VFD[1 ]. To do this, select the "Address" dropdown under the properties of the tag. Notice that in your tag table the address has changed to indicate the position in the array is defined by our" Index " tag.
And that's it! Now, we can change " Index ," either through a script or by a control on the HMI, and our multiplexed tag will look at a different item in our array. To take this a step further in your quest for object oriented programming, take another look at my previous blog.
It will take you through linking your multiplexed tag to faceplates and popups - which is where this feature will really help you develop better, more powerful, HMIs. One more helpful hint - you will find that your index on the HMI will be zero based, regardless of the way you define your array on the PLC.
For example, if I defined my array on the PLC to be [ Name required Name Is Required. Comment Is Required. Notify me of followup comments via e-mail. Blog Categories. It's back! Miguel Tavares.

The Library is Open Source and will allow for users to contribute content to help enhance the overall availability of functionality to the greater Siemens User Community. Special changes have been made to accommodate S and S processors, however these processors are no longer being actively developed for final version is 2. However, the project is activity supported by both the community and DMC — updates will continue to be released on a regular basis.
The Siemens Open Library contains many components to assist with development. The library contains the following items:. Here is a short list of the supported and fully documented blocks contained in the library. Please consult the documentation for a full list and descriptions. Library objects may not be added immediately, but will be added as additional versions of the library are released.
Tag prefix will be assigned to the parent Screen Window that loads screen.

First, allow me to describe the situation that led to the need for a completely dynamic faceplate. A client gave DMC a project that needed an HMI interface that allowed operators to add, remove and edit steps in a user-defined sequence.
Each step in the sequence had a type and several Boolean, integer, and floating-point values that the operator alters to change setpoints for that step. Because only some of the settings were used in each step type, and there were a lot of settings, we decided that it would be simplest if the HMI displayed only the parameters relevant to the selected step type.
At a high level, think of the dynamic faceplate as a junction box that connects the HMI objects to different PLC tags, depending on the step type.
The faceplate contains 21 objects, seven switches, seven drop-down menus, and seven IO fields, that are all linked to tags internal to the faceplate. The faceplate also has 15 interface connections, four Boolean, three Integer and eight Real, that can connect to PLC tags.
When the faceplate receives a new mode, it pulls the values from the PLC tags and places those values in the corresponding HMI objects. The step type is a 32bit integer it uses the lower 28 bits that the faceplate interprets as seven, four bit, nibs.
Each nib contains a number from that corresponds to either a blank space or one of the 15 interface connections. The abbreviated code snippet below controls the visibility of the screen objects and passes the data from the screen object to the conection tag. The first script, shown above, runs when the current step type changes and the second script runs when any of the HMI objects values' change.
As mentioned, the first Visual Basic script runs when the step types' tag changes. It masks and shifts each nib to the left giving seven location modes each ranging from 0 to Because each of the seven locations on the HMI can be linked to any one of 15 different tags or left blank, there are a lot of possible modes,in fact.
Finding the desired modes and copying those into a project is not a trivial task. To create a list of step types you have to fill in each row with the tags you want to appear on the HMI, and then copy the list of types and names into an HMI text list.
This dynamic faceplate demonstrates how using Visual Basic scripts within faceplates can further increase faceplates versatility and capability, reducing project-specific complexity and needed PLC logic. With this tutorial, you should have all the ideas and information you need to make your own dynamically linked faceplate for specific or general applications speeding up complex HMI development.

This process is time-consuming and incomplete since it misses much if the block's metadata and some blocks can't automatically convert into STL. Before we can re-import these into V14 SP1, we have to change a few parameters. Importing a screen with a faceplate that is not already in the project library will crash Openness and TIA Portal without any error message. However, it's still possible to import these screens. To import screens with faceplates, first import, or recreate, a matching project library and make sure that the library file structure and versioning exactly match the structure and versioning of the original library.
Then import the screens one at a time saving in between each import in case any library differences persist. Similarly, importing program blocks with arrays of data blocks will throw an error due to differences in formatting and syntax in the interaction of XML and TIA Portal.
Working around this error is more difficult and time-consuming. We found the quickest solution was to replace the arrayed data block references in the.
This method does require a solid understanding of both.

S PLC can work fully "symbolically" and that means that we do not have to use any numbers anymore, because the name is leading.WinCC: How to Create Faceplate
We do not get address offsets and all the locations of the data can be just fully name-oriented. Very nice, because the name is the name, so if I change something in my block structure, the name will be recognized anyway.
Thus if my "Motor1" data block has a number 10 DB10 - yes, the blocks still get the numbers and "start" bit in this block is my start bit, then I can just acces the data, this particular bit, by typing "Motor1. And we cannot use the data block name as a multiplex value!
All in the Siemens world goes in the way of name-oriented programming, but is stops abruptly on this point, overlapping of the PLC and visualization HMI world. Either I have to create the way to read the name and convert it into the number or search for another creative way to combine this.
I want to be independent from the DB numbers and addresses. Is there any idea how to elegantly solve this obstacle? I would like to think and program in names! In symbols, in names only! And then? What can I achieve by this? Because when you create your FB "motor" or "valve", you create or do it a struct with all the tags you need You link your FB with your struct Thank you for your input.
Last two days I have been testing different options with Faceplates. Since I had almost no any experience with faceplates and use of them seemed a bit exotic to me, I wanted inspired by you :- to once learn all about them and search out the possibility and limits. Unfortunately this is not what I need. It cannot be used to replace the multiplexing in the meaning of "multiplexing" we want to use.Pop-ups essentially function as global faceplates.
This pop-up can be called from any screen and will be placed at the configured location on the screen. The main difference between faceplates and pop-ups is that pop-ups do not have their own interface or properties.

This means that you cannot pass information to the pop-up when it is called, and instead need to rely on multiplexed tags and scripting in order to achieve dynamic functionality.
Below is a picture of the pop-up screen editing window and an example of a VFD motor control pop-up. Notice that it is very similar to the regular screen editing interface.
The only difference is that the size of the pop-up can be configured. This is easily done via the Properties menu. It is important to note that pop-ups are NOT modal — any visible items on the screen from which it was called can still be interacted with, though the pop-up will remain on the screen regardless. Slide-in screen configuration can also be found in the Screen Management section. They function similar to pop-up screens, but have a few distinct differences:.
Any normal control can be placed on a slide-in screen. In the above example, a static text is shown.
If you are still using V13 without the service pack, I highly recommend upgrading. Feel free to contact DMC with any questions or to get started on your next project.

Slide-in Screens Slide-in screen configuration can also be found in the Screen Management section. They function similar to pop-up screens, but have a few distinct differences: There are only 4 slide-in screens, one from each direction.
Each of them are global, so you cannot create as many as you want, unlike pop-ups. Slide-in screens do not need to be accessed by system function calls although there is a system function if you prefer. Instead, if they are enabled, they may be accessed by pressing near the edge of the screen for which they are configured, and then clicking the handle. The visibility and functionality of the handle can be modified in the slide-in properties. Jeff McCormick. Monday, November 13, PM.

Before we get started, let me say that if you're not already taking advantage of PLC data types and Global DBs to build rich data structures in your project, you're missing out.
And let's face it, the less time we all spend on repeating tasks and minutiae, the more time we can spend actually programming. As an exercise, let's pretend we have a project with a large number of simple valves. So, what is in our 'valve' data type? For this simple example, let's create the following PLC data type, udtValve :.
We've broken our data type into three structures: configuration, status, and control. The configuration group of parameters defines the valve's physical behavior and its unique name. I find breaking things up like this makes it much easier to find the right tag you're looking for when programming.
For our valve Function Block, fbValvelet's say we have something like this:. Now that we've developed a re-usable function block for our valves, let's create a DB to contain all of our valve data.
I'm going to create a Global DB and name it dbValves. In it, I am going to create an array of udtValve. Within this data block, I can set configuration values, including valve names, for each of the valves I am going to use.
Let's imagine we'll be using 10 valves. As you can see below, I've entered configuration values in each valve's data structure. The final step on our PLC is to add our newly written code. Now, let's move to the HMI. Let's also imagine we want to allow a user to click on a valve and open a pop-up so that they can get more information as well as control it manually. I'm going to grab a simple valve from the toolbox under "Elements - Symbol Library" and add an indicator for the valve name.
Additionally, I would like the valve's name to change to Red and flash when the valve is faulted. I could start adding in my animations now, but I don't want to have to redo that process for each valve. Instead, I'm going to create a faceplate so I can write the logic once and reuse it several times. To do this, select both the valve symbol and the valve name indicator, right-click, choose "Create Faceplate", and name it 'ValveIndicator'.
However, this would require linking each of these properties back to the appropriate tag inside of my data structure. With a lot of valves, this could take a lot of work.
Now, back to our Faceplate. Let's add a new property of type udtValve. Now when we use this Faceplate, we will only need to link a single tag: all of the individual animations and properties will be internally linked, within the Faceplate, to the appropriate tag within our UDT.
Below is my Faceplate and the animation for the valve color. Notice in the Properties window that there is only a single property of type udtValve. When you're finished editing your Faceplate, release the version and let's go back to editing our HMI screen. Select the new Faceplate object and view the Interface tab. Link it back to dbValves. Valve by navigating to "Program Blocks - dbValves". That's it! Now we can add more instances of our Faceplate to the screen and simply link a new valve instance to each - nothing to it!
So, getting back to our original goal - we've succeeded in creating a simple Faceplate that can be linked directly to a single tag UDT.
