  1. Change Value of External Tags in WinCC 7.4

    Hi, Im trying to change the value of my external tag DB31, DW54. My plan is for the user to input the values in the I/O field and click a button to change the value of the external tag. My problem is I can only do it through left click event direct connection on the button but it can only change the value once. How do I do this dynamically in runtime?   Thanks,
  2. Hi all, I had 2 sets of Wincc HMI, 1 is v5 and another is v7.2. In this case, is it possible to configure "alarm broadcast" to both HMI PC between v5 and v7.2 ? Alarm broadcast I meant was the when alarm trigger from v7.2 it will appear at v5 HMI as well. and able to acknowledge too. If possible, any advice without additional software and hardware?

  4. How to use the template in a project or TIA Portal WinCC Flexible to show the same icons on all screens of our project.

  5. I am working on a system with a siemens plc and HMI using TIA Portal V13 and WinCC. I wanted to remove to buttons from the HMI so the operator no longer has access to them. I removed them in the project (saved them on a temporary screen). When I uploaded the changes to the HMI, the buttons still exist. I also tried the simulator and I had the same results. Do I need to manually un-register the buttons somewhere? Also, I made a new screen and changed one of the screen change buttons to direct toward it. When testing it, a blank screen showed up instead of the screen that I directed it to. I have done a lot of plc/hmi programming in the past, but I have never experienced symptoms as such.  I am new to the Siemens world.  I have traditionally used AB products.   Are there a lot of nuances with WinCC that I am unaware of?

  10. PLC Programmer Job

    Hi there! I`m a PLC programmer from Romania and i work in automotive industry. I know to program in Step 7 and in Codesys. I`ve been working with S7-300 from Siemens and Wago 750-881. I am also designing the electrical drawing for my project in a software called WSCAD. I am trying to leave abroad because i have a low salary here and i am wasting my knowledge. Can anyone give me an advice or help me with finding a normal paying job in plc programming? Thank you very much in advance and have a really nice day!
  11. WinCC Runtime on Server

    Hi, I'm trying to integrated a couple of machines with S7 300 series CPU's onto an existing industrial VLAN, The two machines currently get their recipe information and send their archive information to a PC running a Win CC runtime package on a separate VLAN. I've changed the IP addresses and can get the Runtime package to work from my PC but not the server that I have been provided with. It's as though the server is too slow, it takes about 3 minutes to establish a connection with the PLC and the monitoring word the PLC sends to the PC to ensure comms is not returned, however when I run the same Runtime file on my PC on the same VLAN it works fine also the ping TTL is only about 3ms. Does anyone have any ideas what could be wrong ? It may be worth saying that this server is a just a partition of a bigger server running a VMware package.
  12. Hi friends, I have about 60 on-off valves each with about 6 signals in my current project. Recently, I have learnt how to make a face-plate for this and connect the face-plate's property interfaces with tags needed for each valve. Now I wish to make a single pop-up screen to control these valves. When I click the face-plate of a given valve, its tags must be assigned to the pop-up screen that will have switches/lights for its control & status. Thanks for looking in and I shall appreciate all advice for implementing this.
  13. Hi friends, I am a little new to WinCC. I am using a WinCC RT Advanced license within TIA portal v13.1 I need a little help in my current project as described below. I am attempting to create a faceplate of a solenoid valve,, The "Valve" is a user-defined data-type with the following 4 elements 1. Cmd - or command. - Bool 2. Cls_Fb - or Closed -Feedback -Bool. 3. Aut - or Automatic Mode -Bool 4. FTC - Fails to close -Bool. I tried the following procedure as described in TIA portal help.. Method -1 1. I created a User-defined data type called Valve comprising of the above 4 bool elements. 2. In the graphics I made a image of solenod valve with one rectangle (solenoid) and one polygon for valve body. 3. Under the Faceplate Properties (See figure attached) I inserted a property ang gave it the data-type Valve as above. However, when I drag a property from the 'Contained objects list' to the interface side, it is not getting substituted. such as the Rectangle_1 's background color I try to associate with the interface property Valve.Cmd. It does not get assigned when dragged. Since this does not work I tried another approach, Method -2 I attempted to declare a variable tag of UDT type 'valve' in the faceplate's tab Tags. I found that it is not possible to declare a local variable of User-defined types here. Please guide me how to proceed. Thanks for looking in and best wishes for your success. Regards, Raj S. Iyer
  14. Dear all, I have implemented PID temperature control for mini heating tank system using Siemens S7-313-c2-DP PLC. Now, I want to plot the values of the "process value (temperature) " and "Setpoint" as a function of time in wincc flexible runtime. I am using wincc flexible 2008 advance SP3. However, the problem is that I have tried plotting the value of "process value" as a function of time using trendview, But the change in the value is not smooth i.e. it is in step manner. Besides, the value of temperature progresses towards the left side of the graph, but I want it in the right side. And also I would like to plot two values against time in one graph in smooth transition so that I can make the comparison and I want the plotting only on the right side of graph. So, how to do all these things? Since, I am a newbie to WinCC, I would appreciate your help. Thank you. Regards, Ankur Gajjar
  15. Daily logging of flow in WinCC

    Hello, I am working on a Siemens S7-300 PLC with a WinCC HMI and I am looking to perform logging of certain values every 12 or 24 hours. Basically I have a Flow meter that constantly has flow through it. Right now I have the PLC set up to record the current value of the flow, as well as a totalizer to indicate how much flow has gone through the valve. (until an operator chooses to reset it) I need to create some sort of logic or utilize something in WinCC to calculate the flow through the valve only for that day. After that day, the value will be either deleted or replaced with a new value the next day... If anyone has any tips or advice it would be greatly appreciated. Thank you,
