  1. Problems getting WinCC to read a Double

    Dave Long posted a topic in Siemens

    Dear reader, I am writing a C# program using the library  ‘EasyModbus’ that needs to communicate with Siemens WinCC via the connection type ‘Modicon modbus’ I have written a version using the ‘float’ data type in WinCC and that works perfectly. Here my code fragment: Method to convert ‘double’ to bytes in C#: public static byte[] DoubleToModbusFloat(double value) {     byte[] bytes = new byte[4];     float floatValue = (float)value;     int intValue = BitConverter.ToInt32(BitConverter.GetBytes(floatValue), 0);     bytes[0] = (byte)(intValue >> 24);     bytes[1] = (byte)(intValue >> 16);     bytes[2] = (byte)(intValue >> 8);     bytes[3] = (byte)intValue;     return bytes; } Call of the method and loading of the modbus registers in EasyModbus: Bytes = PublicCode.DoubleToModbusFloat(TmpDbl); int n = (int)ModbusStartAddress + ((i - 1) * 2); mb.ModServer.holdingRegisters[n + 1] = (short)((Bytes[0] << 8) + Bytes[1]); mb.ModServer.holdingRegisters[n + 2] = (short)((Bytes[2] << 8) + Bytes[3]); So far so good – this works fine. But I also want to be able to use the ‘Double’ data type in WinCC because I sometimes need more precision than the 7 figures of the ‘float’. I thought it would simply be a case of doubling up the code so I wrote: Method to convert ‘double’ to bytes in C#: public static byte[] DoubleToModbusDouble(double value) {     byte[] bytes = new byte[8];     long intValue = BitConverter.ToInt64(BitConverter.GetBytes(value), 0);     bytes[0] = (byte)((intValue >> 56) & 0xff);     bytes[1] = (byte)((intValue >> 48) & 0xff);     bytes[2] = (byte)((intValue >> 40) & 0xff);     bytes[3] = (byte)((intValue >> 32) & 0xff);     bytes[4] = (byte)((intValue >> 24) & 0xff);     bytes[5] = (byte)((intValue >> 16) & 0xff);     bytes[6] = (byte)((intValue >> 8) & 0xff);     bytes[7] = (byte)(intValue & 0xff);     return bytes; } Call of method and loading of the modbus registers in EasyModbus: Bytes = PublicCode.DoubleToModbusDouble(TmpDbl); int n = (int)ModbusStartAddress + ((i - 1) * 4); mb.ModServer.holdingRegisters[n + 1] = (short)((Bytes[0] << 8) + Bytes[1]); mb.ModServer.holdingRegisters[n + 2] = (short)((Bytes[2] << 8) + Bytes[3]); mb.ModServer.holdingRegisters[n + 3] = (short)((Bytes[4] << 8) + Bytes[5]); mb.ModServer.holdingRegisters[n + 4] = (short)((Bytes[6] << 8) + Bytes[7]); However, this code does not work correctly. I have tried all combinations of byte and word reversal, and whatever I do WinCC either displays nonsensical values or ‘####’ showing that it cannot display the value. I have tried reading as much documentation as I can but it still looks to me as if I am doing the right thing. Also, I have downloaded a number of ‘modbus master’ code examples, and they seem to be able to read the ‘Double’ from my program without any issues. In WinCC I also see that there are two types of double – ‘Double’ and ‘+/- Double’ – I am also unsure as to why this is – there is no ‘+/- Float’ data type, which seems inconsistent to me. I am obviously missing something, but cannot seem to discover what exactly. I hope that someone can point me in the right direction as to what I am doing wrong. Please see attached word file for a picture of the configuration of the connection in WinCC.   Thanks in advance for any help !, Dave Long Double trouble.docx

  3. Hello,           I have installed Simatic S7 5.6 and WinCC Flexible 2008 Runtime SP5 on a Windows 7 computer.  Running Simatic Manager brings up the error message 'Simatic WinCC flexible  -  Older version or not fully installed'            as far as I know, WinCC 2008 is compatible with S7 5.6 and I have installed both fully.  Does anyone have any ideas on how to get this running? Thanks, Rath

  7. WinCC WWTP Example Screenshots

    edecideias posted a topic in Siemens

    Hello everyone. I work with PLC's and SCADA for many years developing industrial applications. Now, for the first time, I have to develop a control system with Siemens PLC's and WinCC for a WWTP. Can some one share WinCC screenshost of simillar applications just to get an idea on what and how put things on screen. Thank's in advance.
  8. Hello all, I worked in controls specializing in Allen Bradley and Fanuc for 3 years after college. I left the technician work to pursue an electrical engineering bachelor when the pandemic hit. I'm pretty burnt out after this most recent year and took a work placement as a controls specialist to get a year off. Although the position was intended to be an intership, based on my prior experience, they are bringing me on with a full time wage with the expectation I wont need any training. It has been 3 years since I've even looked at a PLC. I'm wondering if someone could provide a solid 1-stop resource on the internet to help me get back up to speed that starts off with the basics, but also gets to the more advanced stuff that I would have been exposed to doing controls engineering. I have 2 weeks between my last exam and when I start work to get myself refamiliarized with industry. Thanks.

  10. Open data log in HMI

    Robror posted a topic in Siemens

    Hi there! I have S7-1200 controller connected to a Comfort Panel. The machine has some pressure and temp sensors, as long as many valves and other stuff. I generate a daily datalog with some of those variables but, the thing is, I've been trying to figure out how to show these data in the HMI without using a trend viewer. I don't know if it's possible, but I want to be able to see what valves were open (for example) the day DD/MM/YYYY at HH:MM:SS, using the generated data log, kind of knowing the state of single bits at different past moments. I've been searching the web but I didn't find something exactly like this, don't know if I'm doing it properly so I'd like to know if you have done this or you can throw some light on the topic. Thanks in advance and hope you can help me!

  13. Passwords in Runtime

    RobertyChon posted a topic in Siemens

    Hi I'm looking for a little bit of help. I have a WinCC HMI which will not let me log on with one of the passwords. The general logon and admin both work fine. The Engineer password doesn't work (no display at the top of the screen where the other user names are displayed). There is no warning that the password is in correct or the account locked out (missed in the original programing I think). I have all the project files however I'm using a runtime licence. I would like to log in as admin open the project and clear the password lockout. The issue I have is that I have to use TIA portal and it will not show the project file, is this due to the fact that I have a runtime licence. Is there another way to see if the user name is locked and removed. Like I said I have the admin password which works.   Thanks in advance for any help you can provide. Kind Regards

  16. Deleting Alarm Logs Wincc HMI

    Hi, how can I get rid of those alarms with status I(O) ? They are simply something like duplicates and they re making it hard to read the logs.
  17. Hi, I'm looking for a way to change the button graphic (From "non-pressed button" to "pressed button" which is much lighter) via script.  The main problem is that, the button has to change it's graphic whenever i change a bit in my PLC program, more accurately, I press button in Factory IO, not in HMI, that thing I've already made, so I've set up my button "is pressed" graphic. I've got my tags prepared correctly, and I'm trying to reach the property of the button with this script:   Do  If SmartTags("Variable_1") Is True Then     HmiRuntime.Screens("Screen_1").ScreenItems("Template_Button_2")  End If Loop Is it even proper way to do stuff like that? I THINK it'll work like, if Variable_1 (Bool %Q0.0 for e.g. in PLC program) is 1 Then ->  And when I'm at ScreenItems, i don't know which property should I choose next in order to change button graphic.   Hope you can help :)
  18. Regards! My problem is the following. I have a client that has 7 different machines with touch panels SIEMENS TP277. A touch panel for each machine. The machines are different and therefore the projects that have to be loaded from WINCC Flexible to each panel are different. That is, 7 different projects. My client wants to have a single spare screen, not 7. Is there any way that he has a single spare physical panel and without needing WINCC Flexible can he load the same one of the 7 projects? Can not you record inside the panel and then load 1 of the 7 you need? Or via USB memory? ZhankS!   zHANKS!

  20. Optimized Blocks

    Doeyjohnny posted a topic in Siemens

    Hello everyone, Are there any alternatives to WinCC at the moment that can handle using optimized blocks. In most other SCADA software, while importing tags, the option to optimize blocks should not be selected as they cannot import in this format. Ignition by Inductive Automation has a driver that can be purchased to solve this problem. I wanted to know if there are some other solutions to this issue.  Thanks!
