    Thank you for your response! Unfortunately this mouse click is - as all the other input configurations also - only an event. If the method or function runs more then one cycle, this wont work. Even if that would be bad while its hidden code. Or am i wrong? An other option would be, that the TextVariable would be linked to a cyclic called variable, e.g. Prg_Visu. There the variable could call a method or function until those is finished. But that will completely separate the functionality from the...

    By investigating PLC Log I have discovered that there is no requests to PLC in above case, because the lines about client creation are absent. So it is not PLC who suddenly closes connection. It seems weird troubles with local WiFi on iPad. However, the link to the same Visu with external global fixed IP (not LAN IP) is working ok.

    Hi, Ingo, thank you for your quick help. I would like to try the PWM system like the thread/3122 on my Raspberry pi. But I can't understand the way how to apply the system to pi. I'm a very beginner, so will you help me more? Is this an example for the CODESYS control for Linux?

    Hi all, I have a trace record graph in which I display a vibration sensor values. I have a problem with accessing the recorded data in the connected device (VSE151 vibration monitoring device). In Device--->Files you can find the directory of the trend recorded data (/PlcLogic/Trend) in the internal memory of the device VSE151, where the recorded data file is in xml format (Application.TrendRecording.xml). Please see attached pics. The problem is that I cannot copy the file from the internal memory...

    Let me check, seems we mis a posibility to force the lib to use either TLS 1.1 or 1.2

    Check the modem documentaion... To Figuren Out which device on the Pi /dev/tty.... Ist used

  • victorherma victorherma posted a comment on discussion Runtime

    Hi Edwin. Yes, the modem supports AT commands, but where do I write them? In a POU? How do I indicate the COM port of the UART? When I use the example included in the SMS Service SL library, modified for the raspberry, the TimeOut runs out on the first initialization of the modem and it goes into error. I suspect it has to do with the ModemFb.itfConnectionType

    A pity! Sounds like the driver has a problem then. Then it doesn't like the usage of the driver from different tasks. I'll file a bug for that. Sorry, that it didn't work that easily! Cheers, Ingo

  • scan scan posted a comment on discussion Forge

    Thanks Ingo! I uploaded your example project to my raspberry, but the problem still exists. The traces are correct, but on the GPIO pins it's not working properly. I am now trying to solve the problem by programming the PWM signal in a separate phyton program. It should be possible to access the variables of the plc program. BR Andreas
