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...
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
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
Use this project for a first test: https://forge.codesys.com/forge/talk/forge/thread/6ceff9d39e/#49a0/3122 You can connect the outputs, which are now traced to any digital output which is able to toggle quickly enough.
