hello, I am trying to create a screenshot function for trending graph using SysProcessExecuteCommand in Codesys 3.5.15, using a button. I do not have a PLC, I have an HMI with windows 10 connected to a vibration monitoring device via Ethernet/IP protocol. For this purpose I downloaded Nircmd and put the following command in as input command for SysProcessExecuteCommand function block: 'C:/Users/User/Desktop/nircmd-x64/nircmd.exe savescreenshot screen2.png'. I do not have though any screenshot created...
hello, Just to confirm, can the trace save a long trend for more then 1 month and show it to me in the backward cursor? I have no problem with memory, the HMI is the PLC where codesys 3.5 is installed and it has a wide hard disk (500GB). I believe I can put no limit in the 'Trend Storage'. Marcel, the SQlite files saved by the trend are not readable in DB Browser, just integers. I think they need to be converted to big endian to become float values. How to read these SQlite files? they are very important...
hello Marcel, I have 4 variables in the trend with a sampling of 200ms. the storage size in 'Trend storage' is by default 10 MB. With these configurations can I see with cursor old data values for 1 week backwards ?? Is there any way codesys save/show a long trend ranging from 1 week to 1 month ? Please it is highly important for me to know if possible to make a long trend and saving in Codesys. Otherwise I have to change to a SCADA software to do a long trending. Best Regards, Jad
Hi all, I created a trend record in codesys 3.5 (attached picture). However I do not know precisely how much time can the trend record show me backward. Is it days, weeks or months ? It is highly important to me to know if I can see old recorded values for 1 week or not. The recorded files of the trend record graph are SQlite files, but they are incomprehensible integers when opened in DB browser. Is there a way to make them readable ? I kindly need your support.
Hi, I used the structure VUM_ReturnValues in the library VisuUserManagement.VisuUserManagement_Interfaces, for some variables like 'No error', 'Operation failed', 'Wrong Password'..(attached screenshots), and I entered wrong usernames and passwords but actually I don't see any change in these feedback variables.
Hi all, Thanks a lot. Yeah actually I was able to transfer the files in C:\Users\ directory but not on Desktop, that is after logout from runtime. There are Sqlite files in the trend but I am still working on opening these files. It seems I need to download a certain SQLite browser to be able to read these types of files.
Hi all, I am working on creating a login dialog with username and password in Codesys 3.5 visualization, and it worked (attached photo). I need to know how to get certain feedback variables, like if the login operation is successful or not and if the password put is correct or not. This will help me in creating a condition on VISU_TASK in Task Configuration, because the variables in my application are always shown in real time even before logging in and putting the username and password. I need the...
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...
