    Thank you, with your project and tips I got the desired result.

    You can use the "Read" functionality. When you call this (after you opened the file succesfully), the result is written in the buffer you have assigned when you call the Read function. Then it reads the amount of the size of the buffer, of if the file is smaller than the buffer, the whole file. From this buffer, you can use other functions to find the string you are looking for. So in the example at the top, the variable "Data" will contain the contents you read from the file.

    Hi, Thanks for the input. I tried working with CAA file and the examples but i did not managed to come up with a solution. I first opened a directory and then a opened file but can't copy a value to a string, out of it. Could you may be tell me what function should I use exactly use or an example for the problem? Thanks

    Greetings. I have a Wago 750-652 (RS232-485 module) connected in RS-485 to a vacuum pump using a custom protocol. The communication between the PLC and the pump is working, and I can send and receive messages from the pump with the i/o check tool of Wago. I want to make a program which is able to control the pump and retrieve some information of the pump such as temperature, speed, ... Nevertheless, I'm not sure about the implementation of this kind of program. Indeed, I have to send a lot of messages...

    timvh, greats thanks for your info and project. One important question - should I see my "Login Visualization" instead of "DefaultLogin" from your first screenshot, right?

  • timvh timvh posted a comment on discussion Visualization πŸ‡¬πŸ‡§

    Link works fine (now)

  • timvh timvh modified a comment on discussion Visualization πŸ‡¬πŸ‡§

    You only get to see this, if the general access to the web visu should or is protected. So then normally you will see the DefaultLogin. In your case add the following to the CODESYSControl.cfg and restart your PLC because this will add this standard protection: [CmpWebServerHandlerV3] AllowFileTransferServices=1 Maybe good to know is that you can quite easily create your own login pages, but some steps have to be followed: 1) Add user management functionality (based on runtime access as you showed...
