Post by andrea199403 on Assigning Modbus addresses to a structure in a dynamic way ^{CODESYS Forge talk (Post)}
Hello everyone, I am new to this forum and I am also new to Codesys programming. My problem is this: I have a STRUCT of 64 bool and 30 real, this STRUCT is assigned in the programme 9 times. Now I need to communicate with an HMI via Modbus and I have defined the slave device and created the holding registers for communication. I would like to declare the first call of the STRUCT on the Modbus registers %QX2000.0 to %QX2007.7 for the booleans and on the registers %QW1004 to %QW1034 for the real registers. That said, I would like to change an index and set an offset of 100 bytes for the calls of the other 8 assignments, so that the result is: %QX2100.0 to %QX2107.7 for the booleans and on the %QW1104 to %QW1134 registers for the Real registers, etc. Is there a way to declare this? Thank you very much.

sorry I missed to say how to do this just update the runtime. (extract latest debian package out of the CODESYS package) but 8n this case an update all to the latest version including CODESYS is probably the easiest option now.

It looks like one can use the OutputData and InputData members of ETCSlaveStack: https://content.helpme-codesys.com/en/libs/EtherCATStack/4.2.0.0/EtherCATStack/ETCSlaveStack.html

Is there perhaps a place where I can see examples of programming with different instructions? This would be a great help. Maybe there are some places where ready-made programs are posted that can be downloaded and tested? /Klaus

I have now and it works. I had the idea that it had something to do with codesyscontrol.cfg, but where can I find a description of all the things you can set in codesyscontrol.cfg and its syntax?

After carefully studying the documentation, I have a question: is a second hardware-independent time source required for the correct operation of the VirtualSafety system?

Thank you for your response. Is there documentation for the commands? I spent a lot of time trying to figure this out. I have a potato computer at home, so I'll have to test this later.

Post by timvh on Access Violation sherd memory ^{CODESYS Forge talk (Post)}
Maybe it is better to use Interfaces to access the objects instead of pointers. But besides that, is "read_obj_ptr" a method? If yes, you need to call it, so add brackets behind the method call: read_obj_ptr();

Maybe check: - The library manager, are you maybe missing some libraries - Tools - CODESYS installer: update the CODESYS Visualization and Visualization support - Project - Project environment: maybe you need to update the visualization profile

I experienced the same problem: using __VARINFO is working only in PRG context, while it crashes if used inside Function Blocks. I would really appreciate if they would fix this issue

Hi kenth1973, it is not a matter of who created the function block. It is just that we don't have, and don't provide, documentation about internal implementation details... Hope you can understand that, Georg

Hello Tim, I am using CODESYS Visu V4.8.1.0. It works when I turn off the "Support client animation and overlay of native elements". But if I do that, dialog box moving and other options are also disabled so it is a bit problematic. Thank you for helping.

No that is not possible for function blocks, although it is possible to that with methods and functions as you see in your second pic.
