An interesting remark for CODESYS Support. I found this after looking through the Runtime Deploy Tool messages when I connect to an AMD64 architecture Successfully Connected to Target ( {MyIP} - AMD64 ) when I connect to an ARM64 architecture (Raspberry Pi5) Successfully Connected to Target ( {MyIP} - ) As clearly seen in the attached .png, the AMD64 target is detected, while the ARM64 target architecture is not detected (displayed). I assume that this is the reason why the pulldown menu isn't populated correctly.

Hello all, I am extremely new to Codesys and to programming with these languages in general. I have an HMI panel with 8 physical buttons to the right side of it. I am trying to have these set to change the visualization to a specific screen which I have designed 8 of. I currently have "use CurrentVisu" enabled in the visualization manager. I also have input blocks with all of the buttons being directed to output blocks which I want to have as the switcher for the visualization. Picture is attached for what I have currently. This could be the wrong approach to this issue. Any help is much appreciated.

Post by andrea199403 on Assigning Modbus addresses to a structure in a dynamic way

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.

I am having an issue where the manual start/stop push buttons on the HMI are supposed to take the pumps/blowers out of auto. The logic I have attached works for the pumps, but not the blower. From what I can tell it is the exact same logic, but it is not writing a 0 to the Auto PB variable. Attached is the logic, cross reference list to show nothing else is writing to it, and the HMI screen. Any help? Am I missing something? I am using a Groov Epic PR1, my software version is 3.5 SP19 Patch 5 32 Bit.

What happened to Python? Iβve just installed version 3.5.21.3 of the CODESYS development environment. Iβm coming from 3.5.19.5. What happened to Python scripting! We rely heavily on it for the automatic generation of thousands of lines of code! It seems absurd to me that such an important feature has been removed!

Interesting, thanks! Didnt know about ANY before, and will sure find a use-case for it. Im not sure it will help me here though, it seems to me that an ANY will not accept a string assignment? I actually think that the "ALIAS" should work, that was a hard found error. I had a fair bit of scratching my head looking for misdirected pointers before I understood what was (not) happening. I will use the work-around of individual structs instead.

Hi, I'm experiencing a bug with the latest version of SoftMotion CNC library (4.17), where the 3DPath object in Visu is missing all the important properties. I've verified that a previous app I was working on with library version 4.16 did not have this issue and the issue is duplicated in that project when I update it to 4.17. I've already submitted a bug report, but for the time being I need to revert the project I'm currently working on back a revision. I've tried right clicking on the library but the option to select the version is greyed out. Can anyone help me?

Use a VAR_INPUT for properties. The reason for the error is that you can't get a reference to a property. Using a VAR_INPUT will copy the property to an input variable.

To prevent ambiguous use of this enumeration value. Let's say another ENUM is available in your project or in another library which has an enumeration value AM_WRITE, then it is not clear which AM_WRITE you want to assign. By this qualified access to the SysFile.AM_WRITE, it is completely clear for the compiler.

I have the same annoying problem. The confirmation prompt for every single action appeared recently after an update from CODESYS 3.5 SP20 Patch 3 to Patch4, but I don't think it's due to this. Having to confirm every operation while debugging an application is a considerable waste of time and does not help at all to concentrate on development, not to mention that many times you miss the long-awaited event because you are busy looking for the 'yes' button to resume debugging or force a variable. Does anyone know how to disable the confirmation messages?

Hello, Depends on the architecture of your PLC. If the PLC is a PC-based item with a normal desktop environment, then you probably can. I find it simpler to install an IIoT Router in the panel, and use an encripted VPN to link to my office PC / Laptop on demand.

you are able to do this all in one screen. It is possible to set the rights of every element to visible but not editable for the user "none". so everyone is able to see this elements, but can't do any changes. At the login button you set the rights to editable for the user "none" to be able to go to the login. Every element that should be hidden before logging in, set the rights visible and editable only for "higher" users. Hint: to change rights you are able to select more then one element and edit rights for all at the same time. Saves a lot of time! Good luck!

Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard

So it's currently mapped to an array of BYTES? Can you create a UNION? TYPE sBytesString : UNION AsBytes: ARRAY[0..127] OF BYTE; AsString: STRING(128); END_UNION END_TYPE Map it to the bytes, read it in the STRING!

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
