Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
maybe this would be a better approach, then you don't have to pass the constant at all. FUNCTION fun : INT VAR_IN_OUT arr: ARRAY[*] OF INT; END_VAR VAR lower: DINT; upper: DINT; END_VAR lower:= LOWER_BOUND(arr, 1); upper:= UPPER_BOUND(arr, 1); see here as well https://help.codesys.com/api-content/2/codesys/3.5.12.0/en/_cds_datatype_array/

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.

Hi, I have got a solution. Go to local disk C. (There will be an option View on top. Click View>Show>hidden items.) go to following path:C:\ProgramData\CODESYS\CODESYSControlWinV3x64 there will be one or two files. delete it and run control win again. issue will be resolved.

Post by masmith1553 on SDO generation ^{CODESYS Forge talk (Post)}
If you add any device to the CANOpen Manager it will send messages to verify the device is on the network. Do you have the Enable expert settings check box checked in the General tab? have you added any SDOs in the SDOs tab? I avoid using the CANOpen Manager and just use the CAN_Tx and CAN_Rx blocks from the library.

Post by eschwellinger on New Ladder Diagram conversion does not work due to missing features ^{CODESYS Forge talk (Post)}
The "remove unused" parameters have been added to 1.0 version as well as the "manual" removal of pins... also allowed "empty" inputs for blocks is in and the compile error described there should no longer occurs. Drag drop of variables is not yet implemented and I don't think the double-click feature yet either.

Today I was struggling with the same problem. in search for a solution i found this thread. Then i tried some things. It doesn't seem to be just a libraries' fault. In addition to 3.5.19, we also have a 3.5.18 version installed, the library versions of Modbus_TCP_Master and Modbus_TCP_Slave are the same, but more than 10 slave channels can be added in 3.5.18

If my application does some kind of violation which makes it cast an exception it will trigger my real watchdog which results in a reboot. Unfortunately the log it seems only shows the boot sequence. Is it possible to see what happen before reboot?

Do any of you have an idea?

Hello, our team is able to use Raspberry Pi on CODESYS, but we purchased two peripherals that utilize I2C and we cannot figure out how to access these devices in CODESYS. But they are working using Python. Does anyone have a suggestion or an existing library that might help support this? Thank you, Jeff

Post by bjarne-pagaard on Multiple WebVisu ^{CODESYS Forge talk (Post)}
You can use the switch frame variable, but there should be a variable for each active visu user. You can put the switch frame variable in an array, and use CURRENTCLIENTID as index into the array to get what you want. The CURRENTCLIENTID is assigned to new users automagically by the Visu Management.

Hi, thanks a lot for the response. I did check all these parameters, but if the PlanningTask takes up to 60 ms, I can't increase the Buffer to such values. I contacted the Codesys support with a projectarchive. Let's see if they can help. Thanks again for your great support!

Hi, I'm experiencing this problem as well. Did the suggested combination resolve your issues in the end? If not, I can stop my efforts rolling back to these versions. I'm trying to get CC for RPi 4.8.0.0 installed on the device, but I can't find it after installing it through the packet manager.

from another post on this forum .... In your library project select Project -> Project Information. On the Properties table remove the "LanguageModelAttribute" Value "Qualified Access Only". This will allow you to access the object without qualifying the access. ...... I guess they've compiled it the library with that setting and now I need to mess around with versions.

Post by phoward131 on Numpad decimal value requires leading zero ^{CODESYS Forge talk (Post)}
I have noticed on the standard numpad dialog, if a user enters a purely decimal number (ie '.6'), the numpad will not accept the value but gives no indication. One must type a leading zero (ie '0.6') in order for it to work. Is there a way to correct this so that a user can just type the decimal value?
