You can try this setup: DINTVar := SHL(INT_TO_DINT (Low_Word_INT_Var),16) + INT_TO_DINT(High_Word_INT_Var);

Post by felipemsgarcia on Axis EtherCAT address ^{CODESYS Forge talk (Post)}
Hello, I'd like to write some parameters to axes from inside a function block where I passed axis by reference, using ETC_CO_SdoWrite. Is it possible to get the device address from inside the function block? Please see example below. Thank you!

Post by ph0010421 on Axis EtherCAT address ^{CODESYS Forge talk (Post)}
Hello SDO will write to the drive, not the axis, so you need to pass in the ethercat slave: VAR_IN_OUT Axis: IoDrvEthercatLib.ETCSlave; END_VAR Then you can get the address with: Axis.PhysSlaveAddr (as UINT)

Post by kevinm on Attaching Trace variable to Frame Configuration Variable ^{CODESYS Forge talk (Post)}
Is it possible to show a variable from a Frame Configuration in a Trace on that Visualization? I want to pass the FB for an AXIS_REF_ETC_SoE_Standard to the visualization and display live axis data in the visualization. However, I cannot find a way to use a Frame Configuration variable in the Trace Configuration dialog.

Post by jzhvymetal77 on VarAccGetAddress does not return the correct address for TYPE_ARRAY or TYPE_USERDEF. ^{CODESYS Forge talk (Post)}
VarAccGetAddress does not return the correct address for TYPE_ARRAY or TYPE_USERDEF. When you use VarAccGetNode, it returns a proper IBaseTreeNode if you provide the full path of an array element or structure element, and it even provides the correct data type. The problem is that with TYPE_ARRAY, it returns the start address of the array rather than the indexed element. With TYPE_USERDEF, it only returns the offset of the element instead of the actual address. This causes many issues with nested structures or arrays of structures, since it requires manually calculating the address based on the parent IBaseTreeNode. See attached image and example.

Post by tokamk on Dynamic setting of the modbus tcp/ip slave ip address ^{CODESYS Forge talk (Post)}
Hello, I'm working on a project which includes Panel-PC which communicates with a PLC through Modbus TCP/IP. On the PLC I have a CODESYS code which has Modbus slave objects. The Modbus slave objects have to have manually set IP address in order for them to work properly and the Ip address has to be the PC-Panels's IP. This project is going to a customer and they're using their own IP address realm. So, my question is that is it possible to configure these slaves in some other way, so that the customer doesn't need to modify the CODESYS project? I was thinking that would it be possible to set the IP address of these slaves from external source?

Post by ojz0r on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
One thing you could do is create an object with the variable as field with a function and procedure to get the variable (read) and set the variable (write). These are then called from your program and the vizualization.

Post by andrax on Variable Length Array - Cannot mix variable and fixed length dimensions? ^{CODESYS Forge talk (Post)}
Arrays with variable lengths are a bad idea. This makes your system unstable and can lead to crashes. Declare your array large enough to reserve enough memory

Post by fless on See only variable ^{CODESYS Forge talk (Post)}
either you have "Insert with namespace" enabled in the SmartCoding options or your GVL_GLOBAL starts with {attribute 'qualified_only'} btw it's considered good practice to put the namespace in front of the variable. you could have variable with the same name in your PRG or FB.

Post by swol on HTML 5 - Controls -> Change Content-Security-Policy settings ^{CODESYS Forge talk (Post)}
Sorry for being late to the party... so it is not possible to use the webbrowser tool to display external websites in a visu anymore? As it is not possible to simply "adjust the ContentSecurityPolicyIncludeTrustedOrigins setting in the automatically generated webvisu.cfg.json file" as stated in the docs? We need to display data read from a Raspberry Pi (part of our computer network) in our webvisu. We used to do it by entering the Pi's IP address as the URL variable in the webbrowser element but now (I don't know since when, I'm new on the job) "The page’s settings blocked the loading of a resource (frame-src) at 'IP address' because it violates the following directive: “default-src 'self' 'unsafe-inline'”. What are the options for displaying the data?

Hello, I am encountering an interesting problem as below in SP20patch5 variable definition area. I think this is a bug. As can be seen in the attached screenshot, it assigns the same %MW or %QW address to all elements of the array. I hope Codesys team can solve this problem in the next version. Best regards, Imdat

Post by durallymax on Access Variable Visu Dialog ^{CODESYS Forge talk (Post)}
Is there a way to access the variable in the called dialog? Example: Text Field element with PLC_PRG.myVar as Text variable. OnMouseClick configured to write variable with keypad pop-up. OnValueChanged configured to Execute ST RND(PLC_PRG.myVar,2); Rather than change myVar with each copy of this Text Field, is there a way to access whatever the configured text variable is? Generally try to stay away from ST in visu, but was curious regardless.
