Post by bbm1995 on Security Screen - Custom Certificates for OPC UA Server? ^{CODESYS Forge talk (Post)}
Hi everyone, is it possible to use selfsigned/created certificates (eg. with X - Certificate and Key Management) as a OPC UA Server certificate in the Security Screen? As far as I know I can only upload client certificates to the PLC and move it to "Trusted", "Untrusted" and "Quarantined". Same question is on sps-forum.de

Seems like you use SIZEOF as size, but you need to use LEN as size of data which you want to write.

Hi, How can you access the <root> of the Linux system? I'm struggling with this as the code above results in an invalid handle, as it cannot access '/'.</root> I am using Control for Raspberry Pi for context. Thanks.

Post by mp9876 on Problem using MeasureFrequence FB ^{CODESYS Forge talk (Post)}
Hi everyone, new at Codesys and PLC programming in general. I am using Codesys Win V3.5 SP20 I would like to measure an encoder's frequency output (obtaining that pulse train from Factory IO) and intended to use the MeasureFrequence FB (Intern/CAA/Utilities/CAA Mathematics/3.5.19.0). As mentioned in the title what I need to measure is low frequency, such as lower than 40hz (a cycle every 25mS) or so; I could even go lower frequency if required as this is for test purposes) therefore I am not expecting problem measuring a low frequency with that FB The library in question appears to be installed as I can retrieve it from the Library Repository. I can also see it from the Device's Library Manager. Problem arises when I am trying to instantiate this particular FB. I go like this: VAR MeasF:MeasureFrequence; END_VAR Please note that as soon as I start typing the "MeasureFrequence", the MeasureFrequence comes out as a viable option in auto-typing; seems to indicate that the FB is recognized somehow. But there is no way I can compile this as it comes back with the following: C0046: Identifier 'MeasureFrequence' not defined. Tried to rename that to ABC instead of MeasF; same issue. Possibly that the library is not properly installed ? Placeholder ? I would greatly appreciate a bit of guidance if possible. Thank you and regards, Mike

Hi We have picked up an issue OSCAT_BASIC.Scale_r function call not working in the old lad and FBD version 4.60. Gives no output on the function call. When we convert this to LAD2 it works. As can be see by the two screenshot in normal LD not working in LAD2 it works. Please confirm if this is an issue with Oscat or with LAD in 3.5.21sp3, is there an workaround. Regards Shaun

Post by levih on DocScripting ^{CODESYS Forge talk (Post)}
Hello I'm trying to use the DocScripting collection in Codesys. I've made it work on one PC(1) for the 3.5.16.4 version of the script collection. But when I try the same setup on another PC(2), I get an error message: Error loading Python DLL: D:\SCRIPTING\3.5.16.40\python27.dll (error code 14001) My setup on both PC's is thus: 1. Downloaded and installed Python 2. Copied the folder with the scripting collection to C: (because of admin rights) 3. Placed my .library file in the same folder as the scripting collection Only difference is that Python is v3.12.0 on PC1 and v3.12.1 on PC2. I thought maybe it was something with Python, but then I have tried using the scripting collection from 3.5.16.1, and that seems to work. Just not for scripting collection 3.5.16.4. I also can't seem to find any scripting collections on newer versions of Codesys? (e.g. 3.5.19.10) Thanks in advance!

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?

Post by macros8 on Translation - How to get text as reference in Frames translated? ^{CODESYS Forge talk (Post)}
Hi, one more point. I have been able to create Property of Text which is added to Global text list so it´s fine. But as soon as I use Frame configuration I lose all other properties but some very basics. I need to have still possibility to set Input configuration because my element is Button. Do you know how to make visible all standard properties + my own properties created in Frame configuration? Thanks a lot. M.
