Post by jzhvymetal77 on Special Chars in Visualizationfor QR code string ^{CODESYS Forge talk (Post)}
Ok, I got UTF-8 encoding working by encoding the full block character using [16#E2, 16#96, 16#88], which corresponds to U+2588 "█". Moving forward, I’ll use this for creating a QR code with Version 10-M (byte mode). This version allows up to 213 characters to be encoded.

Post by snhatton on OPC UA: How to change NodeId ?! ^{CODESYS Forge talk (Post)}
You can change the node id by adding the following to /etc/CODESYSControl.cfg: [CmpOPCUAProviderIecVarAccess] CustomNodeName=MyPLC123 Then restart the runtime and the new Node name will appear with the connection. I don't know if it's possible to remove the |var| from the name. I hope this helps!

Post by ph0010421 on TCP/IP client ^{CODESYS Forge talk (Post)}
Hello TCIS_Send needs to be longer than 4 bytes because idata is 28 bytes long. There may be other ways, but I would make a UNION with string/array of bytes. Write your STRING into the AsString part then copy the AsBytes part into TCIS_Send (Elements [3] to [30]) then 252 would be in [31] (I've assumed the idata is always the same length)

Post by ulad on SPI Communication ^{CODESYS Forge talk (Post)}
Hello. I created a project that uses SPI. This project is working well. I can see with an oscilloscope that the SPI pins are actually changing. But when I resave this project in the IDE and open it later in the system, I see a constant error. What do I need to fix? What am I doing wrong? Thank you.

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.

Post by lgeertsema on Checkbox font color in visualization style ^{CODESYS Forge talk (Post)}
Hello, I'm having a similar issue with buttons. I want to be able to set the default color and transparency of a button. I've tried a lot of different iterations like KNewman, but to no avail. Has there been some documentation released since KNewman posted this, or is the style editor still as undocumented as ever?

Hi Martin, I got the messagekey of the "upgrade format warning dialog" with key:"<< No Key>>". (please refer to the attachment) Is that means i can't use system.prompt_answers["<<No Key>>"] = PromptResult.OK; to auto-answer 'OK' in this dialog? Is there any other way to auto-answer this dialog? Thanks!

Post by wiresplus on Connect to remote PLC via local pc and teamviewer ^{CODESYS Forge talk (Post)}
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.

Post by hagroth on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
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

Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
Thank you for the response! It's a path I had already considered, however, while it has always worked for me on inputs, it doesn't on outputs, because if I enable the option to update all IOs at every scan, the IO tasks overwrite each other. However, I have found something very interesting which I am posting below.

Hello, I don't really know what my problem was, but it's working for me at the moment. All i did was to change my code because of some REAL_TO_INT conversions, like i wrote above. And later a complete new Pi setup (because of 64x support with 4.10.0.0 now).

I'll have a look at this, thanks. Do you maybe know why the C-integration doesn't work? I'm just curious because it was still some effort to create all these files. Ending up with a meaningless error feels very unsatisfying to me...

Post by durstloescher on Library Documentation DocScripting ^{CODESYS Forge talk (Post)}
Hi, I am currently creating a documentation for our library with DocScripting. In the process, I noticed that Visu images are created before the merge and transform, i.e. "screenshots" of the different Visus. Unfortunately, these are not used in the later process (Merge/Transform). Is there a way to set it up so that they are found in the html file?

Post by jaspergain on SoftMotion Axes issue ^{CODESYS Forge talk (Post)}
Dear, We have an issue with SoftMotion and it's licensing. We don't use SoftMotion in this project. But a SoftMotion license is required by it. The License metrics tell's us there is a -1 Axes. Is there a way to reset this? Delete this? There was a MotionControl device in the project, but we have deleted this. But it stayed at -1. Thanks for you help.

I have managed to change my dynamic visu table colors with the template for each column to dark like my rest of the webvisu background is. How ever the empty table (when not populated) and the table header stays white / gray. Is there same way to modify the colors of header and empty table?

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
Wow.... I missed this one in the manual - so there is a special syntax to invalidate a reference... Great :) Seems to work. (it's just mentionned in the examples line)... I've always assigned 0 to the variable, with := 0 - like setting a pointer to 0. In theory, that should work as well. Thanks!

Tell me, are there ways to remove the white background from the page loading? I want to change it to a black background. I think there are options with changing /home/codesys_root/PlcLogic/visu/webvisu.htm Perhaps you have already encountered a similar situation. I hope to find the answer to my question.

I'd like to measure tool length using SW. How do I set variable from the accurate drive position when switch turn ON/OFF? Hopefully, I'd like to measure Z-Pos with M-Function in G-Code automatically, And I'd like to set it to G43 as tool length correction.

Post by matt-purcell on Which Lib to use, connect to a socket with URL instead of IP address ^{CODESYS Forge talk (Post)}
I've been searching through these libraries, syssocket and net base services and they all seem to use the same structure for IP address for the connect function, SOCKADDRESS. At a glance, it doesn't look like that'll work, maybe it's just missing in the documentation somewhere?? I'm wondering if anyone has done it.
