Hello @eschwellinger, Why not using one of those 2 folders: C:\ProgramData\CODESYS C:\Users\Public\Documents\CODESYS The main reason is depending on the company and the user right, the end user may not have the access to use those folders. Also having a non version dependent folder may help if the end user uninstall a previous version and forgot all its sample project where in this previous version installation. Thanks.

Post by andre-luis on Check if Codesys runtime is on 'Running' or 'Stopped' state? ^{CODESYS Forge talk (Post)}
Just to share, for those who as me are seeking for this and had found no information anywhere in this World: Every time I stop/start the PLC runtime ( turning into 'Stopped' or 'Running' state ) the 'CODESYSControlService' appears at the Taskmanager list, which could suggest a straight correlation. I was expecting a clever solution, but this one solves for while.

Post by totorovic on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
However, if faulty EtherCAT cables were the issue, why wouldn't the error occur during normal operation? Why would bad cables only cause problems during a hard shutdown? I don't have the answer to this question. One last question: When you encountered this behavior, did you see a similar error in your logs? i.e, an "AccessViolation" exception in the EtherCAT Task Yes. It was the exeption you can see in attached file.

Post by pixsys on Webvisu cliënt responsiveness ^{CODESYS Forge talk (Post)}
Hi, please check if "Support client animations and overlay of native elements" option is enabled. This option is very heavy to manage for the Webclients. I'm using the Pixsys srl "TC series" HMI with the code "P3" (so a 4+4 cores CPU) that runs very well also with this option active. The same CPU is mounted also in their WebPanel "WP" series, so you can try one of them if you want.

Post by kuegerls on OpC UA server on Raspberry Pi MC SL - Certificate Issue ^{CODESYS Forge talk (Post)}
Hello, I have set up an OPC UA server following several guides, including this one: https://revolutionpi.com/documentation/tutorials/opc-ua-codesys-nodered/. The license for the runtime is installed on the device. However, I am unable to create a certificate for the OPC UA server in the security screen. I always get the error message: "The certificate has not been created by the device." Does anyone have an idea what might be causing this issue? Any help would be greatly appreciated! Thanks in advance! Best regards, Stefan

Post by installwhat on Ethercat and profinet on together ^{CODESYS Forge talk (Post)}
I'm curious about the impact of having profinet and Ethercat (specifically softmotion so frame at start of task?) running together. Since it's advised to access the data from the bus task should have both profinet io and ethercat on the same task? Are there any implications around this one should be aware of especially since the frame at task start is just, so far as I'm aware, an ethercat thing? Thanks

Post by andrax on Mux I2C ^{CODESYS Forge talk (Post)}
the TCA9548a does not work in Codesys. In Pyton this is only queried once and in Codesys cyclically. Of course you can also insert a terminating resistor in each port, then you should have no problems. I use this one: https://botland.de/8-bit-multiplexer/12723-qwiic-mux-breakout-8-kanal-modul-mit-i2c-multiplexer-tca9548a-sparkfun-bob-16784-5904422341428.html You can simply set the library to the latest version. You do not need Oscat. Do you need an example project for the BMP280?

I'm getting this error on one of my projects. Searching for it I came across this https://www.codesys.com/fileadmin/data/Images/System/Releaseinformation/Patch-Note-CODESYS-Visualization-4300.html which says it was a bug VIS-1394, fixed in Visualization 4.3.0.0. I'm using a previous visu version, what is the cause of this error, and what can be done to work around it?

Post by camilloo on Control for Linux SL on Ubuntu Core ^{CODESYS Forge talk (Post)}
(dhumphries) I followed your advice and tried it on Ubuntu Server. Was a good choice. Your material was also very helpful :). Thanks for Your help! I no longer have problems connecting to Ubuntu. However, I still cannot install Virtual PLC. I'm currently getting a missing path message: "C:\Program Files\CODESYS 3.5.19.60\CODESYS\CODESYS Virtual Control for Linux SL\Delivery\virtuallinux\VirtualControlAPI.py." It looks as the package: "CODESYS Virtual Control for Linux SL" was not installed. But, there isn't one in CODESYS Store or I'm doing something incorrectly.

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
Is there a way that I can create a variable in a GVL that I can control with logic but a user can not put a force on this variable. I have looked at the access rights but this seems to only limit editing the GVL or POU. This variable will only be assigned a value in one POU but it will be used throughout many other POUs.

Post by tib0r on c2iec - translating C to ST ^{CODESYS Forge talk (Post)}
I was looking for a transpiler from some more widely used general programming language into ST. It was not easy but I found this :) https://forge.codesys.com/tol/c2iec/home/Home/ Does anybody use it for a programm/library of a couple of hundred lines or more? How does one go about using the output? Is there a “converter” into the Codesys IDE? PLCOpenXML? Would there be interest in this? tib0r

Post by timvh on Codesys SVN ^{CODESYS Forge talk (Post)}
If you use 3.5 SP10, then Git is not supported. SVN will work fine, but with this version you do need a USB key, because software licenses are not supported with this version. Off course you can work without SVN (or Git), but especially if you work with multiple developers on one project, it will save you a lot of time and you can keep track of all changes and improvements much easier. So how much is this worth to you?

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
All Sensors from the OneWire Master are assigned already to a seperate task with low prio (26) that runs with 1s cycle time. My EtherCat Task is running with Prio 1. It all works fine, until I adjust the CODESYScontrol.cfg or the CODESYScontrol_Usr.cfg files so that it supports a 2nd OneWire Master in the Codeys Runtime. If I change something in this config file and reboot my EtherCat Master stops working.
