Post by corriibme on Setting array values with JSON Utilities SL ^{CODESYS Forge talk (Post)}
It turns out that you can build JSON structures without ever calling the JSONBuilder function block directly. Instead, create a pointer to JSON.JSONData and invoke the necessary methods on its dereference. The parent object has a parent index of -1 (and an index of 0). EVERY other item (including keys, values, empty arrays and sub-objects) created by the setX methods needs the index to increase by 1. Then use the JSONByteArrayWriter FB to generate your JSON string

Post by wiresplus on Display minutes as hours & minutes ^{CODESYS Forge talk (Post)}
Hello, I have a counter that increments an INT value once per minute I want to display this value in Minutes until 60, then Hours/Minutes thereafter on the HMI Codesys V3.5 SP16 I can divide the minutes by 60 to get hours, but then the minutes is still more than 60. Example: a process has run for 350 Minutes. I need to display "5 Hours 50 Minutes" But if it's only been 45 Minutes, I don't want "0 Hours 45 Minutes" , just "45 Minutes"

Post by ph0010421 on General question about library versions ^{CODESYS Forge talk (Post)}
Hello I can't find anything to read on the subject so I'll ask here. Up to now, when adding a (for example) Modbus Master, I've selected the version <= the RT version, so if I'm using SP13 Patch 3, I can use a library that doesn't exceed this. I've no idea if this is correct, but it's always worked. Can someone explain the 4.x.x.x libraries that have appeared; are they tied to a RT version? The controller I use is now at SP18Patch60, so should I continue to use 3.5.xxx or change? thanks

Post by nelsonreis on Help with IFM EcomatController CR710S in Codesys ^{CODESYS Forge talk (Post)}
Hi, Recently I bought a CR710S controller from IFM. I installed Codesys V3.5 SP11 as recommended and all required packages (including the safety packages and the IOWrapper package). However, I can't even open the project template without getting errors related to libraries failing to load (below in the first print screen). Then, clicking ok appears only 2 errors (second print) and when trying to go to simulation and login I get another 2 different errors (third print). I really appreciate any help anyone can provide, I'm completely stuck on this right now.

Hello New W11 machine. I've tried installing and the 'Codesys installer' appeared, which basically failed. This was the exe from the Store. I've now tried installing with an old copy of SP17, which didn't try and use the Codesys installer, but has hung at the 'Install all packages added to the setup' stage. Has the exe been updated to use the Codesys installer? What is the installer? Do we think it'll work on w11? thanks, Paul

Post by wollvieh on License Activation Problems ^{CODESYS Forge talk (Post)}
on a raspberry pi delete the folder and its content before licensing. /var/opt/codesys/cmactlicense If you plug this SD card in another raspi ( which has another hw-serial number) you'll get a second empty softcontainer. This could lead to an unlicensed PFC (it could only handle one container) The solution is: To delete the /var/opt/codesys/cmactlicense directory and content of it and then aktivate the lizenz via WibuCmRau file and Lizenzmanager.

Hello, I'm asking for help with installing the license server for Linux SL 4.18.0.0. When I try to install it, I get a message that the WIBUCodeMeter package is missing. I checked the package manager tab to see if the package is installed, and it is - Codemeter 8.40.7120.501. I've checked the CodeMeter Runtime on the target machine, and everything seems to be working fine. One thing caught my eye: the Device Architecture tab says "None" Please help me solve this problem.

I'm using Codesys v3.21SP4 on my PC via ControlWin to establish CAN communication through the PC's USB port. The software works fine. The CAN/USB converter works fine and is validated. However, there is no communication. Which folder and file should be modified to allow the CAN/USB converter to work and thus achieve the connection? Converter used: PCAN-View Information not yet processed: Access the folder: C:\Program Files (x86)\3S CODESYS\GatewayPLC\CODESYSControl.cfg Uncomment the line: Component.5=CmpPCANBasicDrv Any help would be appreciated.

Post by timvh on History of Alarms ^{CODESYS Forge talk (Post)}
It is most likely related to the existing alarm log files in the Control Win. Depending on how you start up the Control Win, you can find the files in: C:\Users\<user name="">\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\<unique id="">\PlcLogic\alarms\ Or C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\<unique id="">\PlcLogic\alarms\</unique></unique></user> Delete the files in this folder, download your project again and start the application. PS, if you have an older version of CODESYS, the files are in: C:\ProgramData\CODESYS\CODESYSControlWinV3x64\<unique id="">\PlcLogic\alarms</unique>

Post by timvh on OPC UA PubSub SL 1.3 — UADP WriterGroup with assigned PSS.SecurityGroup still publishes plaintext ^{CODESYS Forge talk (Post)}
I never tried this, but maybe you need to create a certificate on the controller for this? See the menu View - Security Screen. Select the device and see if you need to create a certificate. And maybe you also need to accept the certificate of the other device. This can also be done in the security screen. PS, the CODESYS Runtime Control version must be greater than 3.5.21.0.

Post by seler on Custom button with output status ^{CODESYS Forge talk (Post)}
Just to clarify. Output for lamp will have two inputs: from plc IN (wall switch) and from visu button. Until now I had separate object for visu button and separate for visu lamp. Now I want it to be one object, bulb icone which will change color on lamp status and yet by touching it will change visu button state. Tried "Switch Image" object but there is no way to assign switch var.

Post by gseidel on Axis directions in CNC editor not using right-hand rule? ^{CODESYS Forge talk (Post)}
Hi bertus, the coordinate systems used in SoftMotion CNC are all right-handed. The CNC editor uses isometric projection. This can be confusing, as in your example. The y-axis seems to point into the screen, away from the viewer. However, this is just an optical effect. If you turn on the (experimental) perspective projection (must be added to the CNC tool bar using tools->customize), you can see that the coordinate system is in fact right-handed. Best regards, Georg

But it only shows the message of the active alarms. In the history the message is empty (also in the .csv Export file). The archiving in the alarm group is checked and the Alarm storage is activated. I'm using the Version V3.5 SP22 Patch 1. Do you have any idea where that comes from?

Thanks for your reply @eschwellinger. Update : the is problem is resolved. It was done by renaming the User database file (/var/opt/codesys/.UserDatabase.csv) as deleting it was risky. After restart the IDE asked me to create new user. On doing that the problem got resolved. Reference for members facing similar problem/s : sudo systemctl stop codesyscontrol sudo mv /var/opt/codesys/.UserDatabase.csv_ /var/opt/codesys/.UserDatabase.csv_.old sudo systemctl start codesyscontrol

Post by dhumphries on Codesys Installation problem ^{CODESYS Forge talk (Post)}
Installing codesys has been the biggest point of frustration for me and is the reason I'm currently working on building a VM just for the codesys engineering software so once I get a working installation I can copy the VM to new workstations instead of fighting with the installer every time I get a workstation upgrade. The best advice I've gotten in the past is to uninstall everything and start over, this is successful 50% of the time. Also don't install the latest version it's usually less stable than an older one ironically.

Post by gseidel on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
Dear Mr. Kolev, can you please explain a little more: what happens at an STO? I assume the slave axes will be stopped and retain their current position? How, then, do you call MC_CamIn after the STO? Do you restart it with a new rising edge, but on the same master position as before the STO? Which StartMode are you using, is the cam slave absolute or relative, master absolute or relative? Are the slave axes modulo or finite axes? Best regards, Georg Seidel
