Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Dear Forum I have the following config: Codesys_IDE 3.5.20 Codesys_Virtual_Control 4.13 Codesys_License_Server 4.13 I know these are not the newest versions, but in my mind these should work. I have the same problem here. I have the license server installed on the host, and in the docker container(Codesys virtual control) I'm able to ping the license server. In the /conf/codesyscontrol/CODESYSControl_User.cfg I have added the following config: [CmpCodeMeter] EnableNetLicenses=1 LicenseServer.1="ip address of the host" I have tried it via the wbm web-page. I can create new license containers over there, but still no luck. I also have tried to run the docker container with the -s "server_IP" command. I have searched for some tutorial's but I couldn't find it. If anyone has some clue or can give me a push in the right direction it would be very very welcome!

Post by sumit on Remote Ethernet/ip Adapter communication with scanner running on codesys ^{CODESYS Forge talk (Post)}
Hello there, I have my ethernet/ip adapter (from Texas Instrument) running on Texas Instrument Board and I have configured the scanner on codesys. I have mapped the I/Os and I can see (on wireshark) the frames coming from adapter but I don't see my input variables in scanner get updated, they just stay at 0. I wanted to see the real data that has been sent from adapter to scanner on codesys. I am not sure if the problem is in I/O mapping or there is a step/s that I have missed. I have attached the screenshot of my project for your ref. Thank you, Sumit

Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP) ^{CODESYS Forge talk (Post)}
I came up with an FBD that seems to be working, although it may not be a true Retriggerable Pulse timer. There may be some delay associated with the two MOVE functions and ADD function I incorporated. I'd be interested if anyone is able to come up with something cleaner. I am surprised that this is not a built-in function block of the CodeSYS library. This is a common feature of multi-function timer relays. I also attached a page from the cut sheet of a Schneider relay that shows 10 timing functions. Looks like the CodeSYS library has built-in function blocks for only 3 of the 10.

Post by fdmartello on Unable to compare projects containing alarm manager 4.5.0.0 ^{CODESYS Forge talk (Post)}
Hello. In Codesys version 3.5.19.50 when comparing two projects that have an "Alarm Configuration" obj from the Alarm Manager library vers. 4.5.0.0 the attached error pops up. This originally happened with two projects that I converted from vers. 3.5.17.30 so, thinking it was some conversion issue, I created two clean projects directly in 3.5.19.50 using the Standard Project template and only added the Alarm Configuration objects in them. The result is the same and the only way I found that allowed me to compare them is by deleting the incriminated object in one of the two projects. Has anyone else encountered this issue? Best regards

Post by arundara on OPC UA Server Stops after 5 consecutive disconnections of ethernet port ^{CODESYS Forge talk (Post)}
Hello Every one, During testing of OPC UA communication between UA Expert software and the CODESYS SoftPLC on a Linux environment, an observation was made. When the Ethernet cable was disconnected and reconnected with 2-minute intervals, on the 5th attempt, the OPC UA connection failed to establish in UA Expert software. At this juncture, restarting the CODESYS SoftPLC enabled the reestablishment of OPC UA communication. The same result was obtained when testing on a Raspberry Pi SoftPLC. What is the reason behind this phenomenon? and whether there are settings to stop this behavior? Please help. Thanks & Regards.

Epis doesnt want Softmotion. I thought it was about the price. If it was possible it would be working already and i dont need an extra licence. Thats the problem of codesys. The software is running but hangs on its license. Epis made it posible to see the stick. I can see the license. Softmotion is there from 3.5.14.Xx Like is said And Motion control is alrady posible 15 year ago. And i only need a Sync of 2 drives. I want a good solution not a refund. Dont point to the manufacturer. The software is made by 3s not by epis .

Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
Thanks for the response, as I've thought about this problem over the last month I began to suspect this was a problem with not being able to exactly represent .1 as a 32 bit binary number. I think I've found a work around by making the number an integer, then dividing it by 10 and storing that value as a floating point number. There is still an issue with the value not being exact somewhere in the 8th or 9th decimal place, but because I'm incrementing an integer value then dividing it, the error doesn't compound.

Post by jaspergain on Non-existing identifiers ^{CODESYS Forge talk (Post)}
Hello, I got a bit of a weird issue going on which is kind of annoying. So recently we switched a lot of Modbus IO to EtherCAT, as we were having issues with stability. All works fine, which is great. But sometimes when I change the program I get errors claiming that identifiers are not defined. Meaning I can't go online. See the picture below. I believe this is because some of these identifiers were used with Modbus, and they weren't properly removed/deleted? A clean all temporary fixes the issue, but it comes back again after a while of changing the code, and building. Any way to fix these non-existing required identifiers, or even find out where they are required? Thanks for the help in advance. Jasper.

Post by kuegerls on SysProcessExecuteCommand2 and CANopen Device ^{CODESYS Forge talk (Post)}
Hello, CODESYS Control is running on my RevPi, and my system communicates over a CANbus with a master using the ConnectCan module (Slave - CANopen Device). The communication works perfectly fine so far. However, as soon as I call a Python script with "SysProcessExecuteCommand2" that creates a CSV file and executes without errors, the master does not adopt any changes to the Transmission Process Data Objects (TPDOs). I don't quite understand what one has to do with the other, and perhaps someone can help me with this. Here is my script call: SysProcess.SysProcessExecuteCommand2(pszCommand:='python /home/pi/test.py', pszStdOut:=sCMDOutput, udiStdOutLen:= SIZEOF(sCMDOutput), pResult := ADR(eResult)); Thank you in advance!

Hi, We are working to provide our customers with CODESYS operation on our hardware product ( https://elprotech.com/product/el-qe-e-quantum-edge-series/ ). I'm trying to enable a CODESYS license (Soft container) on our product running ARM64 linux. This problem am having looks similar to here: https://forge.codesys.com/forge/talk/Runtime/thread/6d29b6b4de/ and here: https://forge.codesys.com/forge/talk/Runtime/thread/a2d0c63375/; but I am not running docker, and I am not re-installing a license. This is first time install. I have CODESYS Control SL running on my device, as well as CodeMeter.

Hi There, For my understanding: are you trying to display the contents of a text list in an alarm message based on the id? For example, you could maintain a text list of common alarm messages, and then display based on which message is true?

Thanks for your response! It seems like the VisuElems library has updated functions to the ones you used but apparently these older ones still work, even if I couldn't find them in the library documentation and they are also not suggested automatically by Codesys (when using Ctrl + Space). However, its precisely what I was looking for and it works. Thanks!

Post by i-campbell on Official MQTT-Client: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED ^{CODESYS Forge talk (Post)}
I can't answer why it's not resetting, but from the description of g_udiMaxReceiveBufferSize, I would guess the sum of sizes of the mqtt packets received in one cycle exceeded this value. So the answer may be to increase that parameter. https://content.helpme-codesys.com/en/libs/MQTT%20Client%20SL/Current/MQTT-Client/Common/Params/MQTTParam.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_library_parameter.html

If it still does not work, try it first without the muxboard. PS: Note the channel assignment. Muxboard 0 = I2C_Master 1,0,0,0,0,0,0,0 Muxboard 1 = I2C_Master 2,0,0,0,0,0,0,0 etc.
