Post by alex2 on Codesys SVN ^{CODESYS Forge talk (Post)}
Hello Everyone. I have a question about the SVN module on Codesys. I am using Codesys V3.5.10 and installed Codesys SVN 4.2.5.1 but when i try to connect my SVN to codesys i have a message saying that there is no license for accessing the Url. I searched on the codesys store and it seems that "CODESYS Professional Developer Edition" is needed? Am i right? Do i also need to buy a USB key? Is there another edition but only for the SVN? I thank you in advance for your answers.

Post by richard-wang on Codesys recipe manager - what does it do? ^{CODESYS Forge talk (Post)}
Hi All Thanks for sharing this information. For whom may not know why always get error code 16#4000 or 16#4002 while performing Recipe commands, the root cause is There is a line need to be inserted in CODESYSControl.cfg file, which is PlaceholderFilePath.1=/var/opt/codesys/PlcLogic/ I am using Pi, therefore the above path is set to my pi unit, after adding above line to my cfg file, all the Recipe commands work fine. But I still do not know how and when this file got modified though.

Update: I started over. I saved progress at each step. all compiled zero errors, zero warnings. Pre-processor messages remain, but I can make progress. Until I try to re- load the project file in Codesys. Re-loaded files error as above when compiled, even though they compiled error-free immediately before saving. Is my installation borked? (Not easy to re-install due to IT madness...)

Post by ndzied2 on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
This is a consequence of how computers store floating point numbers. 0.1 cannot be exactly represented in a computer. This is not a CoDeSys thing. Here is a link to a converter to show you the exact value that is represented when you use a REAL data type (which is a 32 bit float). https://baseconvert.com/ieee-754-floating-point If you really need to keep track of 0.1 increments. use INT OR DINT and then add 1 each time and assume that there is one decimal place.

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 rabaggett on No Visu on RasPi ^{CODESYS Forge talk (Post)}
OK, I got this to work as shown above in mos89p's comment. What I did: Tools/Update Raspberry Pi. Reloading the runtime seems to have solved the web problem. I can view the visualization on the Pi and laptop using a browser as shown above. Thanks! But Isn't the visualization supposed to take over the screen of the Raspi? When I run visu projects on Windows or Wago, the visualization shows on that device's screen by default.. But this is not happening in this case

Post by sajid on NMEA Serial data read in Control win v3 x64 ^{CODESYS Forge talk (Post)}
I am using the SerialCom example program from the CODESYS website to read NMEA strings in CODESYS Control Win V3 x64 through a serial-to-USB converter. However, I occasionally receive only partial data or encounter errors in the received string. A screenshot of expected NMEA string attached for reference. Could you please advise on how to ensure the full NMEA string is received consistently? Error in strRead variable is <value of="" the="" expression="" cannot="" be="" retrieved=""></value>

Hello, I am using an Inovance PLC to control a servo via EtherCAT. When I enable MC_POWER, the drive switches to Run mode successfully. After that I call MC_MoveRelative, but I get the error SMC_FB_WASNT_CALLED_DURING_MOTION. The servo vibrates but the motor shaft does not move. I am new to EtherCAT/servo motion control, so I would appreciate any guidance or suggestions for troubleshooting this issue. Thank you in advance for your help.

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.

Hi Georg OK got it, thank you. I respect your (CODESYS) policies on that issue. Will try to update according to your recommondation if the customer experience same error in the future. Though - from within my coding heart it does bother me deeply, that I cannot get further understanging/knowledge on the iPhasingState, but I guees I will have to swollow that bitter pill and get on with it! hehe ;-)

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 antonz on OSCAT Scale_r function not working in LD 4.60 works in LAD2 on 3.5.21sp3 ^{CODESYS Forge talk (Post)}
That's what I found as well Shaun. I have seen it at least in versions 3.5.21.1 and 3.5.21.3. There seems to be an issue with the FBD/LD package v4.6.0.0. The workaround proposed by Tim works but needs to be done manually on every code change/addition. For now we manually downgrade the FBD/LD package from v4.6.0.0 down to v4.5.0.0 after installation of CoDeSys. Same as you did. I hope this gets fixed on a next patch.

Post by msirotkin on EtherCAT status errors ^{CODESYS Forge talk (Post)}
Didn't help. I'm just trying to understand why the errors occur. Are they from the poor driver or from the Linux network stack. That's why I wanted to know how the rxerros and lostframes are counted. Because in other places (like ethtool info) there are no any issues. And the Ethercat device works fine. And it also strange that on the second ethernet port with a different HW and driver Ethercat works better, but still time to time gets such errors.

Post by rtlman on Scan devices hangs CODESYS ^{CODESYS Forge talk (Post)}
Hello, I have a problem that randomly appeared today. When trying to scan a network adapter in "Deploy Control SL" the whole program hangs and needs to be restarted. I have been running "CODESYS v3.5 SP21 Patch 3" for a while and it has worked without any issues until now. I've tried upgrading to "CODESYS v3.5 SP21 Patch 4" with the same result. I've not made any system settings recently that im aware of which could cause this. Has anybody had similar a issue?

Post by farren on Codesys complains about matching versions ^{CODESYS Forge talk (Post)}
I'm building up a 2nd PC to match an existing developer PC. Installed the same SP and Patch levels but when I open a project that was created on the existing PC, Codesys complains that it's not the same version. Attaching a screenshot..... What else is there to match? Also, can all of the libraries that are on the existing machine be copied from it to the new machine and if so, how? (So I get the same versions) Which files/folders do I copy? Thanks! -Farren

Post by josepmariarams on Limit Axis CNC Jerk using SMC_Polynomial_AbsMaxLocs ^{CODESYS Forge talk (Post)}
Dears. Until now, I have been using CNC libraries with Codesys 3.5SP11. I was using SMC_Polynomial_AbsMaxLocs function, from CNC library, to calculate the axis jerks, interpolating splines, to limit it. Now I have passed to SP20, and the functions which calculates the zeros and the maximum-minimum and zeros of polynomials has been disapeared. Questions: -Exist any FB wich can limit the jerk of individual axis in CNC? -Exist any other functions which can calculate max-min and zeros of polynomials? Thanks

Now when we're opening an project thats's not opend before on my pc and we're not sure in witch version it's made it's quite annoying. We don't want to update to the newest version. Is there a way that it's automatic opening the correct version? Is there a program/tool/easy way to do this? Thanks,

Post by nulltrace on How change Unity-ID in TCP Modbus Slave ^{CODESYS Forge talk (Post)}
Please explain how you configured that. Normaly, the Server should answer to all UID as long as gateway isn't activated. With activated gateway all UID will be forwarded to Serial-Interface, in taht case 255 has to be used for Gateway-Diagnostics. So that means, there is somethink wrong on your configuration. Which CDS-Version, Which Runtime-Version and so on are used.
