Post by amy123 on CSV Utility CANNOT_OPEN_DIRECTORY ^{CODESYS Forge talk (Post)}
Hello, I tried using the CSV Utility SL Example from the CODESYS IIoT Libraries SL. No matter what path I try, I can not get the InitSave to work from CSVWRitersSTExample, line 2. It always gives the error 'CANNOT_OPEN_DIRECTORY'. I am running this on an Windows Azure VM, with Codesys Control Win V3 x64. I added a folder called 'temp' to my C: so that the default 'C:/temp' would work. However it gives CANNOT_OPEN_DIRECTORY. I tried updating to 'C:\temp' with the same result. Any help would be greatly appreciated!

Post by kleeswi on SysFileOpen does not work after update to V3.5 SP19 Patch 5 ^{CODESYS Forge talk (Post)}
I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

Post by miodusy on File transfer via visu and codesys automation server ^{CODESYS Forge talk (Post)}
I have a problem with the file transfer library. Namely, it does not work via the codesys server. (error 5; overtime, and visualization resets). They operate mostly in local chains. I tested different browsers and VPN from the router. It works everywhere, except through access from the codesys automation server. The client, having many machines under one account, prefers to keep it that way rather than use an individual VPN just to download a backup. Does anyone have an idea what the problem is? Sylwester M.

Post by dagsupport on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard

Hi, When I try to install my codesys program with the new application-based licensing, I have an error "it exceeds the scope of the license agreement. See Device > Licensed Software Metrics" In the Licensed Software Metrics section, I see a code size < 3MB and less than 2700 variables in visualiaztions. I'm using a license "Control Basic L" with "Codesys Visualization L" option, so it should be enough with these metrics. What can I do ?

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.

Hello. I'm trying to use RecipeManCommands.ReloadRecipes Method for getting recipes from files. When I call the method it does not generate any error but also not reload any recipe to the recipe definition. Actually I have 6 recipe files on the directory PlcLogic. The rest of the methods work creating recipes, saving to file, etc. Does any one have the same issue? it is something to be set on the recipe manager?

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 robpqs on Visual error with cut/shredded texts ^{CODESYS Forge talk (Post)}
Hello, This is an old topic but it might help. This can/should be solved by either of the solution below 1. disabling the "Support client animations and overlay of native elements" option in the visualization Manager (which is handy) 2. disabling the "Hardware acceleration" of the browser. Saw it happening on some clients/PC and on other it works fine with the same webvisu... (Version 3.5.19.20 with visu package 4.4.0.0) Hopefully it will be fixed it in a next release. I haven't tested the 4.5.0.0 visu packages yet. RP,

Post by paro on "You are using inconsistent overlay settings, please check your compiler defines for the current application" error ^{CODESYS Forge talk (Post)}
Disable the setting "Support client animations and overlay of native elements" in the Visu Manager. Activating this setting should also set a compiler define (GENERATE_OVERLAY_VISU). Maybe the compiler define is set and the feature is not activated in the visu manager or or the other way round.. rightclick the Application -> Properties -> Build https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_properties_build.html

Post by joep on Custom robotics kinematics model debugging ^{CODESYS Forge talk (Post)}
When trying to move my axis using any group move instruction I get the following error: SMC_CP_INVALID_PATH_ELEM and axisgroup goes into errorstop state. I tested my methods thoroughly which makes it hard for me to debug. Are there some hidden rules I need to abide to? How would one go about debugging a custom robotics model, since the information inside isn't accesible. Is it possible to find the source of where the function breaks? Any hint in the right direction would be appreciated. Best regards

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.

I want to cancel the automatic address allocation for all IO mappings. If I directly set the automatic_iec_address in class ScriptIoMapping to False, the address becomes None. So I reset manual_iec_address with itselfs value. It only work with the Input IOMapping . For output, it reports an error: "Invalid address: The channel type 'Output' requires address type '%Q'." I checked the description file ,both accessRight are total same. Does anyone know what causes this?

Post by imdatatas on SMC_ERROR.SMC_AXIS_NOT_READY_FOR_MOTION when using Drive Virtual ^{CODESYS Forge talk (Post)}
@ducng, Another possible situation could be that normally there are 3 inputs for MC_Power. In your above images, I can't see the "bDriveStart" input activated. As Mr. @gseidel mentioned, you need to make sure MC_Power.Status output should be TRUE. Issuing any movement command without activating the axis would naturally result in an error. For MC_Power; You can set the Enable and bDriveStart inputs to TRUE and try turning the axis activation on and off using only the bRegulatorOn input. Regards, Imdat

CODESYS 64 3.5.19.70 runs after a lot of Package deinstallation/installation handling. But every think looks not really stable. Deinstallation of MS C++ and MS Runtime stuff -> CS installation. Than deinstallation of CodemMaster for anti freezing CS.
