Post by bmatlove on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
I'm trying to firm up alarming of axis faults. Declutter the code and figure out what's what. Diving into it, I see the AXIS_REF_SM3 function block provides uiDriveInterfaceError and dwErrorId, but I can't find any significance of these further than Drive interface error number Parameter number: 1014 and Drive specific error identifier, parameter number: 1031, respectively. Is there some corresponding appendix I could use to decode these? Also, is there any relation to the Error ID (of type SMC_Error) of the MC POUs? MC_Jog, MC_Reset, MC_MoveRelative, etc? If so, are the above errors redundant? Thanks in advance.

Post by nathant on Some visualization objects disappear when user is logged in? ^{CODESYS Forge talk (Post)}
I am deploying a webvisu on Codesys 3.5 SP 19.2 with legacy user management. I noticed that when a user logs in, some text and a rectangle I have (for aesthetics) both disappear. I made sure that none of the objects in question are linked to a state variable. Anyone know the cause/solution to this? Nothing crucial to the machine's function is lost, but it is a little annoying.

Post by svn123 on In Simulation Mode, logic is not executing ^{CODESYS Forge talk (Post)}
Please check the attached snapshot. I am converting an int to real and storing in rVlv01_SV and then scaling the value using LIN_TRAFO. In the bottom Status Bar of Codesys, both RUN and SIMULATION are visible. When I enter value 100 as input to INT_TO_REAL instruction and press Ctrl-F7, the value can be seen at the input but the logic seems not to work. I searched for help but could not find anything relevant. What could be the reason. Codesys ver3.5.11 svn

Hi Edwin, Thanks for the message. My apologies I should have researched this more thoroughly before posting on here. I found a solution to my issue on this post: https://forge.codesys.com/forge/talk/Runtime/thread/6455efaa17/ I needed to run the 'CODESYS Installer' as an Admin, then install the RPi package v4.10.0 in to my package (v3.5 SP19 Patch 5). Thanks, hope you have a good day. Toby

Post by rpostwvu on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~

Post by ofey on two different OPC clients with different privileges ^{CODESYS Forge talk (Post)}
Hi! I have usually only connected one OPC client (our system) to an OPC server created in the codesys environment on a PLC. This OPC client has a lot of write privileges. A customer also want OPC access, but I want to restrict his access to only read certain values. Do you know if this is possible inside the single codesys runtime running on a controller?

Post by jinlee on Multiple WebVisu ^{CODESYS Forge talk (Post)}
Hi, thank you for replying. Basically, I have a main visu with frame selection. So, under some condition the frame will switch to a specific frame. It used to be controlled by variable using "Switch frame variable". However, I realise it will change all the HMI screen at one time. So I removed the variable, and still looking for a solution to do that. Do you have any idea?

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 timvh on IFM CR711S Version Mismatch ^{CODESYS Forge talk (Post)}
You should ask IFM to provide you with the correct version of their controller packages. Then after you have installed this, you can select the correct version of the controller by right clicking on it in the device tree, update device, enable the option "Display all versions" and then select the version which matches your controller. Alternatively you can ask IFM to provide an update package which can update the runtime version on your controller to 3.2.0.0.

Hi everyone, Had that problem before where I could not create another user but used the method just above and it worked great. My problem now is that I get this message when attempting to logon to the device: invalid user authentication on the target dev5, the new user created is pretty much a copy of the user 'Owner' except for the password. Any idea as to why I am always getting this "invalid user authetication on the target" message ? Using Codesys V3.5 SP19 Patch 6 + (64 bit) Regards

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.

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 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

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
