Post by antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers ^{CODESYS Forge talk (Post)}
Looking for thoughts on creating libraries that can be used on both 32-bit and 64-bit controllers. We are currently writing software in CoDeSys for both target types and will continu to do so for the near future. Projects are always unique, no straight forward copy/paste, yet there is enough similarity between them to use libraries for recurring logic. I do not want to create and maintain twice for both platforms if this is not absolutely necessary. I am aware of useful datatypes like __XWORD, __XINT, __UXINT. Still looking for more information and/or sample code for portable pointer arithmetic. In addition to that: how should one go about when creating and working with compiled libraries? Would I need to compile the same lib twice, once for 32-bit targets once for 64-bit targets? I would end up with two different libs with the same namespace, which does not sound elegant to me. Note: I did not intentionally make the previous paragraph bold. The forge forum software seems to do this automatically upon insertion of a word which starts with two underscores, e.g. __XWORD (yeah, here we go again :) )

Thank you, so "Remote TargetVisu" is the same thing as "TargetVisu"? I think there needs to be more documentation about this, its very confusing.

The fix for this is when you install the control SL license, there is a checkbox for the Visu S license option. You must click this option. The Visu M is technically an upgrade to the Visu S, if this is license is not installed them the Visu M will fail as shown above. Thanks JoJo for the solution!

I got this code working again. 3S/CoDeSys, your level of obfuscation and lack of documentation turns a simple task into a monumental complex challenge. The issue was that at some point the IecVarAccessLibrary changed and no longer allowed using IBaseTreeNode to retrieve a child or the number of children. The attached code has been updated to use IIecVarAccess6.VarAccBrowseGetChildByIndex instead. The code was also cleaned up but is still a work in progress. The current example only works one layer deep. This means native data types, arrays, and single-layer structures are supported. However, structure arrays and nested structures are not yet supported.

Post by kporter on High-resolution drive with SoftMotion ^{CODESYS Forge talk (Post)}
I'm beta-testing a new EtherCAT drive for a rotary (modulo) axis in a system where the encoder resolution is 81920000 counts per rotation. If I enter this in the SoftMotion Scaling/Mapping tab for "increments <=> motor turns", I get the error below on the Commissioning tab. Is SM unable to handle a high-resolution encoder? The bus cycle is currently set to the default of 4 msec (Control Win V3 x64), although I plan to reduce that to reduce latency, possibly by switching to the realtime (RT) master. Is SoftMotion incompatible with high-resolution encoders? SMC_CGR_INVALID_POSPERIOD Invalid modulo period (<= 0 or greater than half the bus bandwidth)

Maybe your slave device didn't properly closed its socket port and CODESYS is unable to reconnect? Did you restart your slave device?

I'm not sure, but maybe you need to install or update the "CODESYS Communication" add-on through the CODESYS Installer.

You don't have to create 2 libraries. CODESYS will handle it automatically based on the selected device in your application.

Post by imdatatas on C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr ^{CODESYS Forge talk (Post)}
Hello everyone, I downloaded the "Example: PLC Chat Net Base Services" example from the Codesys help site to review and try it out. https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_cds_plc_chat_net_base_services.html However, when I open and compile the example program with SP21 Patch2, I get the strange error message below regarding Visualisation component, and it fails to compile. " [ERROR] visuelems, 4.8.0.0 (system): VisuFbTabControl: C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr " Are others experiencing the error "C0138: No matching 'FB_Init' method found for instantiation..." when trying to compile example projects created with older versions of Codesys with a later version of the IDE? How did you overcome this problem? Could you share your solutions? Regards, Imdat

Which device do you use? Does this have persistent memory (e.g. NVRAM) available? Maybe first ask your PLC vendor about the possibilities and how they advice to use persistent variables? If you have no NVRAM available, CODESYS will store the variables in a file when the device gracefully shuts down. But on an abrupt power failure, this is not possible. If you have no NVRAM and you want to use persistent variables, then consider using a UPS. In this case when the power is lost, the UPS can keep the power on the PLC which then can gracefully shut down. Alternatively use the Persistence Manager to store the variable values in a file e.g. only on change. See: https://content.helpme-codesys.com/en/CODESYS%20Application%20Composer/ac_pm_overview.html

Change the actual time of your PLC. How to do this sometimes depends on the PLC you use. Please contact the vendor of the PLC to get this information. Or see the following example for using CODESYS date and time functions: https://forge.codesys.com/prj/codesys-example/date-and-time/home/Home/

Hello, I have a Raspberry Pi 3 which has a printer connected to his USB port. I have a PiFace Board on the Raspberry. I have a python script file (.py) to print a logo + a text. The script is working because when I execute it from the Raspberry terminal it works. Now, when I push a button on the PiFace I would like to execute the python script file to print. How can I do that ? Many thanks for your help and advices!
