Post by tvm on Timer On Vijeo ^{CODESYS Forge talk (Post)}
Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

yes sure. Thx for your support! This is the Codesys project stripped down only to my EtherCat and OneWire Configuration. The Project now contains only one OneWire Master on GPIO4.

Post by struccc on Wish: CODESYSControl.cfg - again ^{CODESYS Forge talk (Post)}
Before creating this topic, I was browsing the search results for CodesysControl.cfg - many results, and I remember very well, it's a problematic issue for a long time. To summarize: there were many requests for documentation on this file - the most comprehensive reply is: https://forge.codesys.com/forge/talk/Runtime/thread/ebbf851a3d/#eb85 Hi, not really, this is covered by the manual which you get if you use a runtime toolkit which is not free of charge. Maybe we need to extract the config file part from that documentation if that is possible. BR Edwin I am not sure how much is this relevant, since we buy SL License directly from CODESYS... I think it is a reasonable demand, to get documentation on the configuration entries affecting the documented behaviour of the runtime system and it's components The actual reason I bring up this issue again can be read here: https://forge.codesys.com/forge/talk/Runtime/thread/febad3cc40/#0e12 but mostly my frustration about noticing some new, unknown and undocumented entries in my configuration file. Again. And this happens a lot recently. Just some examples: Changes with SysFile - and mandatory use of IEC path Introduction of Mandatory user management File transfer service now disabled by default SysProcess - allowed commands The above mentioned CmpApp parameters... And finally (Regaridng windows install): With the newer versions, the installation directory (together with the configuration file) tends to hide itself to some super silly location under the roaming profile data of local system account. I am not sure if this change was documented somewhere, but was a very unpleasant one. Someone could please explain the reason and the concept of the introduction of this release specific directories (I am sure, there is a good reason) - how to use them properly? - How to re-introduce user configuration (to preserve configuration data between versions)? - How to do version - to version migrations properly? - How to keep old version of runtime available and ready to start with it's original configuration and application? - ... Therefore, the lack a regularly updated description of CodesysControl .cfg , including all the configuration entries, together with their default values for different runtime versions is really a big deficiency.* This should be done for all components storing or just seeking data from this file... (Maybe there is such thing but I failed to find???) It is regularly causing trouble when introducing a new version (together with the long awaited bug fixes and enhancements), what has changed it's default behaviour for security or other practical reasons. I agree this is very important, and it is logical to change the default options: But it must be documented historically, and make it easily available, so we can prepare better for the upgrade of the runtime. Forge talk is a great source, but not very practical for this kind of documentation purposes... Thanks in advance for CODESYS staff 🙏🙏🙏 (Ps.: It would look rather silly, if some members of the user community prepares this documentation on a Forge Wiki page... Or??? Should we?)

Post by forest on SM Drive license error ^{CODESYS Forge talk (Post)}
Hi, when it comes about license, I used INVTmatic Studio, which uses Codesys, for programming INVT plc. I bought Codesys Modbus license, it was not expensive, and then realised that INVT didn't have License Manager option (greyed out in program) which is needed for using of Codesys License. I contacted support from INVT, but developers told me that option is still not available. So depending on environment for programming Codesys, you can or not use Modbus license. Good thing about this version of Modbus TCP it works both direction. I could send commands and receive feedbacks from drive. But communication stops after 30 mins. So I used simple version of ethernet modbus which is somewhere in INVT or Condesys library (I can check tomorrow) which works only one way. I could send cmd to drive, and control it, but didn't have any feedback, like some readings back in PLC. which is bad, but at least I could start it and it didn't fail after 30 mins.

Post by trusty-squire on How to revert to previous version library ^{CODESYS Forge talk (Post)}
Hi, I'm experiencing a bug with the latest version of SoftMotion CNC library (4.17), where the 3DPath object in Visu is missing all the important properties. I've verified that a previous app I was working on with library version 4.16 did not have this issue and the issue is duplicated in that project when I update it to 4.17. I've already submitted a bug report, but for the time being I need to revert the project I'm currently working on back a revision. I've tried right clicking on the library but the option to select the version is greyed out. Can anyone help me?

Post by caliberbishop on Having trouble using the Web Client SL library ^{CODESYS Forge talk (Post)}
Hello, I'm trying to use the Web Client SL library, I installed it in the IDE (did not purchase a license yet, as this is still a proof of concept so demo mode is good enough) and added it to the library manager. However, when trying to define a FB of the type WebClient I get a "Identifier 'WebClient' not defined" error message, setting the type to Web_Client_SL.WebClient did not work as well. Opening the example project the FBs defined there give the same error message. From the problem in the example project I deduce this is not a syntax problem, so maybe a license problem, but there should be a working demo mode, so what am I missing? IDE v 3.5.21.30 Library v 1.12.0.0 Thanks

Post by alimans on OPC-UA Server, Symbol Set: Raise an error: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Hello If you uncheck 'Auto restart Communication', it will try once and never again. You can manually reset the slave if needed : Slave.xReset (or something similar) Or I have a ModbusRTU library if you want to try it.
