Post by davidmic on Is it possible to profile builds? ^{CODESYS Forge talk (Post)}
Hi I have a large project (which I can't share here), builds take multiple minutes. My computer is reasonably new (i7-10610U, 32gb ram), and I don't think my company will let me upgrade. Is there any way to profile/inspect the build process? My goal is to figure out why builds take so long, then hopefully I can make them faster.

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
It doesn't load differently codesys seems to be behaving differently. Original version of ethercat master in project archive is 3.5.15.50, compiler is 16.4 as is codesys I'm using. It builds fine in vm and not on local machine. The reason is not obvious. It builds on local machine with ethercat master at 3.5.16.0. I'd really appreciate advice

Post by gseidel on SMC_ERROR SMC_CGR_INVALID_POSPERIOD ^{CODESYS Forge talk (Post)}
Hi blitz, that usually means that the modulo period, when converted to increments, is larger than 2^31. (The bus bandwidth is usually 2^32.) What is your "technical unit", do you program in angular degrees? And what is the modulo period? If you want you can post the drive configuration (screen shot of the "General" and "Scaling/Mapping" page). Best regards, Georg

I was just wondering is the following option possible and what the settings should be. Is OPC communication possible with only and mandatory server certificate but no client certificate?

Post by installwhat on exception in system events handler ^{CODESYS Forge talk (Post)}
I've noticed that exceptions in system event handlers don't stop the runtime or call the exception handler. I've included a very basic example to demonstrate. It seems likely this is undesired but unavoidable. Is that the case? Is there any advice on the matter? Thanks

Post by xgongx on What is the insights of IoDrvEtherCAT.DCInSyncWindow? ^{CODESYS Forge talk (Post)}
It is well known that you need to increase the value of IoDrvEtherCAT.DCInSyncWindow to solve the "Fieldbus lost synchronicity" issue. In the official document, IoDrvEtherCAT.DCInSyncWindow is explained as the toleration of a certain jitter. But the official document doesn't explain what kind of the jitter is. Is it the jitter of DC sync deviation, master timer or something else? It is very important to know the insights of IoDrvEtherCAT.DCInSyncWindow. For example, if it is the toleration of DC sync deviation, and the official recommending value is 200us for CODESYS SoftMotion. It means maximum of DC sync deviation is 200us. It is unacceptable for some high precision motion control tasks, for example high speed gear task, etc. Increasing the value of IoDrvEtherCAT.DCInSyncWindow will increase the deviation of motor rotation sync if it is the toleration of DC sync deviation. So, would anyone tell me what the insights of IoDrvEtherCAT.DCInSyncWindow is? Thanks.

That is an output of the Function Block ModbusMasterRTU example: xIsConnected=> xIsConnected In this line the VAR ModbusMasterRTU.xIsConnected is written to VAR xIsConnected xError=> is writing to nothing here.

Hello, Is there a maximum number of Masters that can connect to a Modbus Slave that is configured in the device tree? Is this limited by the CODESYS IDE, or the manufactures hardware and CPU load? Thank you,

I've created a very basic version of this problem as a project. Please see attached. One of the libraries in conflict is different from that described above, but the problem is the same. My development environment is 32bit v3.5.16.70 using v3.5.11.0 compiler.

Hi, I have a Combivis studio 6 licence. What I need is information from Codesys about how the information 'Download time' is saved and if it is possible to modify it manually.

Post by tk096 on Sm3_math ^{CODESYS Forge talk (Post)}
Hi, SM3_Math is actually an internal library of SoftMotion. You can use it. The only restriction is that there is no compatibility guarantee - meaning that POUs in the library may change their interface, get moved/renamed/removed... in future versions of SoftMotion.

Post by timvh on library is not available ^{CODESYS Forge talk (Post)}
Which PLC do you use? If it is a standard CODESYS Runtime (from the store), then maybe update the device in your project to the latest version. If it is not a standard CODESYS Runtime, then maybe contact the supplier.

Hello, the request is no longer relevant. Thank you. Working with the Main Menu bar via the Alt key is the most effective method. It has absolutely everything there. Calling the context menu via the keyboard is not necessary.

Post by voffi on About Codesys Task Executions ^{CODESYS Forge talk (Post)}
A task in CODESYS normally is a task of the underlying operating system. If your os is preemptive and the sheduler is configured accordingly a CODESYS task will be preemptive too.

Post by matt-s on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
I know, that is not the issue though. The issue is the HMI_Blower_Auto_PB variable not changing to false. I do not have the IO modules plugged in yet, that is why there are NaN values for those variables. That should not affect this.
