WAGO will use 0-32767 as the raw units. Note a value of 3 means over/under range. Map that IO however you please, then scale in your program using any of the available libraries or with your own simple y=mx+b scaling formula to get to the engineering units you desire. Inverse for the AO to get back to 0-32767.

Post by timvh on Colors look different when logged in and running ^{CODESYS Forge talk (Post)}
At the top of the Visualisation Properties View, you can enable the "Advanced" options. This will give you access to more properties than what you currently see. There might be a variable linked to the "advanced" colour property where the fill colour is determined by the value of this variable (dword).

Post by ekristoffe on Modbus UDP ^{CODESYS Forge talk (Post)}
UDP has no packet ordering mechanism, and Modbus protocol has no order checking mechanism nor session establishment. I'm sorry but this is false, Modbus IP based have the Transaction Identifier. Transaction Identifier - It is used for transaction pairing, the MODBUS server copies in the response the transaction identifier of the request. Modbus UDP make more sense than Modbus TCP in a local environment.

Thank you, Bingo. I have added the instructions below to the CODESYSControl.cfg file, but they haven't changed anything. [SysSocket] Adapter.0.Name="ETH0" Adapter.0.EnableSetIpAndMask=1 Adapter.1.Name="ETH1" Adapter.1.EnableSetIpAndMask=1 Regarding your second suggestion, could you please expand a bit on that?

Post by domebruce on Which database to use? ^{CODESYS Forge talk (Post)}
We have developed a similar application few years ago with .Net and MS Sql Server. The database has about 30 tables, the more bigger tables have 2 or 3 thousands records. We can have multiple threads accessing at the same time to the DB. To garantie the data integrity we need to manage data locks and transactions. Thanks

Post by tvm on VisuFbFrameBase.SetInputPositionData: The element id for the input position cannot be determined ^{CODESYS Forge talk (Post)}
This came up again today, so I'll post the fix for future reference. Happens with Schneider Machine Expert 2.2 and M262 controllers. Add this bit of code to a program called from the visu task //disable "VisuFbFrameBase.SetInputPositionData" log messages, which fill up the logs IF VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.GetListenerCount() > 0 THEN VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.RemoveValueChangedListener(VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.listenerForOnValueChanged); END_IF

Post by fmon on Modbus TCP client reconnection problem ^{CODESYS Forge talk (Post)}
Problem solved The client modbus cycle time was linked to a task at 500ms. Whereas the channel modbus was at 200ms. Certainly problem of packages synchronisation. I let the client modbus cycle time to be handled by itself (See attachement) --> "Use the bus cyle time parameters" (traduce from french) See attachement

1) In the library manager of your project select "Download missing libraries". 2) In the library manager open the "Placeholders" dialog. In here find the Placeholder which is not referenced to a specific library yet. Click in this line on the Library column and select the latest version of this library.

Hello everyone. I am using Codesys and saw in a YouTube video on the Codesys channel (https://www.youtube.com/watch?v=y_l2siXY7dA) that you can create frames and move them with the mouse. However, the video does not show how to do this. Can someone please explain it to me? Thank you very much.

Hi! I am trying to achieve the same issue. Has there been a solution? I can create the mapping, and map the local variable, but somehow the object does not update. Furthermore, i have an issue where codesys doesn't let me set ReadWrite accesses to the variables in the "Type Mapping" place. The access will simply not be set. Has anyone ran int that issue?

Hello Everyone, Create separate repositories option not working in latest Codesys Installer 2.4.0 (Build 3545). It seems like a useful option regarding install the different versions of Codesys IDE on the same computer and keep in isolation from each other, but unfortunately it didn't work. I hope the Codesys team can fix this issue in the next update. Regards, Imdat

Post by snguyen on Atomic and Shared memory? ^{CODESYS Forge talk (Post)}
Hi, I've read that you can perform Atomic instructions like AtomicReadLInt on variables. However, I'd like to know if this uses stdatomic internally. My main question is : Is it possible to share atomic types in shared memory with CodeSys. If so, what types should they be declared as? If not, are the atomic functions lock-free or does it use a mutex?

Hello, many thanks for your reply. I checked the logs. It seems that dll is not loaded. However other dll such as the Webserver are loaded. Could you tell me what I need to do such that my dll is loaded. (Furthermore I changed the C-Function a bit. I used the M4.exe from the SDK.) Many thanks.
