Reset / Set an XVE module ctrlX XVE into operational state via a ctrlX PLC command.

Hasan-63 — Thu, 02 Apr 2026 08:22:02 GMT

Hello,

I have an XVE module (R914511578) communicating with my ctrlX CORE X5 PLC via EtherCAT. Each time the system starts up, or whenever the XVE module changes state and returns to OP mode, I get the following fault.

To acknowledge it, I currently use the "Clear Error" function in ctrlX Drive.

I would like to know how I can send a command from my PLC to reset this error.

Slow Git operations in ctrlX PLC

Klimenta-66 — Mon, 30 Mar 2026 13:26:38 GMT

Hello everyone,

we have been experiencing consistently slow performance when using Git within the ctrlX PLC since we started working with it.

Almost all Git operations are affected, for example:

switching branches
pulling changes
general Git functionality

The delays are noticeable and occur consistently, not just occasionally.

We would like to ask:

Is this a known issue in the ctrlX environment?
Are there any recommended solutions or best practices to improve performance?
Could this be related to network factors such as firewall restrictions, proxy usage, SSL inspection, or something else?

Any help or guidance would be greatly appreciated.

Best regards

Symbol setting representation

macken88 — Mon, 30 Mar 2026 09:44:02 GMT

We have a project where we need to read enumerations as basetype in the HMI and have set up the PLC accordingly
We have noticed though that sometimes after a warm reset or plc exception these settings are reset to flatbuffer again. Is there any way to make this setting more consistent so it holds the value even if the plc application would crash?

FlatBuffers. Create Tooling Data Sets from PLC

Usalas-58 — Tue, 24 Mar 2026 21:52:26 GMT

I ran into an issue when creating Tooling set using PLC FlatBuffers.

From Datalayer works fine, and I think that the toolDataEdgeOri is asking for a String. but the PLC method asks for an enumeration which return an Integer. Not sure if that is the issue

attached is an export of my code.

ctrlX PLC Engineering Fails to Launch in the CtrlX project

Bhuvana — Tue, 24 Mar 2026 05:25:33 GMT

The PLC Engineering application (plcengineering.exe) is not launching on my system. When attempting to open it, I receive the following error message:
"A new guard page for the stack cannot be created."
I already tried C:\ProgramData\ctrlX PLC Engineering\Options renaming and removing LiveOptions which was suggested in some post. this also did not work.

Pending Diagnostic - error message

redford — Tue, 17 Mar 2026 09:09:36 GMT

With GetPendingDiagnostics, you can read out the diagnostics of the Core. However, the string only shows me the instance of the triggering error, which is not very interesting for maintenance.

Do I have a way to get to the text of the error message (here: "TargetPos max Limit exceeded")?

For the drives, this is not a problem via S-0-0095. Like the solution that we have using A-/C-Parameter with XM platform.

CtrlX PLC Engineering freezing by adding blocks to CFC logic

Christian-91 — Thu, 05 Mar 2026 11:14:15 GMT

We facing the issue that the CtrlX PLC Engineering (v3.6.3) is freezing or stucked for minutes if we just add a empty box to an excisting CFC Chart. Even if is getting unfreezed after several minutes it will freeze again and again for minutes if we change any thing on the CFC Chart. The Same behavior happens on difference Computers. The PLC engineering is no connected to X3 / X5 IPC.

Is there any know issue with PLC Engineering and CFC and is there any workaround?

Best regards Christian

Write Data Layer node class Method with PLC

Olivier_Graille — Wed, 04 Mar 2026 14:21:47 GMT

Hi Community,

Can a Method node be written into the Data Layer using the PLC app ?

I try to use the CXA_Datalayer Library on the PLC but I can only write node with bool or interger type.

(I don't want to use Node-Red)

Regards.

TrendStorageAPI

Bereke — Fri, 27 Feb 2026 12:53:25 GMT

Hello everyone,
In the project I am currently working on, the client requires the trend recording data to be exported in CSV format. By default, the ctrlX PLC stores this data in an SQLite database.I recently discovered that there is an API available that allows access to the TrendRecording SQLite ( CODESYS Forge - Trend API Example / Home / Home) database and supports exporting the data to CSV format. However, I am currently facing some challenges while implementing this approach.
My trend recording has stopped working, and the timestamps shown below are incorrect.

and on this part of the code:

this values appear:

eError := instTrendStorageReader.GetMinMaxTimestamps(
liMinTimestamp => liMinTimestamp, // = 1388534400000000
liMaxTimestamp => liMaxTimestamp // = 1388534520000000 );

And the eError is equal to 30435

Motion app causing PLC exception with EtherCAT FBs

Jamie-61 — Thu, 26 Feb 2026 22:02:44 GMT

I'm hoping someone can help me understand why the attached POU causes a PLC Exception if the motion app is in "config" mode, but runs fine if the motion app is in "running" mode. It is using function blocks from the CXA_EthercatMaster library. I wouldn't think the motion app could effect the PLC in such a way. The attachment is a PLCOpen xml. I am using PLC Engineering 4.4.0
