I also would like to now how to clear the PLC Device Log. @eschwellinger are you saying there is no way to clear the log? When I am debugging I want to clear the log, it would make things some much easier to find.

You have to update the device in your IDE to 3.5.14 or you can contact your Codesys runtime supplier to know how to set the connected system to 3.5.19

I have to enter the owner password from time to time, even though I haven't closed the project yet. Is there a way to disable this option? So I only have to enter it once when I log in to the project, and that's it.

Solved it! The simple answer was to declare a variable as POINTER TO STRING and assign the GetMessage result to that variable. Then, the ^ operator can be used to extract the message as string.

Hi, I would like to divide a project into multiple applications - as a minimum: one handling visualization and Alarm Manager, one handling I/O and plant control logic. But how to exchange variables between the applications? What have you done to get such a solution? In versions 3.5.19 and earlier, you can have Child applications, where the children can access a GVL in the Parent application. Children apps is no longer possible in 3.5.20 - but you can have 'sibling' apps - Several apps directly under PLC Logic, that is. But how do they best communicate? The Communication Manager / Data Sources Manager is sort of possible via OPC UA, but it seems like overkill and with some limitations - for example no ARRAY OF STRUCT possible this way. If you have separate devices in your project, you can exchange data via 'CODESYS ApplicationV3', but not other applications in the same device (see attachment Datasources.png). You can do it via 'Select the project type'->'Other Project' and select the same project file, but this leads to crashing the Development system when working with the variables afterwards. It would be great to hear your thoughts / experiences on this topic - Bjarne

When you use a string value 0 will be the end terminator. Everything after this will not be in the string. I guess byte 2394 has a value 0.

Post by mrkm-dic on CODESYS: Combining Master Redundancy with EtherCAT Ring Topology – Is it Supported?
CODESYS Forge
talk
(Post)
Hello, I would like to ask whether it is technically supported (and practically achievable) to combine CODESYS Master Redundancy with EtherCAT ring (loop) redundancy in the same system. System setup CODESYS version: CODESYS 3.5.21.40 CODESYS Control SL for Weidmuller u-OS-4.12.2.0 Controllers (Masters): Weidmuller UC20-M4000 ×2, configured as Active / Standby using CODESYS redundancy EtherCAT Slaves: Weidmuller UR20-FBC-EC ×3, supporting EtherCAT ring / line break detection Topology: EtherCAT ring (loop) Main question Is it officially supported to use: ・CODESYS PLC/Master redundancy (Active/Standby) and ・EtherCAT ring topology (for cable redundancy) at the same time? Expected behavior Our expectation is: ・When the Active PLC fails, the Standby PLC becomes Active ・The Standby PLC then takes over the role of EtherCAT Master ・EtherCAT communication is re-established ・I/O control continues after reinitialization (a short interruption is acceptable; no strict bumpless requirement) We do not expect completely seamless / zero-cycle switchover, but we want to understand: ・Whether this combination is supported by design ・Or whether there are known limitations or restrictions when EtherCAT ring mode is used together with Master redundancy Clarification At this stage, the question is mainly about feasibility and support, not about a specific error message yet. Any official guidance, limitations, or real-world experience would be greatly appreciated. Thank you in advance.

Thank you for your interest. Your answers are in line with what I knew, so at least it comforts me that I did not misinterpret the situation. However, I don't have an exact match as, for this project over the past few days I have: 1) I have gone back to leaving the various FBs of the motion always called, all of them, and in the state machine I use a boolean to activate the various useful Execute. (But in the future I want to go back and try the programming technique with which I wanted to develop this project); 2) For the occasional error: SMC_FB_WASNT_CALLED_DURING_MOTION perhaps it was due to the fact that I had set the Ethercat bus synchronism only at the CAN master level, but not at the level of individual drives. I have now also activated it for the individual drives and it does indeed seem to have been resolved, but having also adopted the programming technique mentioned in point 1), I cannot say whether this was the solution to the problem, or instead the previous point. Is there an error ‘regulator or start not set’ in the device log before the error ‘motion generating FB wasn't called for at least one cycle’? I can't answer that right now. By now the machine is running and I am no longer there, at this one. Also, I seem to remember that the 'fbeFBerror' drive structure (5-element array), does not cycle, BUT ONCE THE 5 EVENTS AFTER SWITCHING ON, IT DOES NOT UPDATE ANYMORE (but that's another issue), so diagnostics were not easy.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
