Post by jasperclauwaert on Persistent Retain Variables Not Visible in Online View (WAGO PFC100 + CODESYS) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m working on a WAGO PFC100 with CODESYS. During development everything worked fine, but in the final stage I set several variables to PERSISTENT RETAIN. When I go online, most of these persistent variables cannot be monitored. Instead, I see: <Value of the expression cannot be retrieved> Interestingly, a few variables do show their values correctly, but the majority do not. The variables are not used as pointers or in any unusual way. The application compiles and runs without errors. Has anyone experienced this before? Is this a known issue with PFC100 or CODESYS? Any ideas on what could cause this behavior? Thanks in advance! Jasper

..the missing part is which Softmotion version is installed. Check it in the CODESYS Installer and update it to latest version.

Post by pernockham on Unable to deploy "Control for Linux SL 4.18.0.0" ^{CODESYS Forge talk (Post)}
The option to update "Control for Linux SL" is not shown in the "deploy control SL tool", I can see and update the gateway but not the control (3.5.21 SP4). Has the way to update control SL changed? In the process of fault finding I removed the control SL entirely from my target, then I had to revert to version 3.5.21.0 SP 1 to re-install "Control SL 4.17.0.0". So I thought it was just a matter of using SP1 to update also to 4.18.0.0, but after installing the files for 4.18.0.0 in the SP1-version, the behavior was identical to SP4, ie no Control for Linux SL shown in the deploy tool.. See screenshots.

Post by mascara on JOG continues in WCS ( SMC_GroupJog2 ) ^{CODESYS Forge talk (Post)}
I'm using the SMC_GroupJog2 block from the SM3_Robotics library for manual movement of an AxisGroup in WCS coordinates. The observed behavior is: When pressing X+, the X-axis starts moving correctly. If I press Y+ during the movement, the block interrupts the current movement and starts a new movement in X and Y. If I release any button, all axes stop, even if another button is still pressed. Example: Pressing X+ → X moves Pressing X+ and Y+ → X stops momentarily and starts XY movement Releasing X+ while holding Y+ → all axes stop The expected behavior would be: to allow simultaneous continuous movement on multiple axes to not interrupt movement when another axis is added or removed. Is there a correct configuration of SMC_GroupJog2 to achieve this behavior, or is there another block more suitable for continuous manual jog in AxisGroup (WCS)?

Post by egau on Importing a library overrides parameters of a referenced library ^{CODESYS Forge talk (Post)}
Hi, In my CODESYS project (ABC.project), I’m using the MQTT library. I’ve also created a separate library (DEF.library) which itself references the MQTT library. In ABC.project, I’ve customized some MQTT parameters—for example, setting g_udiMaxPublishersAndSubscribers to 100 instead of the default value of 20. However, when I import DEF.library into ABC.project, the MQTT parameters get reset to their default values. I assume this happens because DEF.library still uses the default MQTT configuration, which then overrides my project settings. A straightforward workaround would be to manually align the parameter values in DEF.library, but that doesn’t feel like the right approach. Is there a better or recommended way to handle this situation? I'm using SP18 Patch3. Any insights would be greatly appreciated. Thanks in advance!

these credentials are saved in the plc - you need to ask Festo how to do this.

Post by mattkaree on Mapping values with etherCAT mailbox communication ^{CODESYS Forge talk (Post)}
I am using a WAGO PFC200 PLC as an etherCAT master and a Keyence IV3-G120 with DL-EC1A attached as an etherCAT slave. I am using CODESYS V3.5 SP21 Patch 3. I was able to set up mailbox communication and can see values changing accordingly, but I want to know how I can map these values and reference them in my program. I am able to map the process data objects in the 'EtherCAT I/O Mapping' tab, but there is no where to map the mailbox values in the 'CoE Online' tab. Is there a way I can reference one of these values in my code?
