Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
yes sure. Thx for your support! This is the Codesys project stripped down only to my EtherCat and OneWire Configuration. The Project now contains only one OneWire Master on GPIO4.

the project has only one OneWire Master - so if you add the setting "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ to the config file it will fail and the Ethercat task will be blocked by the OneWire Master readings?

Could you check the taskcycle time in the taskmonitor (online monitor) - do you really see this 1s on Ethercat Task? Need to check this on my hardware but will take some time...

Hi ducng, please make sure to call all Motion-FBs in the EtherCAT task. In your case, the PLC_PRG should be below the EtherCAT task, not the MainTask. Best regards, Georg

Hello everyone, I have a little problem with textfield display. When I put a solid backgroud, no problem. But when I put it to invisible, some strange things appears with the text. Do you have this kind of issues ? Thanks a lot, Tristan

Maybe check: - The library manager, are you maybe missing some libraries - Tools - CODESYS installer: update the CODESYS Visualization and Visualization support - Project - Project environment: maybe you need to update the visualization profile

I experienced the same problem: using __VARINFO is working only in PRG context, while it crashes if used inside Function Blocks. I would really appreciate if they would fix this issue

Hi George - ok thanks - but who created this FB in the first place? Could you lead me to the creator company? Is CODESYS not the old S3 that created this FB? :-)

you can try to disable "Visualization Manager - Settings - Support client animations and overlay of native elements " selection" It worked for me, thank you.

Post by blitz on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
So in my case the solution was that I had both smooth path and round path in the code. Both blocks had their own buffer and seemed completely separate but still triggering Execute on both caused the mentioned problems. When I blocked Execute the problems disappeared.

Under Application->"Task Configuration" you can find your task double click on that and you will see a fane to the right. You find the watchdog enable switch it off or increase the time

Post by tjacks on Opc UA Data Source Client Browse Error in Codesys HMI ^{CODESYS Forge talk (Post)}
Codesys V3.5 SP21 Patch 3 Codesys HMI 3.5.21.30 I'm trying to connect to an OPC UA server on a Kuka robot controller using Codesys HMI's data source manager. I get through the login phase and the client browses most of the data structure on the server but errors out toward the end with a generic: Error while browsing the client, Failed with service result: BadUnexpectedError. If I complete the data source setup and try to update variables, I get the attached stack trace for the error. I've tried several different endpoint and security options. Most get me through the login but all error out while browsing. UA Expert happily connects and browses with the same configuration. I've connected this same version of Codesys to TwinCAT OPC UA servers and Siemens PLC OPC UA servers. Any ideas on what may be causing the generic BadUnexpectedError during OPC UA server browse?

Post by jv-certhon on Io driver Scan functionality ^{CODESYS Forge talk (Post)}
Hello, Codesys IDE is 3.5.21.30 IoDrvBase is: 3.5.17.8 I am working on implementing Codesys on our I/O product line, using the IO driver examples, and the Linux UDS socket approach. I have sucessfully created an implemetation where I have a Device with mutiple slots, on which I can plug modules. These modules represent our IO modules, and communication is successful. (For this question the assumtion can be made that Codesys commucates with 1 'master' device, which handles further communcation with the IO modules. For the next part of the question it can be assumed that the Master device has a list of which modules are attached/available) I'm now trying to implement the 'Scan for Devices...' feature, but I'm completetly lost on what to do once the IoDrvScanModules method is called in my IoDrvFB. I'm guessing that the ppConnectorList has to be filled with the found devices, but I have no idea if that is the correct approach. And Codesys is not triggering my breakpoints in the method, which makes things more difficult. I hope someone could provide some examples or guidance on what steps I should take to implement the scan feature. Thanks in advance.

Is it possible to do non-formal invocation of function blocks in CODESYS? I get an error when I try, see the attached pic. Also attached a pic from IEC 61131-3 describing non-formal invocations.

No that is not possible for function blocks, although it is possible to that with methods and functions as you see in your second pic.

You need proper scaling from raw ADC counts to engineering units, handling underflow, overflow, and using linear conversion logic carefully.

Post by spiessli on Raspberry Pi 4 with Legacy Drivers and Codesys 3.5.19 Patch 4 ^{CODESYS Forge talk (Post)}
Hi, I wanted to use the Adafruit Hat for the Raspberry and get acquainted with Softmotion using servos for RC models. This did work great with Codesys 3.5.19 Patch 1, but with Patch 4 and 5 i get errors. I suspect changes in the SoftMotion library have broken dependencies in the legacy drivers, might that be true?
