Hi, Mine is the same, both using v3.5 SP17 patch 6, and v3.5 SP19 patch 5 when using anything newer than v4.8.0 the same issue as above occurs. Checked the 'Customize' window in case it was hidden/disabled in there but couldn't find it. Thanks for the help on this. Toby

Post by hagroth on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Today I was struggling with the same problem. in search for a solution i found this thread. Then i tried some things. It doesn't seem to be just a libraries' fault. In addition to 3.5.19, we also have a 3.5.18 version installed, the library versions of Modbus_TCP_Master and Modbus_TCP_Slave are the same, but more than 10 slave channels can be added in 3.5.18

to modify and change the color of this icons from symbols lib I placed it in a visu. After download to the device, I uploaded the SVG files and saved it local. Now I was able to modify them with inkscape and import it to my own imagepool in the project :-)

I'll have a look at this, thanks. Do you maybe know why the C-integration doesn't work? I'm just curious because it was still some effort to create all these files. Ending up with a meaningless error feels very unsatisfying to me...

Post by jaspergain on SoftMotion Axes issue ^{CODESYS Forge talk (Post)}
Dear, We have an issue with SoftMotion and it's licensing. We don't use SoftMotion in this project. But a SoftMotion license is required by it. The License metrics tell's us there is a -1 Axes. Is there a way to reset this? Delete this? There was a MotionControl device in the project, but we have deleted this. But it stayed at -1. Thanks for you help.

That definitely does the job with the Ladder Logic Diagram type; fully equipped toolbox. Just starting with Codesys and was following programming steps which explains the choice of ladder I had picked. Thanks for the tip and have a good one! Cheers!

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
I also thought that if I had logic writing a value to this variable, then it would override the force anyway, since I thought that the force request was only applied at the beginning and end of the PLC scan. But this doesn't seem to be the case, the force persists throughout the logic regardless of what I write to the variable with logic

Post by mp9876 on Device logon problem following fresh install ^{CODESYS Forge talk (Post)}
All screenshots are enclosed in MS Word document. NOTE; 4 questions features at the end. Any assistance would be greatly appreciated! Hi everyone, I am still having device logon problem following a fresh install Here are the STEPS I went through following a FRESH CODESYS Win 64 3.5.19.60 install on a different computer. ‘Gateway not configured properly’ when attempting to REFRESH from the Users and Groups. Then did Gateway manage and confirmed it was ok: This message popped out as it was a fresh install: YES then: Initially went with Administrator twice (user & password) but it did not like it. No device is responding to …: Continued by setting a new user Pressed OK and obtained the following message: Stopped and Restarted PLC at that point: Obtained the following: Attempted to login a 2nd time without success. Then I scanned the network to see if matching device can be detected: Only way to get it detected was to remove the tick in the ‘Hide non-matching devices…’ Attempted a WINK but got a return like this one: REFRESH either @ Users and Groups or @ Access Rights returns: Then created user ‘mp’ at Project level ang logged in: Understandably device user mp9876 was not valid for the Project. Device information A few questions comes to my mind following these connection attempts: 1- Gateway not configured properly message pops out because of a non-compatible device ? 2- Why would the device not be compatible ? 3- Any way to make the device compatible ? 4- Any ideas on how to get this connectivity problem to the device solved ?

Post by thewizard8 on Raspberry PI4 Serial Port ^{CODESYS Forge talk (Post)}
Hi All, I finally figured out how to solve it. The only away that I got it to work was to define parity to None on modbus configuration, and now works like a charm. Just for the record I'm using the GPIO port pins (8,10) and a RS485 to ttl shield that you can find online. Thanks all for the support! Regards Ricardo

Post by felipemsgarcia on Generic EtherCAT slave ^{CODESYS Forge talk (Post)}
Hello Edwin, Thank you foryour answer but, I believe I was not very clear in my question, sorry. What I wanted to know is if there is a generic EtherCAT slave object already in CODESYS that I can use for anything, remote IO, Drives, VFD's and so on, as long as I match PDO's. Is there such an object? Thank you again!

Hello, I'm experimenting with two applications. I was able to start stop applications with the CmpApp library. Currently in my test the variables declared in the first application are not visible and writable in the second. I ask if there is the possibility of having variables that are visible both in the first application and in the second.

Post by jeffersonhui on SysProcessExecuteCommand2 terminate ^{CODESYS Forge talk (Post)}
Hi, I am using the SysProcessExecuteCommand2 function from the SysProcess library to run the candump command in the PLC's Linux environment. However, the candump command stays running indefinitely. If I was running the candump command from a terminal (via PuTTy, etc), that command usually requires Ctrl+C to terminate. Is there a way to terminate a command that is executed with SysProcessExecuteCommand2?

Post by janber0206 on Gateway doesn't come online, regarding a working internet connection ^{CODESYS Forge talk (Post)}
Solved EN: The Problem is that the Codesys Edge-Gateways have a License with a runtime of an half year, as long the Gateways are online they will self renew themselfs. In my Case the RevPi was more than a year offline and so the Edge-Gateway was not working anymore. The solution: I accessed a laptop that was directly connected to the RevPi. I installed the Codesys service tool and renewed the certificate manual. DE: Das Propblem ist das die Codesys Edge-Gatways eine Lizenz haben die nur ein halbes Jahr gültig ist. Solange das Gateway eine Internet verbindung hat aktualisiert sich das Zertifikat von alleine. In meinem Fall war das Gateway aber über ein Jahr offline und hat somit nicht mehr funktioniert. Die Lösung: Ich hab auf einen Laptop von Kunden mit TeamViewer zugegriffen, der Laptop wurde mit Kabel direkt mit RevPi verbunden. Codesys Service Tool installiert und dann das Gatewayzertifikat aktualisiert.

Post by c3po on Von SNMP auf IIoT wechseln ^{CODESYS Forge talk (Post)}
Hallo, 1. ich bin komplett NEU was Codesys angeht 2. ich muss direkt ein Retrofit machen von V2 auf V3 3. Neue Steuerung: WAGO 750-8211 PFC200. 4. das Projekt in V2 hat über SNMP daten im Netzwerk zur Verfügung gestellt, oder diese gelesen 5. das Projekt in V3 kann SNMP nur noch eingeschränkt nutzen, deswegen wurde mir vom WAGO Support nahegelegt die IIoT Lib zu verwenden. Frage: Wie mach ich das? Konkret: Ich habe die WagoAppSNMP Bibliothek installiert, damit kann ich schon mal Set und Get nutzen (hoffentlich, hab es ja noch nicht getestet, sondern nur programmiert). Ist das ein schlauer Weg, das über diese Lib zu machen? Denn: was macht der SNMP_SET_PLCDATA_WRITEAREA ? Den kann ich über die Wago Lib nicht nutzen und weiß auch nicht, was dieser Baustein konkret tut (Bild im Anhang). Es scheint mir, hier werden Daten auf ein Word im Netzwerk geschrieben? Aber geht das nicht auch einfacher? Es ist ja keine Adresse hinterlegt, wo das hin gehen soll oder? Also, ich verstehe den Baustein nicht so ganz und konnte bisher auch keine Erklärung dazu finden. Vielen Dank schon mal für eure Unterstützung, K.

Post by gmau on RS232 Communication in CODESYS Control RTE V3 ^{CODESYS Forge talk (Post)}
Hello, I would like to implement RS232 communication into CODESYS Control RTE V3. I was writing the program testing it on CODESYS Control Win V3, where it worked fine. When I changed it to RTE, the communication was on, but I cannot send the data between PLC and scale - there is no or little response from scale - mostly one time receive and that is it. On Win V3 it was working fine. I read that I am supposed to configure CODESYSControl file for a proper communication using RTE, but even after that I can not get a stable and working communication. I am attaching my CODESYSControl and CODESYSControlUser data below, as well as I am sending the code from communication function. The communication should be through COM1 port of PC. CODESYS Version: CODESYS V3.5 SP21 + (64-bit) Runtime + Version: CODESYS Control RTE V3 Version 3.5.21.0 / CODESYS Gateway V3 - x64 Version 2.5.21.0 I would be much gratefull for any help. Sincerely,

Post by imdatatas on MC_MoveAbsolute: C0138: No matching 'FB_Init' method found for instantiation of SMC_MoveAbsRelPerformerImpl [ERROR] ^{CODESYS Forge talk (Post)}
Dear @gseidel, Thank you for your reply. The exact version of Codesys and its compiler was 3.5.21.20. The compiler version was fixed and could not be changed in project settings. Since I couldn't continue due to this compilation error, I temporarily overcame this issue as follows. -- I completely uninstalled Codesys 3.5.21.20 and completely deleted the Codesys folder in the C:\ProgramData folder. -- I restarted my computer and installed Codesys 3.5.19.70. -- I updated the Codesys Installer and all its add-ons to the latest versions. -- The project that was giving me the compilation error I mentioned before is now open with Codesys 3.5.19.70, compiled it, and successfully downloaded it on the device. -- I haven't encountered the same problem anymore. I think this issue is related to SP21 and its compiler. Frankly, I'd expect a project created with an older version to compile without errors after opening it with the latest Codesys version and updating all libraries. Regards, imdatatas
