Post by abrarsk on SysCom Library Usage ^{CODESYS Forge talk (Post)}
Hello all, I am facing issues with using SysCom library. With SysCom23 library things were simple but since we are migrating to 64bit systems, I am writing a Porting program. With SysCom23, opening the comport was as simple as providing the ComPort no. which returns the Handle as a DWORD. dwHandle:=SysComOpen(Port); But the new library is a bit different. It is asking for 2 input parameters to open the Com Port - Port Number and POINTER to RTS_IEC_RESULT IF hCom = 0 THEN hCom := SysComOpen(ComSettings.sPort, ADR(pResult)); How should I use the RTS_IEC_Result? I can find RTS_IEC-REUSLT under SysType2Interfaces of SysCom library. Also, can someone give me a general understanding of this RTS_IEC_REULT and RTS_IEC_HANDLE, etc.?

Post by bernhardw on Probleme mit MC_HALT_SML und MC_STOP_SML ^{CODESYS Forge talk (Post)}
Hallo … ich verwende: SoftMotionLight im Positions-Mode Ethercat-Bus Servoverstärker: Metronix BL4104-C . MC_HALT_SML funktioniert nicht zuverlässig (Achse fährt manchmal zu weit oder bis zum Softwareschalter) Ich habe festgestellt, dass intern beim Aufruf von Positions- auf Velocity-Mode umgeschaltet wird - und dann wird wahrscheinlich intern auf Drehzahl 0 abgeregelt. Kennt jemand dieses Problem? – der Wechsel der Betriebsart ja ist nicht verzögerungsfrei! MC_STOP_SML Der Baustein hat keinen Eingangsparameter "Deceleration" Die Achse stoppt und bleibt im Positions-Mode. Aber die Verzögerung ist nicht wie beschrieben: nicht "Objekt 6085h: quick_stop_deceleration" - sondern "Objekt 6084h: profile_deceleration" - aus zuvor aufgerufenem MC_MOVE_ABSOLUTE_SML Ich wäre dankbar für jeden Hinweis Gruß Bernhard

Post by eguerra on Error in ScriptingEngine Docs - create_pou() ^{CODESYS Forge talk (Post)}
In the ScriptingEngine documentation there seems to be an error (or missing information) in the ScriptIecLanguageObjectContainer part ( https://content.helpme-codesys.com/en/ScriptingEngine/ScriptIecLanguageObjectContainer.html#ScriptIecLanguageObjectContainer.ScriptIecLanguageObjectContainer ). The description of the function create_pou() doesn't specify the correct arguments requested, it only says create_pou(type: SpecialPouType) and a script using the documentation definition of the function will raise an error. I tried passing the function arguments similar to the ones specified for the create_dut() function and it seems to work fine: create_pou(name, PouType) , name : str UPDATE: The offline help has the correct definition IExtendedObject<IScriptObject> create_pou( string name, PouType type = PouType.FunctionBlock, Nullable<Guid> language = null, string return_type = null, string base_type = null, string interfaces = null )

Post by sangeetnenwani on Test Driver Availability in CODESYS 64-bit and Test Manager 5.1.0.0 ^{CODESYS Forge talk (Post)}
I’m operating with CODESYS in a 64-bit configuration and the Test Manager at version 5.1.0.0, where I’m attempting to use project scripts from an earlier version. These scripts call for certain test drivers that are not present in my installation. It’s unclear whether the absence is due to the 64-bit system, an update in the test drivers, or if I need to enable or install additional elements. For instance, the loadproject(Codesys.Base) command is missing, but loadproject(testmanager.project) is available. The FileIO command for CODESYS isn’t accessible, yet the testmanager’s driver for it exists, as does the execuptscript command.

@gepert, When you say "I do not turn off power", are you saying you don't power off the drive, or you don't turn of the MC_POWER function block? I read your statement as you don't kill actual electrical power. MC_POWER should stay enabled. @Gustavo, not related to problem at all, but when you say 1.6 Nm is only enough torque to unscrew a loose bottle cap, I think that's a bit low. A quick mental math I use is 1 Nm is almost the same force as 1kG applied to a 10cm wrench. So 1.6kG applied to a 10cm wrench is still not a huge force, but more than enough to be felt if trying to turn the shaft by hand.

Post by alimans on OPC-UA Server, Symbol Set: Raise an error: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Post by micik on Python scripting - print whole project tree ^{CODESYS Forge talk (Post)}
Hello, I have found a script for printing device tree in Codesys project. This script is available as code snippet as an exmaple for using Python in Codesys. However I feel main documentation is lacking. For example, where can I find that object has "is_device" attribute? Code examples are given here: https://content.helpme-codesys.com/en/CODESYS%20Scripting/_cds_access_cds_func_in_python_scripts.html However, I have a question how to print the whole Project tree and not just devices? Of course I need to remove check: if treeobj.is_device: But simply removing this test condition will not produce what I want. I need to print PLC Logic, Application, ad other nodes in the Project tree. Where to find this documentation?

Hello, we have aproblen to connect our CODESYS OPC Client to the OPC Server. We installed the client according the CODESYS manual. We can browse the server and variables can be linked to the PLC. I created a self signed certificate for the CmpOPCUAClent as described. The server has a cerificate also. I copied the certificates to the trusted zone of server and client. But when it comes to data exchange we get an error message. "Communication error in data source OPC UA Library. Error ID : 7001 German : "Kommunikatinsfehler inder Datenquelle OPC UA -Bibiothek. Es wurde kein genauer Fehler angegeben. Fehler ID : 7001" It semms that there is no cerificate exchange. We are working with CODESYS 3.5 SP19 Patch 5. Can anyone here say something about this error or has an idea for a solution? Thanks.

Post by c3po on SNMP Communication with WAGO 750-8212 PFC ^{CODESYS Forge talk (Post)}
Hello folks, my problem is a bit bigger for just one question. So let's start with the easiest. But first, my system setup: It's a WAGO 750-8212 PFC with some I/O-modules. I try to communicate with the controlsystem over SNMP using the IIoT library from codesys. https://content.helpme-codesys.com/de/CODESYS%20Examples/_ex_iot_snmp_service.html Is there some expirience with this kind of communication? It's just about transfering some data from PFC to network and setting some analogsettings from network to the PFC. So my easiest question: Do I ever need the SNMP_Agent or can I use the SET / GET function as standalone, without the agent? (maybe some more questions will follow, if someone will answer to my request) thanks so far

Post by micik on Reverse bytes in an array ^{CODESYS Forge talk (Post)}
Hello, I'm getting the data in Codesys that is an array of 8 bytes. From this array, I need to foram LREAL number, however, because of different endiannes I need to reverse bytes in this array and then copy to a LREAL variable. For this I'm using a loop and it works OK. I wonder if there is a built in function to do this. I have found CAA Memory library but it has functions like reverse bytes in DWORD. But it seems it doesn't have what I need. https://content.helpme-codesys.com/en/libs/CAA%20Memory/Current/CAA_Memory/Reverse-Bit-Swap-ByteWord-order/ReverseBYTEsInDWORD.html What I need is a function to reverse bytes in an 8 byte array, or something similar.

Post by thim on Bibliothek mit C-Library erzeugt unerwarteten Fehler beim Aufsetzen des Projekts. ^{CODESYS Forge talk (Post)}
Um eine C-Library als Codesys Bibliotheksfunktion zu erstellen, bin ich den fünf Videoanleitungen von https://de.codesys.com/news-events/gut-zu-wissen.html gefolgt. Das funktioniert auch am Anfang gut, ich kann unter x86-Linux und RasPi-Linux auch die C-Libraries kompilieren. Wenn ich dann die Library aber wie in Video 4 gezeigt in der Codesys-Bibliothek verknüpfen möchte, (siehe Screenshot) bekomme ich schon bei Auswahl der Datei und auch danach bei Klick auf "Geräte auswählen" den Fehler "Der Dateiname sollte mit dem Bibliotheksnamensraum enden." angezeigt. Meine *.so Datei endet aber meinem Verständnis nach mit dem richtigen Namen analog zum Beispiel und wie es auch in meinem Projekt heißt. Mir ist unklar, was mir diese Fehlermeldung anderes sagen will. Hat jemand eine Erklärung? (Codesys V3.5 SP 20 + (64-bit))

Hi all, I am attempting to use the Control Win V3 soft PLC to control a WAGO 750-315 remote I/O system via modbus RTU communication. I am struggling to connect to the device. I have been following this tutorial: https://www.youtube.com/watch?v=YlRfkESaNds I have setup my devices as shown in the images below. I have verified that my com port settings are correct as I am able to connect/control using modbus simulator software with these settings. I have also connected to a modbus master simulator program as instructed in the video, but the orange triangles will not go away. Additionally, I have updated my settings to 485 using the PLC shell. I have also set "always update variables" to enabled (1). Serial port, PCI-Bus, and modbus serial device status all show as "Not Running."

Post by fredruel on ModbusServer became unreachable if reach maximum of 16 byClientConnections ^{CODESYS Forge talk (Post)}
Hello Fraziersedge, the solution of Codesys might be to update your codesys to the lastest version but it was not possible for us. In our Codesys V3.5 SP9 patch 8 I was able to fix this bug. I change my ModbusTCP slave component version or one of the sub component version (ex: SysSocket). Look at the picture in attachement that's the receipe that have work for us. When I got the bug my version of ModbusTCP slave was 3.5.5.0 with SysSocket at 3.5.6.0 and I change to ModbusTCP slave 3.5.14.0 with same version 3.5.14.0 of SysSocket event if I still use codesys V3.5 SP9 patch 8.

I want to read and write parameters of an IO-Link device using acyclic messages. I have a Cube67+ in Ethernet/IP, connected to an IO-Link master. In the datasheet, I can find the parameters required for the message (Service, Class, Instance, etc.). I see the function block "Set_attribute_single" in the "EthernetIP Services" library, but I'm not sure how to correctly send the index and sub-index for the IO-Link device. The class in the datasheet is 0x80 for the IO-Link Parameter Object, but it’s not present in the CPIClass enum. Is there another function block more suitable for configuring IO-Link devices? (similar to "iol_call" in PROFINET or what’s used in EtherCAT).

Hallo zusammen, ich habe Lizenzen für CoDeSys gekauft und auf einem Dongle installiert, in der Hoffnung, dass ich diese mit einem Verdin-Modul von Toradex verwenden kann. Leider wird mir aber im Lizenz-Manager angezeigt, dass der Dongle nicht gesteckt ist. Ich habe bereits beide USB-Ports versucht, aber die Fehlermeldung bleibt gleich. Ist das überhaupt die richtige Vorgehensweise über den Lizenz-Manager oder gibt es da noch eine andere Möglichkeit? Ich gehe mal davon aus, dass die Lizenz nicht automatisch erkannt und verwendet wird? Wie im angehängten Bild "usb" zu sehen ist, wird der Dongle auch als solcher erkannt.
