Hi Leute , ich bin neu hier im Forum und habe seit kurzer Zeit mein eigenes SPS-Projekt. Ich stoße hin und wieder an Probleme aber habe diese auf kurz oder lang gelöst. Nun zu meinem Problem: Als Projekt habe ich eine Kühlwassersteuerung , die einen Relativdruck einließst, und anhand desssen Werte dann einen Frequenzumrichter ansteuert. Z. Bsp. 5Bar -> FU auf 70Prozent. Ich lese in Codesys den Analogwert mit der Wago A20_750_455_020 ein. Dieser Wert wird umgerechnet mit LIN_TRAFO in 0-10 (Bar)und und wird dann über einen PID Regler geregelt. (Bibliothek UTIL). Dieser Wert wird dann wieder für die Ausgangskarte Umgerechnet (LIN_TRAFO) . Nun zu meinem Problem : Die Ausgangskarte nimmt nur einen Word Datentyp und meine Bausteine haben den REAL Datentyp. Wenn ich einen Konvertierungsbaustein nehme, Schmeist mir Codesys einen Fehler und das Programm wird geschlossen. Könnt Ihr mir helfen? Vielen Dank im Voraus (Datei habe ich angehängt). Die Ausgangskarte ist eine Wago 750-555-08

Hi, I don't know if I'm in the right place or if it's even possible... I'm looking for a way to address a Profinet device with Record Read and Write from my own PC. I actually only need very few commands to configure our device. This means setting the MAC address and a serial number. We would like to do this from a C# program. Now we are looking for a library or something similar. Since you can do it from Codesys, I thought there might be a DLL or something similar that you could use for this. As I said, we don't want real-time queries of the cyclic data but only record read/write. Does anyone have any helpful hint? Thanks in advance

I have developped a function block 'Axis' the inherits from 'AXIS_REF_SM3' -> FUNCTION_BLOCK Axis EXTENDS AXIS_REF_SM3 In my global variable list I define a variable MasterDrive of type Axis and assign Axis1. Axis1 is a virtual drive (AXIS_REF_VIRTUAL_SM3). This type should inherit from AXIS_REF_VIRTUAL. VAR_GLOBAL MasterDrive : Axis := Axis1; However I get the error 'Cannot convert type'. What is the way to obtain what I want : function block inheriting AXIS_REF_SM3 and initialising this function block with a Softmotion virtual or real axis?

Good morning, I think that the mode Simulation does not support the Softmotion functionnality because it runs the CODESYS process with normal priority wich is not a good thing for real-time behavior. If you want to test your PLC project, please use a Codesys Control Softmotion (and your computer must have the Ethercat driver installed) or much easier, download your code into the C6 Smart. BR

Hallo Zusammen, ich versuche die Bibliothek FloatingPointUtils.compiled-library-v3 zu benutzen. leider kommt dabei folgende Fehlermeldung: Kein Quellcode für dieses Objekt... (siehe Anhang) Wie kann ich diese Bib einbinden? Kann ich diese irgendwo herunterladen? Mein Ziel ist es ein DWORD (float) in ein REAL umzuwandeln. ICh hoffe, dass ich dies mit der Funktion HexStrToReal machen kann. So wie hier: https://gregstoll.com/~gregstoll/floattohex/ convert to float... Oder gibt es bei Codesys einen anderen Weg? Ich verwende v3.5 SP20 Patch 1 + (32Bit) Grüße Sebastian

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 testlogic on Sending Sequential Modbus TCP Packets
CODESYS Forge

(Post)
I have a Modbus TCP slave device where I need to do sequential writes to the same register. The register I'm writing to is kind of like a command line, each packet is a command word encoded in Hexadecimal. I am having difficulty implementing this system in CoDeSys 3.5 SP19. I feel like the structure of the program should be something along the lines of (Pseudocode): ModbusTCPSend(Command Register, Command1) ModbusTCPSend(Command Register, Command2) ModbusTCPSend(Command Register, Command3) I have tried to implement this with a rising edge trigger wMot1OPCode := 16#E1; //Stop Motor & Kill Program xMot1SendOP := TRUE; //Send OP on rising edge xMot1SendOP := FALSE; //Reset wMot1OPCode := 16#9E; //Disable Motor xMot1SendOP :=TRUE; //Send OP on rising edge xMot1SendOP := FALSE; //Reset Where "wMot1OPCode" is the IO map for writing to the command register, and "xMot1SendOP" is the rising edge trigger for that modbus channel. However, this doesn't work. The device never responds to the modbus commands. It seems like the trigger variable is switched too quickly for modbus to send the packet. I know the modbus register is working, because I can set the channel to cyclic and the device will respond. However, I can't use this reliably because I need each command to be sent once, in order. Cyclic keeps re-sending the commands and seems like it could miss a command as well if one was sent in-between cycle time. I have also trying using the Application trigger as described by https://faq.codesys.com/pages/viewpage.action?pageId=24510480, but this is also not working for me. See attached picture for my FBD code. This seems like a simple function, I can't tell what I'm doing wrong here. Thanks for the help.
