Post by martin-k on Beispieldateien finden / Inhalt der Packages ^{CODESYS Forge talk (Post)}
Hallo, mal wieder war der Fehler vor dem Computer, bzw. waren es die Programmierer. Die Dateien sind tatsächlich im Ordner C:\Users\BENUZTERNAME\CODESYS Examples Aber nicht in dem der vor dem Computer sitzt, sondern im Administrator-Verzeichnis. Eine mächtig dämliche Sache. Und das alles ohne Hinweise in irgendwelchen Anleitungen oder Meldungsfenster beim installieren. Bei meiner suche mit *.project habe ich natürlich keine Adminrechte, deswegen wurde mir nichts angezeigt. Danke an alle die meine Beiträge gelesen haben. Danke an alle die darüber nachgedacht haben :-) Vielleicht hilft mein Thread mal jemandem. Gruß Martin PS: Mache Firmen nennen die Beispieldateien nicht Examples sondern Samples.

Post by nz-dave on Bool turning on in case stament in wrong state? ^{CODESYS Forge talk (Post)}
I had the FB called via a for loop to call a few instances of my FB I have removed it the for loop and just called them 1 by 1. Seems to have sorted the problem. tho, i have other FB's and for loops doing the same thing but they are all fine. below is basically what was happening. var: mVibrator : ARRAY[1..GVL_Settings.Number_Of_Products] OF Main_Vibrator; end_var Controller(PRG) call: FOR v := 1 TO GVL_Settings.Number_Of_Products BY 1 DO; mVibrator[v] (); END_FOR So at state 30: the mVibrator[1].start was turning on 30: Main_Mixer.Start := TRUE; Process_State := 2; IF Main_mixer.Done THEN Main_Mixer.Start := FALSE; Control_State := 40; END_IF but its not till state 50: that it is actual in the code. 50: Main_Suction_valve.Open_Input := TRUE; mVibrator[1].Start := TRUE; Process_State := 4; IF GVL_Weigh_hopper.LoadCell_Weight = 0 THEN Main_Suction_valve.Open_Input := FALSE; mVibrator1.Start := FALSE; Control_State := 60; END_IF Thanks for your input.

Post by sercan on Does G75 work when SMC_NCInterpreter is used? ^{CODESYS Forge talk (Post)}
When a G75 command is received in a SoftMotion+CNC project, SMC_NCInterpreter does not generate any error commands, but the command does not continue execution! There is information about SMC_NCDecoder in the documentation of the G75 command. Is this command only supported by SMC_NCDecoder? Can the G75 command be used with SMC_NCInterpreter? Forexample: G75 ; RUNNING G01 X$Settings.X$ Y$Settings.Y$ Z$Settings.Z$ ; - G75 ; - G01 X100.0 Y200.0 Z300.0 ; -

Post by fleaplc on CPU + EtherCAT redundancy ^{CODESYS Forge talk (Post)}
Hi all, for a new project I'm looking for a redundant controller with EtherCAT fieldbus I/O. Actually I'm using Beckhoff and it works great! but there's not a solid redundancy yet... Does someone get experience for industrial application (not raspberry) for a redundant Codesys system? If yes please share some info (CPU / OS type, bus, number of managed I/O,... and especially feeling feedback (stability, bugs, performance)... Every suggestion is kindly appreciated!! Fabrizio

Post by beavel on Feature Request: Text List Formatting ^{CODESYS Forge talk (Post)}
Hi everyone, I'm working on a multilingual help system within a CODESYS visualization project and have run into a limitation with the current text list (.tlx) functionality. Right now, text list entries only support plain text, which makes it very difficult to format longer help texts in a readable way. For example, I’d like to: Use bold headers and larger font sizes for section titles Display variable names or keywords in italics Avoid having to split content into dozens of separate entries just to apply different styles This becomes especially unmanageable when supporting multiple languages — duplicating layout logic across languages is not scalable. Would it be possible to implement a Markdown text functionality for text list entries ? For example: #Header ##Sub-header 1.ordered 2.list 3.fun 4.times Alternatively, is there any existing workaround or planned feature that allows for styled text blocks without fragmenting the content? Thank you in advance and have a nice day :)

Post by egr99 on Modbus TCP Server connection is ESTABLISHED but all holding registers are value 0? ^{CODESYS Forge talk (Post)}
Hi there, Read the above description and experienced the same: Reading coil/discrete input/input register/holding register doesn't fill the mapped I/O variable. Any suggestions? Defined (see attachment): - Ethernet (with parameters according to the used Ethernet adapter of my Windows 11 laptop) - -Modbus TCP Client - - -LOGO231 as Modbus TCP Server - - -WS242 as Modbus TCP Server (WaveShare Modbus TCP <-> RTU converter) - - - -WS242_01 as Modbus Server, COM port (slave-id 1 RTU) - - - -WS242_03 idem (slave-id 3 RTU) - - - -WS242_11 idem (slave-id 11 RTU) Writing coil/holding register works from a mapped I/O variable works fine. Verification of Modbus traffic with WireShark: QUERY to and the RESPONSE of all slave-ids are correct Status of all defined is CONNECTED, RESPONSE_SUCCESS, RUNNING etc. Request counters increase with expected frequency. Error counter = 0. (To have all counters works fine I had to change Modbus TCP Client's parameter OptimizationON to FALSE). LOGO231 works fine: values in mapped I/O conform expectation WS242 without Modbus Server, COM port and with defined channels (for only 1 slave-id possible) works fine. PLC Settings: Update I/O while in stop: I see xBusy changing from FALSE to TRUE and vice versa. Always update variables: Enabled 1

Post by teichhei on The selected container ... does not fit your ticket ^{CODESYS Forge talk (Post)}
Hi, When trying to activate a control Basic L license on a Wago PFC200 750-8203 the error The selected container ... does not fit your ticket comes up and won't allow licensing. I have deleted the /var/opt/codesys/cmact_license/ content 3 times and the container number changed each time after a reboot, but the problem persists. Not a happy first time experience with those weird application based licenses. IDE is 19.20. This was a e!Cockpit FW22 PLC and I used Deploy Control SL to make the green web interface red. WBM shows Codesys 2 and e!Runtime active which is a bit weird. What do I do now? Regards Heinz
