In the device selection. Do not filter on Phoenix. Remove this filter and first add an Ethernet Adapter from CODESYS. To this Ethernet adapter add the Profinet Controller. After this you can filter on Phoenix devices in the "add device dialog".

No, you can´t. I have only tried different browsers on my PC and then on my HMI device. Unfortunately the device´s browsers did not support pdf file as I needed so I had to switch to *.txt.

Most likely related to the Device Diagnostics functionality. Double click on your device (PLC), go to the tab "PLC settings". Enable the advanced option "Enable diagnosis for devices". Build your application again.

I'm having the same issue.I think it may be something related to the device adress that changes depending on the network i'm using, but now i don't have access to the one i used while setting my user. Did you find any solution for this?

Post by jeroenaero on Targetvisualisation full screen with CmpTargetVisu settings ^{CODESYS Forge talk (Post)}
Hi, How can i display targetvisualization in full screen on the target device? I installed Targetvisu For Linux SL 4.16.0.0 on target device which contains Raspberry PI 64bit PIXEL desktop. When i connect my PLC program to the remote targetvisu, the targetvisu displays for 60% horizontally. We contacted CODESYS and they said it is a bug. they had a workaround, and with the settings below added to the file /etc/codesysvisualization/CODESYSVisualizationTV.cfg, the targetvisualization display for 100%, but with the taskbar at the top. VisuClient.BestFit=1 ;VisuClient.ScaleTypeIsotropic=0 VisuClient.FillWholeBackground=1 [CmpTargetVisu] WindowPositionX=0 WindowPositionY=0 WindowSizeWidth=1280 WindowSizeHeight=800 WindowType=2 How can we let it display fullscreen without taskbar?

Post by mp9876 on Device logon problem following fresh install ^{CODESYS Forge talk (Post)}
Yes it had been the case I believe as I have seen that message regarding they were not the same. I had update the device though to match them and that still did not fix the problem. I gotta say I wanted to get out of that situation and attempted a lot of things and then I did two things at the same time that fixed my problem: Wiped the 64 bit version and installed the 32 bit version Installed latest SP20 I wish I knew which one of these actions fixed the problem but now I gotta catch up on this IDE learning; it's been quite a learning experience I have to say! Thank you very much for your time and advice; much appreciated!

Post by akrawczyk on Dynamically enabling/disabling Modbus slave devices in runtime (performance issue with timeouts) ^{CODESYS Forge talk (Post)}
Hi everyone, I'm working on a CODESYS-based project running on a Weintek cMT2078X HMI with a built-in CODESYS runtime. The system communicates with multiple Modbus RTU slave devices, arranged in a cascade. The number of connected units can vary between 2 and 8, depending on the installation. Each slave has 17 Modbus channels, which are polled cyclically every 5 seconds. The issue is that when fewer devices are physically connected (e.g. only 3 out of 8), the Modbus master still attempts to communicate with all configured slaves. This leads to massive delays due to timeouts (currently 200ms per channel). For one disconnected device, that’s: 17 × 200ms = 3.4 seconds of delay per polling cycle, and this quickly multiplies with each additional missing slave. This behavior significantly degrades the system's performance and responsiveness. We attempted a workaround where we tried to trigger polling based on a variable in the PLC program, but this caused instability and even led to hardware hangs/freezes on the cMT2078X – likely due to clashes in how the Modbus polling engine and program logic interact at runtime. My main questions are: Is there a way in CODESYS to dynamically enable/disable Modbus slave devices at runtime, using a BOOL or INT variable (e.g. indicating number of active slaves)? Can devices or channels be conditionally polled or temporarily disabled without removing them from the device tree? Are there any best practices or examples for handling variable numbers of Modbus slaves in scalable systems like this? Would splitting communication across tasks or interfaces help reduce the impact of timeouts? Any advice, documentation references, or architectural suggestions would be extremely helpful. I'm looking for a robust way to dynamically scale slave polling without degrading system stability or performance. Thanks in advance!

Post by testlogic on Sending Sequential Modbus TCP Packets ^{CODESYS Forge talk (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.

I have a serial Modbus RTU communicating to the Slave device. But when the control system is not in Run there is no power applied to one of the Modbus Devices. Can I enable / disable the communications to that Modbus Slave in the code based on my running mode, so I don't get all the errors?

I just had the same problem in 3.5 SP19 Patch 6. Trying to use a textlist for Combobox Integer element. The textlist cannot be selected in the IDE, and is not found when manually entering the name. The textlist is copied to the device, but is not used. Can confirm, that copying an existing textlist and renaming it does work.

Post by trusty-squire on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Just a stab in the dark, but you might want to check the Dynamic Limits (accel, decel, velocity, jerk) in the Codesys SoftMotion device configuration, as well as checking similar limits on your servo drive? Are you seeing any errors, or does the MC_SetPosition FB get marked as complete?

Post by teichhei on The selected container ... does not fit your ticket ^{CODESYS Forge talk (Post)}
After correspondence with Mr Schwellinger from Codesys the resolution for this was to uninstall the SL 4.14 and install SL 4.13 on the device. Once this was done the licensing worked as expected. I noted that the container then showed a Version 3.00 and not 0.00.

OK, I figured out that I can simply define all the sensors as 16 bytes IN/OUT, even if they are not all used. EDIT: The negative effect is that each bit is taken into account as an I/O for the license, even if not used.

For reference, it was just me being unfamiliar with EtherCAT in CoDeSys. Anyone with knowledge who would have opened the ScanResult screenshot would have identified that the preceding EK1100 was the device missing in the library. Bottom line - Do something else for a while and then get back at it with fresh eyes!

1) Based on your first screenshot. Do NOT filter on "Phoenix". Then first select the Ethernet adapter (of CODESYS) and add this to your device. 2) Then to this Ethernet adapter add a Profinet Controller of CODESYS. 3) Then to this Profinet Controller, add your Phoenix Profinet coupler/adapter.

Try changing the port mode to digital input for each port you want to have 2 inputs in the connection settings for the device. I've successfully used ports for inputs on an AL1920 this way, I think the procedure should be the same for an AL1332.

Hi! I'm still on the hunt for drivers for example TCA9548 and a list or somewhere where all devices for raspberry is gathered. as this post is quite old I'm hoping/gussing that there is somewhere where work after 2021 is gathered? Or has the raspberry part if the community slowed down on creating device drivers?
