Not sure, but maybe it related to the style. Go to the Visualization Manager in your project and see if a style is selected, or choose another style to see if this helps.

Post by brell on Automatic xExecute NBS.TCP_write ^{CODESYS Forge talk (Post)}
I've recently started experimenting with CODESYS for a project and am fairly new to it. I'm currently working with Function Block Diagrams (FBD) to set up TCP communication between a server and a client, where the client is implemented as a Python script. Once the communication is established, my connection status changes to True, which is the expected behavior. My challenge arises with the TCP write module, which requires the xEnable_write flag to toggle between True and False. If xEnable_write remains True, the module only performs a single write operation. To address this, I introduced a falling edge trigger (F_TRIG), expecting it to help in toggling xEnable_write and it does, However, I've encountered an issue where in the beginning after connxion established I need to manually set xEnable_write to True for the system to work as intended. I'm looking for a way to automate this process so that xEnable_write becomes True automatically upon establishing a connection . Initially, I tried setting xEnable_write to True from the start, but this approach didn't work well since it left the flag permanently True, preventing further toggling. I also experimented with using a TON timer, but I faced similar issues. I am seeking a solution that automatically toggles xEnable_write between True and False after a connection is established, ensuring continuous write operations without manual intervention. Any advice or guidance on how to achieve this would be greatly appreciated."

Hello You'll need to write a proper sequence to send, then wait for confirmation, and then move on to the next step. Use the CASE statement in ST. It's perfect for creating a sequence.

Which plc type is it: Either use Automationserver to do this or save the project archives instead of projects or use the source dowload function and reopen the application from plc. So you need to chose one of them.

Post by tvm on Timer On Vijeo ^{CODESYS Forge talk (Post)}
Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

Only logged in to agree with the above. So counter intuitive. Why does an associated action force the variable when the step it is associated to is not active? Makes no sense at all, is terrible to debug and costs a lot of time. Such as shame.

sorry I missed to say how to do this just update the runtime. (extract latest debian package out of the CODESYS package) but 8n this case an update all to the latest version including CODESYS is probably the easiest option now.

Hello everyone, I’m currently working on setting up an EtherCAT Master using CODESYS on a Raspberry Pi, and I’ve run into some issues I could use help with. Project Setup: EtherCAT Master: Raspberry Pi with CODESYS Control for Raspberry Pi 64 SL installed EtherCAT Slave: Beckhoff CX5130 with EK1200 coupler I/O Module: EL2008 License Module: EL6070-0033 I’ve installed the required CODESYS packages and the Linux gateway on the Raspberry Pi. In my project, I added the EtherCAT Master with the appropriate port settings and scanned for devices. The CX5130 shows up as a slave, but communication fails—I'm getting error messages and can't access the outputs. Specifically: The EL2008 output module isn’t recognized properly in CODESYS. There’s no option to communicate with it through the CX5130. I’ve tried connecting via both the Raspberry Pi’s built-in Ethernet port and an external network card. I've attached screenshots showing the errors I get in CODESYS and the devices detected via TwinCAT for reference. Any help or suggestions would be greatly appreciated! Thanks in advance!
