Post by infinitetool on No connection could be made because the target machine actively refused it ^{CODESYS Forge talk (Post)}
Hi! I'm having trouble connecting to a device in Deploy Control SL. I'm able to see the device is available during a scan, and I can ping the device as well, but when I try to connect I get the message "No connection could be made because the target machine actively refused it". I've worked on this for hours including turning off the firewall on the device PC but nothing seems to work. The device is running a fresh install of Windows 11 IoT Enterprise 2024 and the Development System is 3.5.21.50 running on Windows 11. Thank you in advance for any ideas!

Post by wistaro on Hardware compatibility with Linux RealTime PLC ^{CODESYS Forge talk (Post)}
Hello, I am currently using Codesys Control RTE Softmotion V3 to control my servo-drives in CAN, EtherCAT and PROFINET IRT. I am using a PC with Windows 10 with the following boards: - PEAK-CAN PCIe board (for CAN and Softmotion); - Hilscher CifX with firmware 3.X and SysDrv3s driver (for PROFINET IRT); - Realteak standard NIC (for EtherCAT). I would like to switch to Linux (Debian), because this computer is old, slow, and outdated (Windows 11 is far from being compatible with this computer). Before doing this, I would like to be sure of the compatility between my 3 boards and Codesys Control Linux SL. Otherwize, I will stay on Windows 10 and use it in an isolated environnement. Thanks for your advices. Regards,

Correct, my Device architecture says "None" is this position. A missing config somewhere?

Post by rik123456 on Alarmmanagement – Dynamic Alarm List ^{CODESYS Forge talk (Post)}
Hi, I had a question about alarm management in the CODESYS visualization. I am currently investigating to what extent the alarm visualization can be built dynamically. In my program, I have developed a motor block that is used for multiple motors. When the emergency stop of one or more motors is activated, the corresponding motors are displayed in the alarm list (see image). This works quite well. I achieved this by linking variables to a latch, after which a piece of code displays the motors that are in emergency stop. My question is: do I need to create a separate latch for each motor or can I use a single latch to display multiple alarms of a motor underneath each other? This would then look like this: Time…: M1 Emergency Stop Active Time…: M4 Emergency Stop Active

Post by alexgooi on Network variable stops sending ^{CODESYS Forge talk (Post)}
Hi Reinier, What usually works for me is settings it up in the following way: In the sender block make sure that the list identifier is unique for the whole installation (this is only relevant when you have multiple senders in 1 network). When you are linking the NVL to a file make sure that the path to this file doesn't change. In my experience the NVL stops working when you change the working directory and afterwards open the NVL in de Codesys IDE. If this doesn’t apply to you application, you could also try to change the port number, maybe there is an other process making use of port 1202. Kind regards Alex
