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!

Since the request works correctly in the browser and returns the full JSON, it seems the API itself is fine. The issue might be related to how the WebClient is reading the response. Sometimes the response is received in chunks or requires waiting until the full content is available before parsing it. You might want to check if the WebClient is reading the complete stream or if there is a buffer/timeout run 3 setting that stops it too early.

JOG continues in WCS ( SMC_GroupJog2 )

I'm using the SMC_GroupJog2 block from the SM3_Robotics library for manual movement of an AxisGroup in WCS coordinates. The observed behavior is: When pressing X+, the X-axis starts moving correctly. If I press Y+ during the movement, the block interrupts the current movement and starts a new movement in X and Y. If I release any button, all axes stop, even if another button is still pressed. Example: Pressing X+ → X moves Pressing X+ and Y+ → X stops momentarily and starts XY movement Releasing X+ while holding Y+ → all axes stop The expected behavior would be: to allow simultaneous continuous movement on multiple axes to not interrupt movement when another axis is added or removed. Is there a correct configuration of SMC_GroupJog2 to achieve this behavior, or is there another block more suitable for continuous manual jog in AxisGroup (WCS)?

I need to add a button to the Visualization to close it. And create a shortcut on the Windows desktop to reopen the Visualization. This is necessary to configure, for example, a local IP address. Is this possible? What command closes the Visualization? Which program opens Visualization? System: Win10 Codesys: Control RTE V3 x64 Program: Codesys V3.5 SP20 Using only a touchscreen monitor, without keyboard and mouse.

How do I negate an output signal from an OR gate. I have tried right click to no avail and I cannot find an propriate NEGATE box? I want to save the output from the block to an inverted variable.

Anyone have problems with trend in lastest release - SP21 Patch5? Does not record data, stores only zeros to the sqlite database and flatliners at zero in trend/trace views. Worked in P4.
