We attempted to connect the X20CP0292 unit for testing purposes using X20PS9500 modules.
Although the PLC is detected via Automation Studio, a stable connection cannot be established.
Connection attempts were made through both Ethernet and RS232, but neither method was successful.
I would appreciate your guidance on whether there is an alternative method or a specific procedure
to successfully establish a connection with the device.
could you please specify more in detail what instable connection means?
For exampe “no online connection possible at all”, “connection breaks when downloading project”, “connection breaks when opening watch”, or similar?
Any error messages thrown by Automation Studio?
Is it an empty PLC, or is already a project installed on it?
Is the device pingable via ethernet?
Any detail will help us to possibly identify the cause and to give concrete advise, thanks!
The PLC is detected within Automation Studio, but when trying to connect, it is impossible, it always remains in OFFLINE state. Attempts were made to connect via Ethernet as well as RS232, and the PLC showed no change either in the program or through its LEDs. The computer does detect that a device is connected; however, once inside Automation Studio, the device cannot be found. It was also switched to BOOT mode, but connection was still not possible.
Answering the questions:
1. No, it does not show any error; it simply does not detect/read it.
2. It has a project already, but since the PLC cannot be read, there is no direct way to know the project.
3. Yes, it can be pinged.

How did you connect to the PLC?
Could you try to create a new TCPIP Connection, then write the IP, at the end click in Connect? (workaround reported by Vanessa for different connection issue, but maybe it helps in your case too)
Hi @Luz_Barboza , I would recommend restarting your laptop, restarting AS, and power cycling the X20CP0292 if you have not already. I have gotten into similar edge-case states in the past which were fixed by a hard reboot of AS (which restarts PVI in the background) and the controller.
Additionally, if you have the AS project that is running on the PLC, make sure that “Activate online communication” under ANSL and INA parameters are enabled in the Ethernet port configuration in the Physical view. These should be on by default, but worth checking in case they were turned off.
