Despite multiple troubleshooting attempts, I keep encountering the error message:"Unable to access the remote device." Details of my setup: PLC Model:6ED1052-1MD08-0BA2 Software Version:LOGO! Soft Comfort Version 8.3.1 I have verified the following: The Ethernet cable connection between the PLC and my PC is secure. The PLC's LAN indicator is green, confirming a physical network connection. I can successfully ping the PLC's IP address from my PC. The IP settings of my PC are in the same subnet as the PLC. Despite these confirmations, the software fails to establish a connection and continuously shows the "Unable to access the remote device" error. Could you please assist me in resolving this issue? If further diagnostics or specific steps are needed, I am happy to provide additional details ------------------------------------------------------------------------------------------ Split from LogoSoft Error "unable to access the remote device".

PLC Model. The device with part number 6ED1052-1MD08-0BA2 that you are trying to connect to, can only be configured using LOGO!Soft Comfort V8.4 or higher as you can see in the product description in the following link: "6ED1052-1MD08-0BA2: LOGO!12/24RCE, 8DI(4AI)/4DO, 400 Blocks" Therefore, in this case I would recommend you to update your LOGO! Soft Comfort software to V8.4 from the link below: "Download and installation instructions for LOGO! Soft Comfort Upgrade V8.4" In principle with this upgrade you will be able to communicate and you will no longer have this error. Best regards!

Soft Comfort software to V8.4 from the link below: "Download and installation instructions for LOGO! Soft Comfort Upgrade V8.4" If you mean this link: The website is deleted from Siemens because there is a download of a newer update/upgrade. Firmware update for LOGO! 8.4 basic devices and service pack 1 for LOGO! Soft Comfort V8.4
