GE Fanuc 90-30 PLC Connectivity via Ethernet Gateway

[FN_10932963]

I am currently working on integrating a GE Fanuc 90-30 PLC with Kepware and have encountered an issue I’d like your assistance with.

I have successfully connected to the PLC using the GE SNP driver in Kepware through a direct USB-to-RS422 interface (specifically, the IC690USB901). Communication works as expected in this setup.

However, when I attempt to connect to the same PLC using a USR-N510 Ethernet-based serial gateway, I selected the GE Ethernet driver in Kepware, but the connection does not work.

Unfortunately, the GE SNP driver in Kepware does not seem to support Ethernet encapsulation (serial-over-IP) directly, Any guidance or documentation on this would be greatly appreciated.

You can use virtual COM port redirection software that creates a virtual serial port on your PC and forwards traffic to the USR-N510. This effectively tricks Kepware into thinking it's using a local serial port, while in reality, it's routing data over an Ethernet connection.

Examples:

• HW VSP3 or VSP3 MultiPort (by HW-group)

• Tibbo VSP Manager

• USR-VCOM software (provided by USR for the N510)

Make sure:

• The virtual COM port is set to the same baud rate, parity, and other serial settings as your PLC and the original SNP setup.

• The USR-N510 is configured in TCP Server mode, and the VSP is set as the TCP client connecting to it.

Once set up, point Kepware’s GE SNP driver to the new virtual COM port. It should behave exactly like the direct USB-RS422 connection.
