Question

TCP/IP socket communication (raw ethernet)

Is it possible to connect KepWare to a device that uses TCP socket communication? So, basically to send a command to the device (IP/port) and receive a string response?
The device is Tettex 2293
Command I’d like to send is ‘*IDN?’\r\n
Expected response is a model and a serial number in a string.

Greetings!!

We sorry for the late response.
 

Yes, but not directly with standard Kepware drivers.

Kepware can communicate over TCP/IP, but for a device that expects raw TCP socket commands like:
*IDN?\r\n
and returns a plain text string response, you would typically need:

Kepware UDD (Universal Device Driver) with custom logic, or
Advanced Tags/IoT Gateway + middleware, or
A custom OPC server/client that handles the socket communication.

If the Tettex 2293 only supports a raw TCP socket protocol (not Modbus TCP, OPC UA, Ethernet/IP, etc.), 
Kepware alone cannot simply open a socket, send *IDN?, and read the string response as a tag.

Short answer:  Possible with custom integration (UDD/middleware).Not natively supported by standard Kepware drivers for raw TCP socket string exchanges.
