This is how to connect Cognex camera to a Doosan Robot

Configure these parameters

port = 10000
ip = "192.168.137.10"

then open a TCP connection to the camera

socket = client_socket_open(ip, port)

After connecting, the camera sends a welcome message and asks for a username and password.

receive = client_socket_read(socket, -1, -1)[1].decode()
client_socket_write(socket, "admin\r\n".encode())   # username + carage return, new line character

### Asked for a password ###
receive = client_socket_read(socket, -1, -1)[1].decode()
client_socket_write(socket, "\r\n".encode())        # password(empty) + carriage return, newline character

If successful, then you will get a logged-in message.

receive = client_socket_read(socket, -1, -1)[1].decode()

After the login procedure, trigger the camera. This function only works if the Cognex camera is on Online Mode

client_socket_write(socket, "SE8\r\n".encode())
wait(3)

triggerstatus = client_socket_read(socket, -1, -1)[1].decode()[:-2]

if triggerstatus != "1":
    tp_log("Trigger failed: " + str(triggerstatus))
    return 0

After triggering the camera, We can get the cell value from the Cognex table cell.

cel_data = "GVC019"
client_socket_write(socket, (cel_data + "\r\n").encode())   # GVC013
getvaluestatus, rec, _empty = str(client_socket_read(socket, -1, -1)[1].decode()).split("\r\n")

if getvaluestatus == "1":
    # tp_log("GetValue successful: " + str(getvaluestatus))
    rec = str(rec).split(",")
else:
    tp_log("GetValue failed: " + str(getvaluestatus))

After get the cell value, we need to close the connection

client_socket_close(socket)

This was the end of this tutorial, I hope it helped you. Good luck with your project!
