Operating the AX2500/2850 over a Wired or Wireless LAN

To operate over the network two computers are required, as show in Figure 100 below. The top computer is connected to the controller via its COM port. Both computers are con- nected to a TCP/IP network.

Roborun Utility

FIGURE 100. Operating the controller over a LAN

The computer connected to the controller must run a communication server program named roboserver. This program is automatically installed in the Start menu when install- ing the Roborun utility. This program’s function it to wait for and accept TCP/IP connection requests from the other computer and then continuously move data between the network and the COM port. When launched, the screen shown below appears.

The second computer runs the Roborun utility. To establish contact with the server pro- gram, click on the “Change COM/LAN Port” button and enter the IP address of the second computer. Communication should establish immediately.

When the two computers are connected, it will be possible to operate the motors and read the controller’s operating parameters in the Roborun Run window.

Note that it is not possible to use this configuration to change the controller’s parameters or update the controller’s software.
