Establishing the Ethernet connection

The connection between the computer where the MecaMotion programming software is located and the press is made via an Ethernet bus.

This Ethernet connection is used to send the various part programs, envelopes, parameters and user variable association to the press. The reception of the force/position curves is also done through this connection. In addition, it allows the press to be controlled in standalone mode.

You can change the IP address of the press, the subnet mask and the gateway address by entering them in the "new address" section, then click on the "Read and write" button to make the change. (this may take some time)

When you change the IP address of the press, the "IP Address" field in the "Hardware" window is replaced by the new address, your computer will then be automatically reconnected to the press after the address change.

Be careful, if you make changes and the address of your computer is no longer part of the same network as the press, the window below will appear (figure 5).
