Hi guys,
Which is the best way to create a communication between two robots?
Egd or profinet?
Robots should communicate between them and with the company network.
Thanks.

It will depend in part on what brand of robot, and the optional or built in protocols that they have. There are more communication protocols than what you mention and I do not even know what egd is.
At the moment robots has any option installed. Egd is a ethernet connection between robots.
You really need to tell brand and model when asking for help. There are many products out there.
Isn't EGD something only found on GE Fanuc?
When talking EGD (Ethernet Global Data) you are specifically referring to Fanuc. When the data you're sending, such as handshakes between two robots or positional data, is process related and time critical, EGD should be the preferred method as there is no "middle man" that controls the connection. Communication protocols of any type that are handled by an external device for example, a PLC, are subject to scan time delays of that external device and could result in process delays or missed data. We have handshake I/O mapped in a PLC between two dispense robots and there's at least half a second delay if not more from the time the output on robot 1 is turned on and we see the input in robot 2 turn on.
