What is the difference between VIP communication and DP-DP( Profibus)Communication between 2 PLC's? Is VIP faster?
I would like to know what is the difference between VIP communication and DP-DP communication between 2 PLC"s
Our Crane has 2 PLC's
AC 500 and AC 800 and 2 means of communication is used DP-DP with a DP-DP coupler in between and VIP communication.
Is VIP more faster? I have also noticed that important variables like Drive Fast Stop signal is transferred by DP-DP.
Kindly explain the difference between the 2. Would be most appreciated.

VIP : Vendor Internet Protocol; Each VIP message consists of a header part and a data part. The protocol defines the message header and the format specifies representation of data in the data part.
DP-DP communication : Profibus COmmunication Protocol
Interms of Speed, Profibus Communication is preferred over VIP protocol.
