Hi sir, What is the difference between VIP communication and DP-DP(Profibus) communication? Is VIP faster?
In our STS Crane, 2 PLC's are used.
AC500 and AC800
And communication between them is by 2 means
VIP communication and DP-DP communication through a DP-DP coupler.
I wanted to know if the VIP communication is faster than DP-Dp communication, because i have seen important variables like Drive Fast Stop being communicated through DP-DP.
Kindly explain the 2 communications, would be much 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.
