Three types of communication protocols are currently available:
•
Cyclical data exchange between master and slave (most common type of communication, to
date) -- DP-V0 protocol.
•
Acyclical data exchange between master and slave -- DP-V1 protocol.
•
Deterministic data exchange between different slaves -- DP-V2 protocol.
The ATM60, ATM90 and KHK53 encoders with Profibus interface support the DP-V0 communi-
cation mode.

This version provides the basic functionality of DP including the cyclical data exchange, as well
as different types of diagnostics.
