5.2 About the PROFIBUS Protocol
PROFIBUS (Process Field Bus) is a widely-used, open-standards protocol
created by a consortium of European factory automation suppliers in 1989.
PROFIBUS is a Master/slave protocol. The Master establishes a connection to
one or more remote slaves. When the connection is established, the Master
sends the PROFIBUS poll messages (called telegrams in PROFIBUS) to the
slave or slaves. The MVI56-PDPMV1 module works as a Master only. It cannot
be a slave to some other Master.
The MVI56-PDPMV1 module also acts as an input/output module between
devices on a PROFIBUS network and the Rockwell Automation ControlLogix
processor. The module uses an internal database to pass data and mailbox
requests and responses between the processor and the slave devices on the
PROFIBUS network.
PROFIBUS specifications include a variety of network types. The network type
supported by the MVI56-PDPMV1 module is PROFIBUS DP version 1, which is
designed for remote I/O systems, motor control centers, and variable speed
drives.
