Communication protocol 119
Communication protocol
What this chapter contains
This chapter describes the PROFIBUS messaging used in the
communication with the drive and in PROFIBUS slave device
configuration messages.
PROFIBUS DP
The FPBA-01 module supports the PROFIBUS DP-V0 and DP-V1
protocols according to the IEC 61158, IEC 61784 and EN 50170
standards. PROFIBUS DP-V0/DP-V1 is a distributed I/O system
which enables the master to use a large number of peripheral
modules and field devices. The data transfer is mainly cyclic: the
master reads the input information from the slaves and sends the
output information back to the slaves.
The FPBA-01 module uses so-called PPOs (parameter/process
data objects) in cyclic communication and also supports standard
telegrams 1 and 2. See section Cyclical message types on page
135 for the supported PPO messages and standard telegrams.
