Profibus-DP is a high speed communications
network and protocol, that allows
large amounts of data to be transferred
quickly to and from network nodes.
The Profibus interface will detect
the network data rate, and automatically
synchronise to it. The Profibus-DP
interface for Mentor II is a slave
node only.
Profibus-DP networks are "centralised"
systems, requiring a master
controller (usually a PLC) which
controls all communications
with slave nodes on the network.
The Profibus interface for Mentor
is a slave node only.

| Key
Features |
| |
| - |
Easy fit add on card for
Mentor II |
| - |
Supports data rates up
to 1.5 Mbits/sec |
| - |
Automatically recognises
the network data rate |
| - |
Supports three 16 bit
cyclic data channels |
| - |
Full cyclic data channel
mapping allows any cyclic
data channel to control
or source from any drive
parameter |
| - |
Default mappings -
* Speed/frequency feedback
* Torque feedback
* Status word provides status
bits about 15 drive functions,
eg drive healthy, drive
running, at
speed etc.
* Speed/frequency reference
* Torque feedback reference
* Control word allows ENABLE,
RUN and DIRECTION signals,
plus reference selection
and user
bit parameters to be transmitted
in one cyclic data word

| - |
Network Loss detection
will trip the drive (if
enabled) if the network
connection is lost |
