A.5 Profibus Option (P/N 1295-275)
Profibus is a vendor-independent, open fieldbus standard
for a wide range of applications in manufacturing
and process automation. Vendor independence and
openness are ensured by the international standards
EN 50170, EN 50254 and IEC 61158. Profibus
allows communication between devices of different
manufacturers without any special interface adjustment.
Profibus can be used for both high-speed time critical
applications and complex communication tasks. Use
of special Profibus media is required.
For more information about Profibus, see
profibus.com. Technical information on the Woodhead
Connectivity / SST model
SST-PFB-SLC module which is used in the Vertex M
is available from http://www.woodhead.com/products/
automation/networkinterface/PLCBackplaneModules/.
The data map used by the Profibus interface is shown
in Table A-5. The interpretation of the data is in
A-3 and Table A-4. The network management tool will
need a .GSE file to describe every slave on the network.
The vertex.gse file can be copied from any Vertex M at
c:\hmi\Profibus\vertex.gse.
A.5.1 Termination
The Profibus adapter PCB assembly shown in Figure
F-3 facilitates using standard large Profibus connectors
without creating mechanical interferences with the back
panel of the Vertex M rack. Additionally, this functions
as a Profibus terminator if JP1 through JP3 are shorted.
If termination is not desired then JP1 through JP3
should be cut as shown. This is Honeywell Analytics
part number 1295A0372.

A.5.2 Profibus Module Configuration
The Profibus interface is shipped from the factory with
the address set to 3, the speed set to 19200 baud, and
the memory length set to 122 words.
The memory length to can be reduced to 41 words
if only alarms and fault are needed. Changing any of
these parameters requires Procedure 1.
