2.1 GSD File
Accompanying each device are all the available device master data (GSD) of KROHNE
devices. The GSD contain information about the device which is necessary for setting up the
PROFIBUS-DP communication network. The corresponding files must be loaded into the set-
up system / master system before bus system startup procedures can begin.
As an example, for COMET 200 or COM PROFIBUS from Siemens this means:
••
all GSD files (*.GSD) into device master data directory, e.g. *\GSD
••
all BMP files (*.BMP) into the bitmap directory, e.g. *\BITMAPS
In STEP7 the GSD file is automatically copied into the appropriate directory by selecting
“Install new GSD” (from the HW-Config menu: EXTRAS). The bitmap is also installed at the
same time. After “catalog update” you can place the device in the project. After the transfer
into the connected assembly, cyclical communication (measurements and status) is
enabled.
The ESK3-PA signal converter completely supports the PROFIBUS-PA Profile V. 3.0. As a
result, the devices have two identification numbers and two GSD files. The Ident-No. “F201”
is part of the GSD file KROHF201.GSD and contains the complete device functionality. The
restricted functionality which is designed to permit using equivalent devices made by other
manufacturers as substitutes can be achieved by using the generic Ident-No. “9740” and
the GSD file “PA139740.GSD”.
PA139740.GSD
The restricted, generic functionality which can be achieved by this GSD file contains two
functional blocks (volume flow and volume meter).
To take advantage of this restricted functionality, you need the file PA139740.GSD.
But in advance you must use a Master Class 2 (operating tool) to alter the configuration
from “complete device functionality” to “substitute enabled minimal configuration”
(Ident_Number_Selector: Slot 0, Index 40, change the value of the bytes from 1 to 0).
Then you must set up the device again using PA139740.GSD.
