Connecting the PROFIBUS cable
The PROFIBUS cable should only be connected after proper completion of the active
slaves configuration in ibaPDA. This is to make sure that no slave number has been
used twice.
A conflict of several slaves with the same number may cause a complete breakdown of
the communication on the PROFIBUS and may finally lead to a plant downtime.
It makes sense to configure active slaves, if data have to be acquired with the device
that are not sent on the PROFIBUS anyway.
For configuring the slaves on the PROFIBUS, you need the “ibaDPMSi.gsd“ GSD file.
You find this file on the DVD „iba Software & Manuals“ included in delivery in the directory
02_iba_Hardware\ibaBM-DP\02_GSD_Files\01_General\.
Import the GSD file in the “HW Config“ tool under Step 7. In the catalog of the available
modules, you now find the “ibaBM-DPM-S/DP-Monitor“ device under „PROFIBUS DP –
Additional Field Devices – General“.
With this GSD file, the slaves can be freely defined concerning offsets and data types.
The file contains some predefined slot modules for configuring certain signal groups.
“Output“ represents the output signal group (from the master´s perspective). “Input“ is an
input signal group.
The prepared slot modules in the figure below appear in the tree structure in the right-
hand window. Apart from the slot module sets for input and output signals, several pre-
pared modules for using the ibaPDA-Request-S7 option are available. For more infor-
mation, please see the “ibaPDA-Request-S7“ manual.
In the example in the figure below, we have assigned 112 bytes of source data (from
master to slave) to the ibaBM-DP device. These source data are combined by three slot
modules (64 bytes, 32 bytes and 16 bytes).
