Introduction
When commissioning a Profibus DP network, the devices on the Profibus DP must
be parameterized and configured using the programming software at the controls
(Profibus configurator).
The programming software first reads the GSD file (GeneralStationData) of the
individual actuators. The GSD file contains information about the device properties
needed by the master.
Afterwards, the user can configure and parameterize the device at the Profibus DP
for the programming software of the process control system.
This information is then stored in the controls (DP master) and sent to the actuators
(DP slaves) each time cyclic communication is started.
The process representation input and output bytes are used to control the actuator
and to supply the feedback signals. If a configuration with consistent data is selected,
certain PLCs require special functional elements for the control of the Profibus DP
slaves.
Certification
AUMA actuators with Profibus DP are certified by the Profibus user organisation
(PNO).
ID number
Each DP slave and each DP master have individual ID numbers. The ID number is
required for the DP master to identify the type of device connected without signification
protocol overhead. The master compares the ID numbers of the connected DP
devices to the ID number in the specified configuration data. The process data transfer
will only be started if the correct device types with the correct station addresses were
connected to the bus. This ensures a high security against configuration errors.
The PNO manages the ID numbers together with the device master data (GSD).
AUMA actuators with actuator controls AC 01.2 are listed under the following ID
numbers at the PNO:
●
ID number of the standard version: 0x0C4F with functions for:
-
Single channel Profibus DP interface (not redundant)
-
Redundant Profibus DP interface according to AUMA redundancy (I or II)
-
Optional Profibus DP V1 services
●
ID number of the extended version: 0x0CBD with functions for:
-
Redundant Profibus DP interface according to Profibus DP-V2 redundancy
-
Time stamp and alarms according to Profibus DP-V2
-
Optional Profibus DP V1 services
Device Master Data
(GSD)
For Profibus DP, the performance features of the devices are documented by the
manufacturer and made available to the users as device data sheet and device
master data. Structure, contents and coding of the device master data (GSD) are
standardised. They enable comfortable configuration of any DP slaves with
configuration devices by different manufacturers.
For AUMA actuators with AC 01.2 controls, the following GSD files are available:
●
Standard version: AUMA0C4F.GSD with functions for:
-
Single channel Profibus DP interface (not redundant)
-
Redundant Profibus DP interface according to AUMA redundancy
-
Optional Profibus DP V1 services
●
Optional version: AUMA0CBD.GSD with functions for:
-
Redundant Profibus DP interface according to Profibus DP-V2 redundancy
-
Time stamp and alarms according to Profibus DP-V2
-
Optional Profibus DP V1 services
