1 CONFIGURATION OF SRD991 / SRD960 VIA PROFIBUS
1.1 General
Information
The Profibus communication interface offers multiple possibilities: Cyclic communication with Profibus
master Class 1 and acyclic communication for configuration and parameterization with Profibus
master Class 1 and Profibus master Class 2.
How to operate the Profibus master has to be taken from the according master instruction.
1.2 Initial Setup via PROFIBUS
Before beginning the initial setup, the positioner should be correctly mounted and electrically ready for
operation. The safety regulations must be observed, as described in MI EVE 0105 D-(en)
Chapter 13.
The positioner is preset with default parameters by the manufacturer, and instrument-specific data are
permanently stored. The internal temperature sensor, the position sensor angle and pressure sensors
(if applicable) are calibrated.
During the first commissioning the bus address and application-specific data must be entered. If no
entry is made, the default parameters are retained.
1.3 Setting of Bus address
According PROFIBUS-PA Profile 3.0 the default bus address is 126. Since this address isnt allowed
for cyclic communication, it is required to change this address at the first commissioning. This can be
done via the local push buttons at the device or with the Profibus service DDLM_SET_SLAVE_ADD.
Setting of the address via local push buttons is described at MI EVE0105 D-(en).
1.4 Application specific Parameter
At first commissioning at least the actuator system respectively the mounting side has to be configured
before performing an autostart. This can be done via the local push buttons at the device or via the
Parameter POSITION_LINEARIZATION. How to set it via the local push buttons at menue 1 is
described at MI EVE0105 P-(en), Chapter. 8.2. The default value is Linear actuator, left-hand
mounting.
Autostart or Short-autostart can be initiated as well via the local push buttons at the device or via
communication (Parameter SELF_CALIB_CMD). How to do it via local push buttons is described in MI
EVE0105 D-(en). 4

2 CYCLIC COMMUNICATION WITH MASTER CLASS 1
2.1 GSD-File
Configuration and Parameterization of the PROFIBUS itself and the PROFIBUS Master Class 1 will be
done normally by using the GSD-File. The GSD-Files are named FOX_D991.GSD for SRD991 and
FOX_D960.GSD for SRD960. Both are available via Internet at
http://www.profibus.com
or
http://www.foxboro-eckardt.com
. In this connection the Identification numbers are D991 respectively
D960.
In addition to these GSD-Files offered by Foxboro Eckardt the SRD991 or SRD960 can operate also
with the GSD-File defined by Profile 3.0 for actuators. The name of this GSD-File is PA139710.GSD
and is available via Internet at
http://www.profibus.com
. Here the Identification number is 9710.
Within the GSD-File the (timing-) parameters relevant for the communication itself and the different
possibilities of the cyclic date exchange is described.
2.2 Cyclic Data Exchange
For the cyclic data exchange the SRD991 or SRD960 offers 7 possibilites, which are described within
the GSD-File. One of these possibilities has to be selected. Within Foxboro Eckardts GSD-Files
FOX_D991.GSD or FOX_D960.GSD these possibilities are listed in the so-called extended identifier
format. In addition the Module SP is available in the so-called normal identifier format. The other
Modules are described as a comment in the normal identifier format only for information. If necessary
the comment signs can be removed.
2.2.1 Module SP
Normal format:
Module Nr. 1 SP (short) 0xA4
Extended format:
Module Nr. 2 SP 0x82,0x84,0x08,0x05
With this Module only the setpoint SP will be transmitted to the positioner. There is no data
transmission from the positioner back to the master. The setpoint SP will be used by the positioner as
the desired setpoint in mode AUTO.
