Host System Integration
The configuration of the device in a PROFIBUS network requires a GSD file. The file describes
the details of communication capabilities and structures of cyclic data. For the *D0-MIO-
Ex12.PA, different GSD files are available to support different modes of operation.
The manufacturer-specific GSD files for MIO mode of operation offer the full functionality of the
devices. The GSD file is available on the Internet under www.pepperl-fuchs.com.
The profile-specific GSD files are defined by the PROFIBUS PA profile 3.02. The GSD files
offer a limited, standardized functionality that guarantees interoperability between devices of
different manufacturers. Profile-specific GSD files are available on the Internet under
www.pepperl-fuchs.com.
The FD0-VC-Ex4.PA and FD0-BI-Ex12.PA GSD files are used if in an existing installation of a
device has to be replaced. The GSD files of preceeding Fuchs process interfaces are
available on the Internet under www.pepperl-fuchs.com.
4.2
Configuration of Cyclic Communication
Prerequisite: The GSD file is installed in your process system. For more information, see
chapter 4.1.
During cyclic data exchange, "user data" is exchanged in regular intervals between the master
and the slave or bus, e. g., between a process control system and a field device. User data
includes, e. g., measurement values, limit position feedback, and output data, etc. The bus
cycle time depends on the number of nodes and the amount of data that is transmitted.
The cyclic data is represented in so called
“
modules
”
which are mapped to slots. For each
hardware channel a module can be selected. The module data consists of a combination of
input and output data of different variables. Modules of the different operation modes are not
allowed to be mixed other than stated below. The supported types of modules are described in
the specific GSD files.
Module types for the valve coupler mode and the FD0-VC-Ex4.PA compatibility mode In the
valve coupler mode the following variables for cyclic communication are available:
■
Empty module: Used if a channel is not used for cyclic communication.
■
OUT_D: Input value and status of position feedback monitor.
■
SP_D: Specified setpoint value of valve position in the "Auto" mode.
■
RB_D: Feedback of valve position and the states of the position feedback inputs and their
line fault condition.
■
CB_D: Detailed status, alarm, and fault condition of the valve.
■
RIN_D: Specified setpoint value of host in the "RCas" mode of operation.
■
ROUT_D: Setpoint value feedback to host in the "RCas"mode of operation.
