Connecting with the Office
Benefits
Current Plant Information always available in Office Environment
Technical departments
Management / Top Management
Utility
Incident Analysis and Plant Optimization away
from the office
Using SPPA-T2000 archive
Expressive and easy to make Reports for
Authority
Internal departments
Using Office Applications like Excel or Access

OPC - Server
Benefits
Open
System-wide operation between automation products of
various manufacturers
Data is only acquired once from field level right up to operational
control level
Use of Microsoft OLE/COM and DCOM technologies
Access to Microsoft-Office under Windows (VBA)
Easy to Use
Same user interface for different components
Performance
C++ interface
Efficient data access through volume operations
Requirement-oriented client - server - communication
Several Clients

Access to SPPA-T2000 data
provides access from Windows PC
to the SPPA-T2000 system
based on standard interface
Server for
SPPA-T2000
Data Access Interface 2.0 (DA 2.0)
Supports all mandatory objects and methods
Custom and Automation Interface available
Cyclic Read
current values of signals,
parameters and
function block output ports
Subscribe for reporting on signal changes
Write to function block input ports
Historical Data Access Interface 1.1 (HDA 1.1)

Custom Interface available and Automation Interface
read data at point in time
read time series data
read processed data (e.g. mean values)
