Standards and guidelines for data acquisition Overview
Reference-Designation-System – RDS-PP®
State-Event-Cause-System – ZEUS
Globales-Service-Protokoll – GSP
Designation system for components
Unified description of the state, all events and failures
Unified protocol for communication
Reference Designation System for Power
Plants (RDS-PP ®) was developed by VGB
PowerTech e.V. and is based on the basic
principles of international standards, i.e.
IEC 81346 -1 and -2, DIN ISO 16952-1, DIN
EN 61346-1
State-Event-Cause-System (ZEUS), based
on DIN EN 13306 and connected to RDS-
PP
Global Service Protocol (GSP), fix structure

The protocol comprise information as
order information
system information (RDS-PP®)
resources
equipments
materials
service information (ZEUS)
Benefits are
full data entry
complete “CV” of a turbine (Lebenslaufakte)
Service information are unified and utilizable
compatibility of different systems
effort reduction (less paper work)
