What is the condition of your DCS system? Find it out with an audit!

SIMATIC System Audit

Maximum productivity and economic efficiency with increasingly complex plants and rising cost pressure - these are the core challenges for SIMATIC automation systems. Matching of products, availability and serviceability are becoming increasingly important. A SIMATIC System Audit provides the essential basis for the conception of service strategies and the efficient implementation of modernization projects.

Transparency of the plant condition and its serviceability

A SIMATIC System Audit basically provides clarity about the current status and serviceability of the SIMATIC automation system.


Even if there are no current problems, a system audit is recommended as a basis for future service strategies, upgrades, or lifecycle service contracts.


The audit provides a detailed insight into the quality of project planning and the current status of a SIMATIC PCS 7 / neo system or a WinCC-based SCADA system with subordinate SIMATIC S7 level.

Modular structure of the SIMATIC System Audit

The modular structure of a SIMATIC system audit enables differentiated assessment of a wide variety of system configurations and platforms: physical and virtual. The basis for all modules is a "Detailed System Check".


Here, the Siemens components are being evaluated and its general serviceability derived. Depending on the module, an "Upgrade Check", a "Conformance Check" or a "PCS neo Readiness Check" follows.


The audit results are documented in a report, and identified problems or deviations from existing standards are clarified.


The report provides specific guidance and recommendations for restoring serviceability and upgrade capability.

The analysis of a SIMATIC PCS 7 system to assess the plant condition serves as a basis for the

  • Decision for system extensions
  • Development of service strategies
  • Increase in general system availability

The analysis of a WinCC-based SCADA system checks and evaluates the components of the system configuration according to the desired audit focus.


Audit Objective:

  • Analysis of the system with identification of potential risks as complete as possible
  • Definition of suitable measures to generally increase system availability or to achieve the target state

The "DCS Upgrade Study" module is a specialized service module for preparing a SIMATIC PCS 7 system upgrade project.


Basic topics in this module are the assessment of serviceability and the current system status based on the service module "Audit DCS/SCADA Status". However, the focus is increasingly placed on upgrade/update capability.


Audit Objective:

  • Analysis of the system with identification of potential risks as complete as possible
  • Detailed preparation of a SIMATIC PCS 7 system upgrade

The Lifecycle Conformance Report as a result of the Conformance Check contains, in particular, statements on contractual aspects that need to be taken into account in preparation of a contract, e.g. measures to restore long-term serviceability or upgradeability. These measures should be implemented before the contract is signed, otherwise it may lead to corresponding exclusions in the contract.


Audit Objective:

  • Preparation of a long-term SIMATIC PCS 7 lifecycle service contract with up to 15 years duration

The "PCS neo Readiness" module focuses exclusively on testing the framework conditions for an evolution of an existing SIMATIC PCS 7 system to SIMATIC PCS neo.


Based on the PCS 7 engineering data, an analysis of used functions and their implementation in the project is carried out, focusing on realization within the SIMATIC PCS neo system.

In addition, all hardware components used in the SIMATIC PCS 7 project are checked for compatibility with SIMATIC PCS neo.


Audit Objective:

  • Evaluation of the framework conditions and necessary measures for the evolution of a SIMATIC PCS 7 project to SIMATIC PCS neo.
