Management Information System (MIS) Architecture, System Setup, and Reporting in SIMATIC PCS 7

In SIMATIC PCS 7, implementing a Management Information System (MIS) to provide plant managers, process engineers, and corporate executives with long-term KPI reporting, batch production tracking, energy monitoring, and asset analytics requires a layered enterprise software architecture. The standard system setup combines (1) SIMATIC Process Historian (PH) for centralized high-performance SQL-based long-term process archiving, (2) SIMATIC Information Server (IS) for web-based automated report generation (Excel/PDF) and dashboard delivery, (3) WinCC DataMonitor or OpenPCS 7 for real-time web visualization and OPC UA enterprise connectivity, and optionally (4) CEMAT MIS for specialized mining and cement plant production analysis.

Role and Business Purpose of an MIS in Industrial Control

A process control system (DCS) excels at millisecond-level closed-loop regulation and real-time operator intervention. However, plant managers and operational directors require aggregated, contextualized business intelligence: Overall Equipment Effectiveness (OEE), specific energy consumption per ton of product, shift production yields, and environmental emissions compliance.

A Management Information System (MIS) acts as the bridge between the industrial OT layer (PCS 7 OS Servers) and the corporate IT layer (ERP, MES, BI tools). It extracts raw process values, alarms, and batch logs, processes them into meaningful metrics, and presents them in accessible corporate formats without impacting control system safety or cycle times.

Core Architectural Layers of a PCS 7 Management Information System

A robust PCS 7 MIS architecture is divided into three distinct operational tiers:

Data Acquisition Tier (OT Layer): Redundant WinCC OS Servers and SIMATIC BATCH servers collect real-time sensor measurements and alarms from the AS controllers.
Central Archiving Tier (Middleware Layer): The SIMATIC Process Historian (PH) acts as the centralized enterprise repository. It runs Microsoft SQL Server on dedicated server hardware in the control room or DMZ, automatically ingesting historical tag logging and alarm logging data via the PH-Ready service.
Information Delivery Tier (IT/Business Layer): The SIMATIC Information Server (IS) and WinCC DataMonitor host web applications. Users across the corporate office network query trends, generate scheduled shift reports, and view executive dashboards through web browsers without installing engineering software.

Deploying SIMATIC Process Historian and Information Server

To establish the foundation of the MIS:

Server Hardware: Deploy dedicated enterprise server hardware (e.g., dual quad-core processors, 64 GB RAM, RAID 10 SSD storage) for the Process Historian.
Database Ingestion: Install Process Historian. In the PH Management Console, configure the WinCC OS Servers as active Data Sources. Process values stream continuously over the Terminal Bus.
Information Server Deployment: Install Information Server (either on the PH hardware or on an independent web server). IS connects to the PH database via internal SQL reporting services, exposing pre-built report templates for alarms, process values, and batch records.

Web-Based Reporting, Dashboards, and Microsoft Office Integration

The primary user-facing interfaces of the PCS 7 MIS include:

Automated Report Distribution: Configure scheduled reporting jobs in Information Server. The system automatically compiles daily production summaries or emission logs at midnight and dispatches them via email as formatted PDF or Excel attachments to plant management.
Microsoft Excel Add-In: Business analysts can utilize the official Information Server Excel Add-in to pull historical process tags directly into corporate spreadsheets for financial modeling and regression analysis.
CEMAT MIS Option: In cement and mineral plants, the specialized CEMAT MIS package adds pre-engineered reports for kiln production hours, raw mill energy consumption, and conveyor fault frequency.

Hardware and Software Procurement Schedule for PCS 7 MIS

The following schedule outlines the primary software packages and licenses required to establish an enterprise PCS 7 MIS:

| Software Component | Siemens Order Number (MLFB) | License Scope and Purpose |
|---|---|---|---|
| SIMATIC Process Historian Basic Package | 6ES7652-7AX28-0YB0 | Central SQL long-term archive server license |
| SIMATIC Information Server Basic Package | 6ES7652-7BX28-0YB0 | Web reporting engine and report template generator |
| Information Server Client Access Licenses | 6ES7652-7BX28-2YB0 | 1, 5, or 10 concurrent web client access licenses (CAL) |
| OpenPCS 7 Gateway (Optional) | 6ES7658-0HX28-2YB0 | Exposes real-time and historical data via OPC UA DA/HDA |
| WinCC DataMonitor (Alternative Web View) | 6AV6371-1DN07-4AX0 | Web-based process graphics and trend viewing |

Commercial Accuracy Disclaimer: Software order numbers (MLFBs), package structures, and hardware capacity prerequisites vary across PCS 7 versions and hardware platforms. System integrators must confirm exact software entitlements and licensing requirements against the official Siemens Catalog CA 01 and obtain an authorized Siemens distributor quotation prior to purchasing.

Verification

Verify the Management Information System functionality:
1. On a corporate office laptop connected to the business network, open a web browser and navigate to the Information Server URL (e.g., https://infosrv01/InformationServer).
2. Log in using Active Directory credentials; verify that the dashboard renders correctly.
3. Select the 'Standard Process Value Trend Report'; select an analog tag, specify a 24-hour time range, and click 'Execute Report'.
4. Verify that the report generates within 5 seconds, displaying statistical summaries (Min, Max, Mean) and a clean graphical trend line.
5. Export the report to PDF; confirm that formatting and corporate headers are preserved.

Limitations and Operational Precautions

Never connect corporate office clients directly to the mission-critical PCS 7 Terminal Bus. The Process Historian and Information Server must be placed in a Demilitarized Zone (DMZ) with a dedicated perimeter firewall. Only HTTP/HTTPS (ports 80/443) should be permitted from the corporate network to the Information Server, completely isolating the AS controllers and OS runtime servers from corporate malware risks.

Engineer FAQ

Does an MIS system come included with CEMAT?

No. While CEMAT provides specialized mining and cement report templates and data collection blocks, the underlying Process Historian and Information Server software packages require separate purchasing and licensing.

What is the difference between Information Server and DataMonitor?

Information Server is an advanced reporting engine designed for automated PDF/Excel reports, long-term archiving, and regulatory auditing. WinCC DataMonitor is focused on displaying live WinCC process screens and trends inside a web browser.

Can external ERP systems like SAP query the Process Historian database directly?

Siemens strictly advises against querying the underlying SQL database tables directly with raw SQL scripts. External ERP/MES systems should interface via the official OpenPCS 7 OPC UA server or Information Server REST APIs.
