Determining Compatible CEMAT Library Versions for SIMATIC PCS 7 V9.1

For SIMATIC PCS 7 V9.1, the officially released and supported library version is SIMATIC PCS 7 CEMAT V9.1 (along with subsequent maintenance service packs CEMAT V9.1 SP1 and SP2). Legacy versions such as CEMAT V8.x or V7.x cannot be installed on PCS 7 V9.1 due to operating system incompatibility (Windows 10 64-bit architecture) and breaking changes in STEP 7 V5.6 and WinCC V7.5. Installations on PCS 7 V9.1 SP1 or SP2 should deploy the matching CEMAT service pack.

CEMAT and PCS 7 Release Compatibility Matrix

SIMATIC PCS 7 CEMAT (Cement and Minerals Automation Technology) is the specialized process control library designed for mining, cement, and bulk material handling industries. Because CEMAT deeply customizes CFC block structures, WinCC faceplates, and system scripts, its versions are strictly coupled to specific PCS 7 releases.

The compatibility relationship is governed by the following rules:
* PCS 7 V9.1 Base: Requires CEMAT V9.1. Legacy versions (CEMAT V9.0, V8.2, V8.1, V7.x) are strictly unsupported on PCS 7 V9.1.
* PCS 7 V9.1 SP1: Requires CEMAT V9.1 SP1.
* PCS 7 V9.1 SP2: Requires CEMAT V9.1 SP2.
* Operating System Alignment: CEMAT V9.1 runs on 64-bit operating systems:
* Windows 10 Enterprise LTSC (2019 / 2021).
* Windows Server 2019 / 2022.
* Underlying SCADA and Engineering: CEMAT V9.1 incorporates native support for WinCC V7.5 SP2, S7-SCL V5.6, and the S7-410 Process Automation controller family.

Attempting to force an older CEMAT installation (such as CEMAT V9.0 SP1 or V8.2) onto PCS 7 V9.1 fails during setup or causes severe script compilation crashes in WinCC Graphics Designer.

Step-by-Step Installation and Library Deployment Workflow

Follow this procedure to install and integrate CEMAT V9.1 on a PCS 7 V9.1 Engineering Station.

Prerequisites

SIMATIC PCS 7 V9.1 (or V9.1 SP1/SP2) already installed and verified on the computer.
Official installation media for SIMATIC PCS 7 CEMAT V9.1 (DVD or ISO image).
CEMAT engineering and runtime license keys transferred via Automation License Manager (ALM).

Step 1: Pre-Installation Check

Ensure all SIMATIC applications (SIMATIC Manager, CFC, WinCC Explorer) are closed.
Confirm the exact PCS 7 version via SIMATIC Manager -> Help -> About.
Verify that your CEMAT installation media service pack precisely matches your installed PCS 7 service pack level.

Step 2: Execute CEMAT Setup

Launch Setup.exe from the CEMAT V9.1 installation media with administrative privileges.
Select the installation scope based on station role:
* Engineering Station (ES): Install CEMAT Engineering, AS blocks, WinCC Faceplates, and Documentation.
* OS Server / Single Station: Install CEMAT OS Server components.
* OS Client: Install CEMAT OS Client faceplates and runtime files.
Follow the wizard prompts and complete the setup. Reboot the station when prompted.

Step 3: Integrate CEMAT Master Library into the Project

Open SIMATIC Manager and load your plant Multiproject.
Open File -> Open -> Libraries and select the CEMAT V9.1 Library.
Copy the required technological blocks (C_DRV_1D, C_DRV_2D, C_DAMPER, C_ANNUNC, C_MEASUR) into your project's Master Data Library.
In SIMATIC Manager, select Options -> Block Types and update all chart instances across your automation programs.

Step 4: Run CEMAT OS Project Configuration

Open WinCC Explorer on the OS project.
Run the CEMAT Update / Project Configuration Tool to copy CEMAT-specific picture files (@PG_C_*.pdl), bitmaps, and C-scripts into the project directory.
Execute the OS Project Editor to ensure standard picture windows and resolution layouts are aligned.

Verification

In SIMATIC Manager, check Help -> About -> Installed Software. Confirm that SIMATIC PCS 7 CEMAT appears with version V9.1.
In CFC, open a chart containing a CEMAT block (e.g., C_DRV_1D) and confirm clean compilation with 0 syntax errors.
In WinCC Graphics Designer, open a CEMAT block icon. Verify that clicking the icon opens the corresponding CEMAT faceplate without missing script errors.
Open Automation License Manager and verify that the CEMAT Engineering and CEMAT Runtime licenses show status In use / Valid.

Limitations and Operational Precautions

Standard APL Interoperability: While CEMAT V9.1 can coexist in the same project with standard Advanced Process Library (APL) blocks, individual technological loops should strictly use either pure CEMAT or pure APL blocks to maintain uniform operator faceplates and interlocking logic.
Firmware Compatibility: Verify that connected S7-400 or S7-410 controllers have firmware levels supported by CEMAT V9.1 (S7-410 firmware V8.2+ recommended).
Project Migration: Upgrading an existing plant from CEMAT V8.x to V9.1 requires running the official CEMAT migration tool; block structures cannot be overwritten directly without schema migration.

Engineer FAQ

Can CEMAT V9.0 SP1 be installed on PCS 7 V9.1?
No. CEMAT V9.0 SP1 was released for PCS 7 V9.0 and is not compatible with PCS 7 V9.1. You must use CEMAT V9.1.
Is CEMAT a free add-on or a licensed product?
CEMAT is a commercial Siemens industry solution requiring specific software licenses for engineering and each active runtime station.
What is the difference between Minerals (C_MIN) and Cement standards in CEMAT?
CEMAT supports multiple international standards (Holcim, Heidelberg, Dyckerhoff, standard Cement, and Mining/Minerals). The selected standard dictates block interfaces, interlocking philosophies, and faceplate layouts.
Does CEMAT require special hardware?
No special hardware is required; CEMAT runs on standard SIMATIC S7-400 and S7-410 controllers and standard industrial PC hardware.
Where can I verify official compatibility between PCS 7 and CEMAT?
Use the online Siemens Compatibility Tool (SIOS Entry ID 64847781) to verify specific software combination matrices.
