Locating and Licensing SIMATIC PCS 7 SIS Compact Example Unit Templates

Pre-engineered example unit templates for SIMATIC PCS 7 SIS Compact (such as the Gas-Fired Steam Boiler template) are not packaged on standard PCS 7 installation media; they are specialized application examples distributed via Siemens Industry Online Support (SIOS Entry ID 109755219) and regional Siemens Solution Partners. Access requires a registered SIOS account subject to international export control regulations (AL: N, ECCN: EAR99). To utilize these templates, an engineering environment requires SIMATIC PCS 7 SIS Compact software, S7 F Systems V6.2 or higher, and the corresponding Safety Matrix runtime licenses, operating on CPU 410 SIS hardware.

Architecture of SIMATIC PCS 7 SIS Compact

SIMATIC PCS 7 SIS Compact is a dedicated, pre-packaged safety instrumented system (SIS) solution designed for standalone SIL 3 safety applications such as Emergency Shutdown (ESD), Burner Management Systems (BMS), and Fire and Gas (F&G) systems. It utilizes the dedicated CPU 410 SIS controller paired with fail-safe ET 200 distributed I/O (such as ET 200SP HA or ET 200M F-modules).

To accelerate safety project implementation, Siemens provides standardized Unit Templates (such as the 'SIS Compact Unit Template - Gas-Fired Steam Boiler'). These templates incorporate pre-configured CFC safety logic, S7 Safety Matrix cause-and-effect charts, and pre-built WinCC visualization faceplates compliant with IEC 61508 / IEC 61511 and NFPA 85 standards.

Accessing Restricted Unit Templates via SIOS

Users attempting to browse example projects inside SIMATIC Manager often find that the SIS Compact templates are absent after installing the base software. This occurs because:

Restricted Export-Controlled Download: Because functional safety logic can be applied to critical infrastructure and dual-use industrial applications, Siemens subjects safety unit templates to strict export control compliance.
Online Distribution (SIOS Entry ID 109755219): The Gas-Fired Steam Boiler Unit Template must be downloaded from the Siemens Industry Online Support portal. Users must possess a registered login with export approval (Siemens Export Control clearance).
Regional Partner Distribution: In certain regions, access to specialized unit templates requires direct coordination with an authorized Siemens Regional Solution Partner or local Siemens Technical Competence Center.

Functional Comparison: SIS Compact vs Standard PCS 7 Safety

The following table compares SIMATIC PCS 7 SIS Compact with standard full-scale PCS 7 Safety Integrated:

| System Parameter | SIMATIC PCS 7 SIS Compact | Standard PCS 7 Safety Integrated |
|---|---|---|---|
| Target Controller | CPU 410 SIS (Dedicated Safety) | Standard CPU 410-5H or CPU 417-4H |
| Maximum Process Objects | Capped at safety capacity limits (e.g. 500 PO) | Scalable up to 2,600+ POs per controller |
| Safety Standard Compliance | IEC 61508 (SIL 1 to SIL 3), NFPA 85 | IEC 61508 (SIL 1 to SIL 3), NFPA 85/86 |
| Software Packages | S7 F Systems + S7 Safety Matrix (Bundled/Optional) | Modular S7 F Systems RT + Matrix RT Licenses |
| Example Unit Templates | Available via SIOS Entry 109755219 | Distributed via PCS 7 Advanced Process Library DVD |

Software Licensing and Hardware Prerequisites

Deploying the SIS Compact Unit Template requires the following verified software licenses and hardware components:

Hardware: SIMATIC PCS 7 SIS Compact Controller bundle based on CPU 410 SIS (6ES7654-7VA00-0YB0 or equivalent system expansion package).
Engineering License: SIMATIC PCS 7 Engineering System Safety package, including S7 F Systems Engineering (6ES7833-1FC02-0YA5 for V6.2) and SIMATIC S7 Safety Matrix Tool (6ES7833-6AA02-0YA5).
Runtime Licenses: S7 F Systems Runtime License for CPU 410 (6ES7833-1CC00-0YX0) and Safety Matrix Runtime License (6ES7833-6AC02-0YH5).

[!NOTE]
Commercial Accuracy Guardrail: License packages and order numbers (MLFBs) must be verified against current Siemens Catalog ST PCS 7 or through an authorized Siemens distributor quotation. Unit templates are engineering aids and do not replace mandatory safety lifecycle validation (FAT/SAT) required by IEC 61511.

Verification

To verify successful template installation and licensing:

Open the downloaded unit template project (.zip archive) in SIMATIC Manager using File -> Retrieve.
Open the S7 Program and verify that CFC safety charts and Safety Matrix objects open without license errors.
In the Safety Matrix editor, click Compile to verify that the Cause-and-Effect logic generates standard F-System CFC charts.
Check the S7 F-Configuration consistency tool to confirm that safety checksums (CRC) match expected template specifications.

Limitations and Operational Precautions

Mandatory Safety Validation: Pre-engineered unit templates are design baselines. Process safety engineers must re-validate all SIL interlocks, response times, and failure modes to match plant-specific Safety Requirement Specifications (SRS).
Hardware Binding: Templates configured for CPU 410 SIS require hardware adaptation if deployed on standard S7-400H hardware.
Export Clearance Lead Time: Siemens SIOS export approval can take several business days to process for new accounts.

Engineer FAQ

Can the Gas-Fired Steam Boiler template be used on a standard S7-410-5H CPU?

Yes. While engineered specifically for PCS 7 SIS Compact, the CFC logic and Safety Matrix can be migrated into a standard PCS 7 multiproject with S7-410-5H controllers, provided S7 F Systems licenses are present.

Is the S7 Safety Matrix mandatory to run the SIS Compact template?

The template uses Safety Matrix for burner shutdown logic. Without a Safety Matrix engineering license, the matrix charts cannot be edited or compiled.

Why does SIOS prompt for registration when downloading Entry ID 109755219?

Safety-related software and industrial control unit templates are classified under export control regulations and require identity verification before download authorization is granted.

Does PCS 7 SIS Compact support non-safety standard control?

Yes, limited basic process control system (BPCS) functions can run concurrently on CPU 410 SIS up to the configured Process Object limit, but standard PCS 7 controllers are recommended for large-scale BPCS.
