Intel 8th and 9th Generation Processor Compatibility with PCS 7 V9.0 SP1 and SIMATIC IPC Sizing

In SIMATIC PCS 7 V9.0 SP1, 8th and 9th Generation Intel Core i7 processors (Coffee Lake / Coffee Lake Refresh) are fully compatible at the hardware architecture level. However, operational compatibility is strictly governed by the host operating system: Intel 8th and 9th Generation processors DO NOT support Windows 7 (due to lack of chipset, USB, and ACPI drivers). Therefore, when utilizing 8th/9th Gen Core i7 CPUs, PCS 7 V9.0 SP1 MUST be installed on a 64-bit compatible modern operating system: Windows 10 Enterprise 2015 LTSB (64-Bit) or Windows Server 2016 Standard Edition (64-Bit). Siemens strongly recommends procuring factory-certified SIMATIC Industrial PCs (such as IPC 547G, IPC 647E, IPC 847E) with pre-installed operating systems and PCS 7 software images.

Executive Summary

When specifying new computer hardware for SIMATIC PCS 7 V9.0 SP1 engineering and operator stations, system integrators frequently evaluate modern commercial or industrial workstations powered by 8th and 9th Generation Intel Core i7 processors. While raw CPU instruction sets are fully capable of executing PCS 7, severe commissioning obstacles arise regarding operating system driver support and hardware certification. Attempting to install legacy Windows 7 on 8th/9th Generation hardware fails, leading to unbootable systems or disabled peripherals. This guide defines the processor and OS compatibility matrix for PCS 7 V9.0 SP1 and details the advantages of standardized SIMATIC IPC platforms.

Architecture and Fundamental Mechanics

The execution environment of SIMATIC PCS 7 relies on a synchronized stack comprising hardware microarchitecture, chipsets, operating system kernels, and Siemens automation drivers:
1. Processor Microarchitecture Compatibility:
- SIMATIC PCS 7 software engines (STEP 7, CFC, SFC, WinCC, SQL Server) operate as standard x86/x64 applications. They impose no proprietary CPU instruction limits; Intel Core i7 8th Gen (e.g., i7-8700) and 9th Gen (e.g., i7-9700) provide exceptional multi-core performance for parallel CFC compilation and WinCC graphic caching.
2. Operating System and Chipset Driver Constraints:
- Intel 300-series chipsets (supporting 8th/9th Gen CPUs) dropped hardware driver support for Microsoft Windows 7. Critical peripheral controllers (xHCI USB 3.1, integrated UHD Graphics, NVMe storage controllers) lack functional Windows 7 drivers.
- SIMATIC PCS 7 V9.0 SP1 officially supports four 64-bit operating systems:
* Windows 7 Professional / Ultimate / Enterprise SP1 (64-Bit) -> Limited to Intel 6th Gen (Skylake) and older hardware.
* Windows 10 Enterprise 2015 LTSB (64-Bit) -> Certified for 8th/9th Gen Intel platforms.
* Windows Server 2012 R2 Standard Edition (64-Bit) -> Restricted chipset support on newer hardware.
* Windows Server 2016 Standard Edition (64-Bit) -> Certified for 8th/9th Gen Intel server platforms.
3. Pre-Installed SIMATIC IPC Advantage:
- Siemens SIMATIC IPCs (IPC 547G, IPC 647E, IPC 847E) provide certified industrial motherboards, long-term component availability (5+ years active, 5 years spare parts), redundant hot-swap power supplies, and pre-installed Windows operating systems configured to Siemens industrial standards. They feature pre-installed PCS 7 software baselines, requiring engineers only to configure computer names and transfer licenses.

Step-by-Step Implementation Procedure

Verify Hardware Specification Against Operating System Requirements:
a. If selecting 8th or 9th Generation Intel Core i7 processors, mandate that the host operating system is either Windows 10 Enterprise 2015 LTSB (64-Bit) or Windows Server 2016 Standard (64-Bit).
b. Do NOT attempt to install Windows 7 on 8th/9th Generation motherboards.
c. Ensure a minimum of 16 GB RAM (32 GB recommended for ES and OS Servers) and high-endurance enterprise SSDs (NVMe or SATA).
Configure Communications Processors and Peripheral Slots:
a. Verify that the PC motherboard features dedicated PCIe slots for communications processors (such as the CP 1623 for Plant Bus connection).
b. Confirm that CP 1623 drivers included in SIMATIC NET V14 SP1 (or PCS 7 V9.0 SP1 bundled software) support the installed Windows OS build.
Evaluate SIMATIC IPC Configurator Options:
a. Access the Siemens Industry Mall SIMATIC IPC Configurator.
b. Select the industrial form factor: IPC 547G (19-inch 4U rack, cost-effective), IPC 647E (19-inch 2U rack, compact rugged), or IPC 847E (19-inch 4U rack, maximum expandability).
c. Configure the processor: select 8th/9th Gen Intel Core i7 or Xeon.
d. Select the operating system: choose Windows 10 Enterprise LTSB or Windows Server 2016 pre-installed.
e. Select the pre-installed software image: 'SIMATIC PCS 7 Engineering Station' or 'SIMATIC PCS 7 OS Server/Single Station'.
Commission Station in PCS 7 Multiproject:
a. Upon delivery of the IPC, power on the station and complete the initial Windows Out-of-Box Experience (OOBE).
b. Assign the exact Windows computer name configured in SIMATIC Manager HW Config.
c. Configure static IP addresses for the Plant Bus and Terminal Bus network cards.
d. Run the Siemens Security Controller to verify firewall rules.
e. Transfer software licenses using Automation License Manager (ALM).

Verification

Open Windows System Information (msinfo32): confirm the processor is identified as an Intel Core i7 8th/9th Gen and the operating system is Windows 10 Enterprise LTSB or Windows Server 2016.
Open Device Manager: verify that all chipset, storage, and graphics drivers are installed cleanly without yellow exclamation marks.
Open SIMATIC Manager: execute a test CFC compilation and verify that multi-threading compiles charts rapidly without hardware exceptions.
Launch WinCC Explorer: activate runtime and confirm graphics render smoothly with low CPU utilization.

Limitations and Operational Precautions

Commercial off-the-shelf (COTS) desktop office PCs lack industrial shock/vibration ratings, lack long-term spare part availability, and frequently change motherboard revisions without notice, causing hardware driver incompatibilities with SIMATIC NET. PCS 7 V9.0 SP1 does not support commercial Windows 10 Home, Pro, or semi-annual channel (SAC) editions; only Long-Term Servicing Channel (LTSB/LTSC) editions are supported. Hardware procurement and IPC configurations should be confirmed with an authorized Siemens distributor or the Siemens Industry Mall.

Engineer FAQ

Can I run Windows 7 on an 8th Generation Intel Core i7 PC?

No. Intel and Microsoft dropped Windows 7 driver support for 8th and 9th Generation chipsets; attempting to install Windows 7 results in non-functional USB and system devices.

What Windows 10 edition is supported by PCS 7 V9.0 SP1?

Windows 10 Enterprise 2015 LTSB (64-Bit). Standard commercial Windows 10 Pro or SAC editions are not supported.

What is the advantage of purchasing a Siemens IPC over a commercial PC?

SIMATIC IPCs offer guaranteed hardware compatibility, long-term industrial availability, certified shock/vibration tolerance, and pre-installed PCS 7 software images.

Do 8th/9th Gen processors require a specific version of SIMATIC NET?

Yes. SIMATIC NET PC Software V14 SP1 (included with PCS 7 V9.0 SP1) is required to support modern network drivers under Windows 10 LTSB and Server 2016.
