Resolving Missing CPU 416-5H in SIMATIC PCS 7 HW Config Hardware Catalog Profiles

Resolving Missing CPU 416-5H in SIMATIC PCS 7 HW Config Hardware Catalog Profiles

The absence of CPU 416-5H (6ES7416-5HT06-0AB0) in the SIMATIC PCS 7 HW Config hardware catalog occurs because the catalog display filter defaults to the 'PCS 7 Profile' (e.g., PCS7_V90), which displays only controller models officially released and bundled for PCS 7 systems. While CPU 410-5H and CPU 417-5H are native PCS 7 controllers, the CPU 416-5H is classified as a classic SIMATIC S7-400H hardware component. Switching the catalog profile dropdown from 'PCS7_Vxx' to 'Standard' makes the CPU 416-5H immediately visible under SIMATIC 400 -> CPU 400 -> CPU 400-H. Engineers must verify module driver compatibility before deploying non-standard CPUs in PCS 7 projects.

Hardware Catalog Profiles: PCS 7 vs Standard

In SIMATIC STEP 7 and PCS 7 HW Config, the Hardware Catalog uses configurable Profiles to filter visible modules. This filtering prevents engineers from inadvertently inserting industrial automation modules that lack certified PCS 7 driver blocks or faceplates.

When PCS 7 is installed, the catalog profile is automatically locked to the active system version (e.g., PCS7_V82 or PCS7_V90). This profile presents a curated subset consisting of the CPU 410-5H, high-end S7-400H CPUs (417-5H), ET 200M/SP stations, and certified SCALANCE switches.

Why CPU 416-5H Is Hidden in Standard PCS 7 Profiles

The table below contrasts controller positioning across hardware catalog profiles:

Procedure to Reveal and Configure CPU 416-5H

To make the CPU 416-5H selectable within HW Config:

Step 1: Switch the Hardware Catalog Profile

1. Open HW Config in SIMATIC Manager.
2. Locate the Profile dropdown menu located in the top-right corner of the Hardware Catalog window.
3. By default, it indicates PCS7_V90 or PCS7_V82.
4. Click the dropdown and select Standard.

Step 2: Browse to CPU 416-5H

1. In the catalog tree, expand SIMATIC 400 -> CPU 400 -> CPU 400-H.
2. Locate CPU 416-5H (6ES7416-5HT06-0AB0).
3. Drag and drop the CPU into Rack 0 (Slot 3 or 4) of your UR2-H subrack.

Step 3: Install Hardware Support Packages (HSP) if Required

If the specific firmware revision (e.g., Firmware V6.0) is missing even in the Standard profile:
- Select Options -> Install Hardware Updates.
- Download and install the latest S7-400H Hardware Support Packages (HSP) from Siemens Industry Online Support.

Verification

To verify that the CPU 416-5H is properly integrated:

1. Confirm that Rack 0 and Rack 1 in HW Config host the CPU 416-5H with synchronization submodules (FO sync modules).
2. Execute Station -> Save and Compile: verify that HW Config compiles without bus or rack addressing errors.
3. In the CFC Editor, execute Options -> Block Types... -> verify that module driver generation blocks (OB_DIAG1) are available.
4. Compile CFC with 'Generate module drivers' checked: confirm compilation concludes with zero diagnostic structure faults.
5. Download configuration to the CPU: verify that both redundant CPU 416-5H controllers enter synchronized RUN-Redundant mode.

Limitations and Operational Precautions

Operational boundaries when using classic S7-400 CPUs in PCS 7:

• Module Driver Generation: While CPU 416-5H is supported by classic STEP 7 driver generators, verify that all I/O modules connected to it belong to the PCS 7 Released Modules list to ensure APL channel drivers compile correctly.
• Firmware Downgrade Simulation: If a physical CPU has newer firmware than available in the catalog, configure the latest available firmware version in HW Config; the CPU will operate in backwards-compatible mode.
• Upgrade Recommendation: For new PCS 7 projects, always select the unified CPU 410-5H, which provides superior performance, online Process Object expansion, and native PROFINET system redundancy.

Engineer FAQ

Why was CPU 416-5H missing from the hardware catalog in PCS 7?

The catalog was set to the 'PCS 7 Profile', which hides classic S7-400 CPUs that are not part of the standard PCS 7 bundled delivery release.

How do I switch the catalog profile in HW Config?

Select the dropdown menu labeled 'Profile' in the top-right corner of the Hardware Catalog window and change it to 'Standard'.

Will PCS 7 module drivers generate properly for CPU 416-5H?

Yes, provided the connected I/O stations (ET 200M/SP) and communication processors are listed in the PCS 7 Released Modules catalog.

Can a CPU 416-5H run the PCS 7 Advanced Process Library (APL)?

Yes, CPU 416-5H supports the PCS 7 APL, although memory limits (work memory) must be carefully monitored compared to the CPU 410-5H.
