Resolving Missing CPU 410E in HW Config Catalog and Engineering Station Requirements

In SIMATIC PCS 7, the CPU 410E (6ES7410-5HM08-0AB0) controller missing from the STEP 7 HW Config catalog on a Field PG or secondary Engineering Station is caused by an outdated Hardware Support Package (HSP), incompatible catalog profile filters, or incorrect rack selection. CPU 410E requires PCS 7 V9.0 or higher with HSP 267 installed. Furthermore, the HW Config catalog profile must be set to 'PCS 7 V9.0' or 'Standard' rather than legacy PCS 7 profiles. In HW Config, CPU 410E cannot be placed in a redundant 'UR2-H' rack; it is an entry-level single-station controller with fixed 200 Process Objects and must be placed in a standard UR1 or UR2 rack. Validate order numbers and hardware options with an authorized Siemens distributor or the Siemens Industry Mall.

Executive Summary

When commissioning entry-level or package unit process control systems with the SIMATIC PCS 7 CPU 410E (Entry), automation engineers frequently find that while the primary combined OS/ES station displays the controller in the hardware catalog, secondary Field PGs or newly deployed engineering laptops fail to list the CPU 410E. This issue prevents offline hardware modifications and logic troubleshooting. This guide details the software baseline requirements, Hardware Support Package (HSP) installation procedures, catalog profile configurations, and rack placement constraints governing the CPU 410E.

Architecture and Fundamental Mechanics

The hardware integration architecture of the CPU 410E encompasses specific software and configuration boundaries:
1. Hardware Identity and Purpose:
- The CPU 410E Process Automation (6ES7410-5HM08-0AB0) is the entry-level variant of the AS 410 platform, designed for small-scale applications, skid units, and package plants.
- Unlike the CPU 410-5H, the CPU 410E is permanently capped at a maximum of 200 Process Objects (POs) and does not support redundant controller (H-system) configurations.
2. Software Prerequisites and HSP Integration:
- CPU 410E was introduced with SIMATIC PCS 7 V9.0.
- It requires STEP 7 V5.6 or higher and Hardware Support Package HSP 267 (or cumulative PCS 7 hardware update packages). If a Field PG is running an earlier version or lacks HSP 267, the catalog XML descriptor for 6ES7410-5HM08-0AB0 is absent.
3. HW Config Catalog Profile Filtering:
- HW Config uses Catalog Profiles (e.g., 'Standard', 'PCS 7 V8.2', 'PCS 7 V9.0'). If the engineer's PG is filtered to an older profile, newer hardware modules are hidden from view.
4. Rack Placement Rules:
- The CPU 410E firmware enforces single-station architecture. Attempting to drag the CPU 410E into a segmented redundant rack (such as UR2-H) will be blocked by HW Config validation rules.

Step-by-Step Implementation Procedure

Verify Engineering Station Operating Software Baseline:
a. On the Field PG, open SIMATIC Manager and select Help -> About -> Installed Software.
b. Confirm that the installed software version is SIMATIC PCS 7 V9.0 SP1 or higher (with STEP 7 V5.6 or higher).
c. If the PG has PCS 7 V8.x installed, CPU 410E cannot be configured; the PG software baseline must be upgraded.
Download and Install Hardware Support Package (HSP):
a. Open STEP 7 HW Config on the PG.
b. Select Options -> Install Hardware Updates from the main menu.
c. Choose 'Download from Internet' (or browse to a locally extracted PCS 7 Hardware Update container).
d. Locate HSP 0267 (CPU 410E / AS 410) in the update list, select it, and click 'Download'.
e. Close all open HW Config windows and execute 'Install' to update the module catalog database.
Switch HW Config Catalog Profile:
a. Open HW Config for any station.
b. In the right-hand Catalog pane, locate the 'Profile' drop-down list at the top.
c. Switch the profile from any customized or legacy profile to Standard or PCS 7 V9.0.
d. Confirm that the catalog refreshes.
Select Compatible Physical Rack in HW Config:
a. Navigate in the catalog to SIMATIC 400 -> RACKS 400.
b. Select a standard universal rack: UR1 (18 slots) or UR2 (9 slots).
c. Do not select UR2-H (redundant split rack), as CPU 410E does not support H-redundancy.
Insert and Configure CPU 410E:
a. Place the power supply module (e.g., PS 407 10A) in Slot 1.
b. Navigate to SIMATIC 400 -> CPU 400 -> CPU 410 -> CPU 410E -> 6ES7410-5HM08-0AB0.
c. Drag and drop the CPU into Slot 3.
d. Assign Industrial Ethernet / PROFINET IP parameters and execute Station -> Save and Compile.

Verification

In HW Config catalog tree, browse to SIMATIC 400 -> CPU 400 -> CPU 410 -> CPU 410E: verify the module 6ES7410-5HM08-0AB0 appears with Firmware V8.2.
In HW Config station layout: verify the CPU places into Slot 3 of a UR2 rack without placement conflict dialogs.
Execute Station -> Save and Compile: confirm compilation completes with 0 errors.

Limitations and Operational Precautions

CPU 410E cannot be expanded beyond 200 Process Objects and cannot be configured in an S7-400H redundant topology. Applications requiring high-availability redundancy or more than 200 POs must use CPU 410-5H.

Engineer FAQ

What is the maximum Process Object capacity of CPU 410E?

CPU 410E is permanently capped at a maximum of 200 Process Objects.

Can CPU 410E be used in an S7-400H redundant configuration?

No. CPU 410E is strictly a single-station controller and cannot be paired for H-redundancy.

Which PCS 7 version first introduced CPU 410E support?

SIMATIC PCS 7 V9.0 introduced native support for CPU 410E.

Why does CPU 410E not show up in the hardware catalog after installing HSPs?

The catalog profile may be filtered to an older version profile. Switch the catalog profile dropdown to 'Standard' or 'PCS 7 V9.0'.

What rack types can house a CPU 410E?

Standard universal racks such as UR1 or UR2. Redundant split racks like UR2-H are not supported for CPU 410E.
