Resolve a CPU 410-5H License Error for Redundant PROFINET I/O

For a CPU 410-5H system using redundant PROFINET R1 subnets, Siemens identifies the CPU 410 Expansion Pack (PN Red) as the license that activates this function. The reported license number is 6ES7653-2CX01-0XE0 for a USB license key; a download option is also listed in Siemens material. Confirm the CPU firmware, System Expansion Card (SEC), PCS 7 release and intended topology before applying the license, then retry loading the hardware system data under the approved change procedure.

Why the download reports a license error

The error says no license is available for a redundant PROFINET subnetwork and that SDB 1010 cannot be loaded. Siemens documentation describes CPU 410 Expansion Pack (PN Red) as enabling redundant PROFINET configuration R1 for distributed I/O. This aligns with the reported CPU 410-5H and IM 155-6AU00-0PM0 scenario.

Check the license and CPU prerequisites

The Siemens CPU 410 material states that the PN Red expansion pack is required for redundant R1 PROFINET devices and gives license key 6ES7653-2CX01-0XE0 (USB) and 6ES7653-2CX01-0XK0 (online delivery). The V9.0 SP1 service manual describes the expansion pack upgrade scope for CPU 410-5H from firmware V8.1 or higher. Confirm the exact CPU firmware and that the license key is installed on the applicable SEC.

Correct and reload the hardware configuration

Confirm the project actually configures redundant PROFINET R1, rather than a single PROFINET subnet.
Verify the CPU 410-5H firmware and SEC state against the matching PCS 7 Readme and CPU manual.
Confirm the PN Red Expansion Pack license is available and assigned to the correct CPU/SEC; use the license key appropriate to the delivery method.
Recheck the hardware configuration and compile the system data.
With operations approval and an outage/rollback plan, load the corrected system data and verify the redundant I/O path and diagnostics.

Verification

Confirm the license is recognized by the CPU engineering workflow and that the system data load completes. Then verify both redundant PROFINET paths and ET 200SP HA communication through the project's approved redundancy checks. Do not treat a successful SDB load as proof that both paths are operational.

Limitations and Operational Precautions

The ticket does not state CPU firmware or PCS 7 version. License ordering number and firmware applicability must be checked against the installed release. Loading system data can affect a running automation system; follow PCS 7 change control and site availability requirements.

Engineer FAQ

What does CPU 410 Expansion Pack PN Red enable? It activates support for redundant PROFINET R1 configurations for distributed I/O on a CPU 410-5H.

Which license number did Siemens list for the USB key? Siemens lists 6ES7653-2CX01-0XE0; online delivery is listed as 6ES7653-2CX01-0XK0.

Does the license apply to every CPU 410-5H project? It is required for the documented redundant PROFINET R1 functionality; projects without that configuration have a different license need.

What firmware prerequisite is documented? The referenced PCS 7 V9.0 SP1 service manual describes the expansion pack upgrade for CPU 410-5H with firmware V8.1 or higher; confirm in the exact release documentation.

Where is the expansion pack license applied? The CPU 410 expansion-pack documentation describes an upgrade on the CPU's System Expansion Card. Verify the exact procedure for the installed hardware/firmware.

Why does the error mention SDB 1010? The ticket reports the system data download failing at SDB 1010 because the required redundant-subnet license was unavailable; the message is specific to the reported setup.

Does adding the license prove redundancy works? No. Verify both PROFINET paths, I/O communication and redundancy diagnostics after the approved configuration load.

Can I load the system data while production runs? That depends on the system and change impact. Plan the load with operations, backup and rollback controls.

What if the correct key is present but the error remains? Check the CPU model/firmware, SEC assignment, installed key recognition and whether the configured topology actually requires PN Red.

Does the part number alone guarantee applicability? No. Confirm the license version and CPU/PCS 7 compatibility in the current Siemens documentation.
