Resolving ET 200SP CPU 6ES7510-1SJ01-0AB0 TIA Portal V15 Errors

Resolving ET 200SP CPU 6ES7510-1SJ01-0AB0 TIA Portal V15 Errors

The SIMATIC ET 200SP CPU 6ES7510-1SJ01-0AB0 ships with firmware V2.8.3 in many production batches. When the same unit is configured in STEP 7 Professional V15 (TIA Portal V15), the hardware catalog only lists firmware versions up to V2.5. The result is a non-selectable target firmware, a blocked download, and a series of cascading diagnostic messages on the CPU's LEDs. The most common contributing causes are a TIA Portal version older than the CPU firmware and a missing or unreadable SIMATIC Memory Card. This reference walks through the diagnosis, the supported workarounds inside TIA Portal V15, and the recommended upgrade path to a current TIA Portal version that matches the on-board firmware.

1. Problem Description

Engineers commissioning an ET 200SP station frequently report the following sequence when a 6ES7510-1SJ01-0AB0 arrives from stock:

1. The CPU appears in the network view and online detection, but the device is reported with firmware V2.8.3.
2. The hardware catalog inside STEP 7 Professional V15 only offers the device up to firmware V2.5.
3. A download to the device fails, or completes with a warning that the project firmware is older than the target firmware.
4. The CPU MAINT LED is lit and the RUN LED is off, even though the SIMATIC Memory Card slot is empty.
5. The diagnostic buffer contains entries such as "Memory card missing or defective" or "Firmware version of the inserted module does not match the configured module".

These symptoms are all symptoms of the same root cause family: a version mismatch between TIA Portal and the CPU firmware, combined with the absence of a bootable SIMATIC Memory Card.

2. Affected Hardware and Firmware

The article applies to the following module, configuration, and software combination:

The 6ES7510-1SJ01-0AB0 is delivered without a SIMATIC Memory Card. The card must be ordered separately and inserted before the CPU can complete firmware consistency checks and project download.

3. Root Cause Analysis

Three independent causes can produce a failed download. Resolve them in the order listed.

3.1 Firmware newer than catalog support

STEP 7 Professional V15's hardware catalog only includes firmware versions released at the time of V15's first shipment. Newer firmware features, security fixes, and bug fixes added in V2.6, V2.7, and V2.8.x are not visible. When the online device reports a higher firmware than the catalog, TIA Portal blocks the standard download path because it cannot guarantee that the project uses only functions that exist in the target firmware.

3.2 Missing SIMATIC Memory Card

ET 200SP CPUs of the S7-1500 family are designed to boot from a SIMATIC Memory Card (SMC). The card stores the project, the firmware update package during updates, and the service data. With no card inserted, the CPU raises diagnostic interrupt "Memory card missing or defective" and refuses a download of user project data. The MAINT LED turns on and the RUN LED remains off until the card is present and the project is consistent.

3.3 Configuration control with mixed versions

When the configured firmware in the TIA Portal project is older than the firmware physically installed, TIA Portal issues a warning, not an error. The warning can be accepted, and the download proceeds with the limitations of the older configured firmware. This is the key behavior that enables the workaround described in Section 6.

4. TIA Portal / Firmware Compatibility Matrix

The compatibility between TIA Portal versions and the firmware level of the S7-1500 and ET 200SP CPU family follows the rule "Firmware X requires TIA Portal Y, where Y was the first release to support X". For the 6ES7510-1SJ01-0AB0:

5. SIMATIC Memory Card Requirements

The ET 200SP CPU will not boot a project without a valid SIMATIC Memory Card. Use the following guidance when selecting and preparing the card.

6. Workaround: Load Project Using Configured Firmware Older Than Target

This procedure lets you finish a download from TIA Portal V15 without upgrading to V16. The trade-off is that you cannot use the new features introduced in V2.8.x.

6.1 Prerequisites

• STEP 7 Professional V15 installed and licensed.
• Genuine SIMATIC Memory Card formatted by the same TIA Portal installation.
• Online connection from the engineering PC to the ET 200SP CPU (PROFINET or PROFIBUS depending on the IM).
• ET 200SP CPU in STOP (STOP/RUN switch in STOP position).

6.2 Procedure

1. Open the TIA Portal project and double-click Devices & networks.
2. Select the ET 200SP CPU and open Device view.
3. In the inspector window open Properties > General > Catalog information (or Module parameters).
4. From the Version drop-down, choose the highest firmware that STEP 7 Professional V15 displays for the 6ES7510-1SJ01-0AB0 (typically V2.5).
5. Compile the project (Project tree > Right-click CPU > Compile > Hardware (rebuild all)).
6. Right-click the CPU and choose Download to device > Hardware and software (only changes).
7. If TIA Portal reports a version mismatch warning, read it carefully. The message states that the configured firmware is older than the firmware on the target device. Click Continue to accept the warning.
8. The download proceeds and writes the project to the SIMATIC Memory Card. Wait for the Download successful dialog.
9. Switch the CPU to RUN. Verify that the RUN LED is solid green and the MAINT LED is off.

6.3 Limitations

• You will not be able to call any function, block, or system call that was added between V2.5 and V2.8.x.
• Some HMI panels, drives, or PROFINET devices configured with newer GSDML revisions may fail consistency checks if they require newer CPU firmware.
• CPU security features (e.g., improved access protection) added after V2.5 will operate but cannot be fully parameterized from V15.

7. Recommended Path: Upgrade TIA Portal to V16 or Higher

For long-term support and access to V2.8.x features, upgrade STEP 7. The migration path is straightforward because the project file is forward-compatible.

7.1 Procedure

1. Install STEP 7 Professional V16 (or later) on a separate engineering PC or in parallel on the same PC using a different installation path.
2. Open the existing V15 project. TIA Portal prompts for a project upgrade; confirm.
3. Save the upgraded project under a new name to keep the original V15 copy as a fallback.
4. Open Devices & networks and select the ET 200SP CPU.
5. Change the Version drop-down from V2.5 to V2.8.3.
6. Recompile. TIA Portal adds the missing firmware-specific objects and reports any blocks that use deprecated functions.
7. Download the project. The SIMATIC Memory Card can be reused; the firmware revision of the CPU is already V2.8.3, so the project is now consistent.

7.2 When to migrate the firmware instead

If you must stay on TIA Portal V15 because the rest of the plant is locked to V15, you can downgrade the on-board firmware of the CPU to V2.5 using the SIMATIC Automation Tool or a TIA Portal V15.1 installation. The downgrade erases V2.8.x features but resolves the version mismatch in the opposite direction (project firmware equals or exceeds target firmware).

8. Firmware Update Procedure

Use the following procedure to bring the CPU firmware to a specific version that matches your TIA Portal. This is the same procedure used to upgrade, downgrade, or repair a corrupt firmware.

8.1 Required files

• CPU firmware update file (for example, 6ES7510-1SJ01-0AB0_V28.3.upd). Obtain from Siemens Industry Online Support (SIOS) entry ID 109751706 for S7-1500 / ET 200SP CPU firmware updates.
• SIMATIC Memory Card with sufficient free space (12 MB minimum).
• STEP 7 Professional V16 or higher, or the SIMATIC Automation Tool.

8.2 Procedure with TIA Portal

1. Insert the SIMATIC Memory Card into the card reader of the engineering PC.
2. In TIA Portal, open Online > Accessible devices and select the ET 200SP CPU.
3. Open the Online & Diagnostics view of the CPU.
4. Select Firmware update from the functions list.
5. Browse to the firmware .upd file and click Run update.
6. Confirm the dialog. The CPU switches to STOP, erases the user data, writes the new firmware, and restarts automatically.
7. After restart, verify the firmware revision in Online > Accessible devices > CPU properties > Firmware.

8.3 Procedure with SIMATIC Automation Tool

1. Open SIMATIC Automation Tool and scan the network.
2. Right-click the ET 200SP CPU and choose Firmware update.
3. Select the firmware file and confirm.
4. The tool pushes the firmware via the standard PROFINET update mechanism, no card swap required.

9. Status and Error Displays

The ET 200SP CPU uses a fixed set of front-panel LEDs to report its operating state. Use the table below for fast on-site diagnosis. The complete reference is available in the ET 200SP Manual Collection, section Status and error displays, for the IM 155-6 DP HF (for example, Status and error displays of the IM 155-6 DP HF).

10. Status and Error Codes (Diagnostic Buffer)

The CPU writes structured entries to the diagnostic buffer. Some of the codes related to configuration and version mismatch are listed below. The full table is published in the ET 200SP Manual Collection — Status and error codes page. The numbering shown is the public, documented subset used during user calibration and configuration.

Codes 11, 12, and 13 are part of the documented Status and error codes table for user calibration. Codes 07, 08, 16, 17, and 128 are part of the standard S7-1500/ET 200SP diagnostic code set and are reproduced here as they are commonly encountered during the firmware version resolution process.

11. Diagnostic Procedure for the Mismatch Condition

Use this checklist when the download fails or the CPU stays in STOP after the SIMATIC Memory Card is inserted.

1. Open TIA Portal, connect to the CPU via Online > Accessible devices, and read the diagnostic buffer.
2. Confirm the on-board firmware version (for example, V2.8.3). If the catalog version in your TIA Portal is older, the buffer will contain an entry starting with "Firmware version of the inserted module does not match...".
3. Insert a genuine SIMATIC Memory Card if not already present. Power-cycle the CPU.
4. If the MAINT LED remains lit, perform an Memory reset via the front-panel STOP/RUN switch sequence: STOP → MRES (hold 3 s) → STOP → MRES (briefly). The CPU performs a factory reset and is ready to receive a new project.
5. Recompile the project and download again, using the workaround of Section 6 if the catalog does not list the on-board firmware.
6. If the issue persists, perform a firmware downgrade to a version supported by the current TIA Portal (Section 8).

12. Verification Steps

After applying either the workaround or the upgrade path, confirm the following before handing the station over to production.

1. The RUN LED is solid green; the MAINT and ERROR LEDs are off.
2. The TIA Portal project shows the CPU in Online > Online & Diagnostics > Diagnostics status with status "OK".
3. The diagnostic buffer contains no entries with severity Error for the last 10 minutes of operation.
4. The configuration in the CPU (uploaded via Device > Upload to PG/PC) matches the offline project, including firmware version.
5. All PROFINET devices come up without diagnostics; PROFINET diagnosis shows all devices in "Data exchange" state.
6. A simple read/write test of a process tag confirms the program executes end-to-end (for example, set a marker and read it back from an HMI or via a watch table).

13. Preventive Recommendations

• Keep a central log of CPU MLFBs and on-board firmware versions per cabinet to avoid surprises during commissioning.
• Lock the engineering tool version in the project properties ("Use TIA Portal version that matches the highest firmware used in the project") to prevent version drift.
• Always have at least one spare, pre-formatted SIMATIC Memory Card per ET 200SP CPU on site.
• Pin the TIA Portal installation to a single version per project. Mixed projects (V15 for some CPUs, V16 for others) require careful migration management.
• Subscribe to Siemens Product Safety and Security advisories to stay informed about firmware updates that may force a TIA Portal upgrade.
