Fixing ET 200S CPU Missing in TIA Portal V14 SP1 Device Catalog

1. Problem Statement

When adding a new device in TIA Portal V14 SP1, the SIMATIC ET 200S distributed I/O controller 6ES7151-8FB01-0AB0 (IM151-8 PN/DP CPU) does not appear in the device catalog. The hardware catalog either displays no matching entry, shows the module greyed out, or only lists it under non-ET 200S branches (e.g. Other field devices). Installing the relevant Hardware Support Package (HSP) does not fix the issue.

This symptom is commonly encountered on engineering workstations licensed for STEP 7 Safety Basic / Advanced V14 SP1 without a STEP 7 Professional license. The Safety option package is a runtime/integrated add-on and does not upgrade the base STEP 7 edition.

The TIA Portal launch dialog and Help > About dialog reveal which base package is installed:

• STEP 7 Basic V14 SP1 – S7-1200 only
• STEP 7 Professional V14 SP1 – S7-1200, S7-300, S7-400, S7-1500, ET 200 CPUs (incl. ET 200S, ET 200pro, ET 200SP)

2. Affected Hardware and Software

2.1 Affected module

2.2 Affected software editions

3. Root Cause Analysis

The ET 200S IM151-8 PN/DP CPU is an S7-300-class controller. In TIA Portal, S7-300 and ET 200S CPU modules are gated behind the STEP 7 Professional license. The catalog filtering is enforced by the TIA Portal portaland is not resolved by installing a Hardware Support Package (HSP).

The flow that produces the symptom is shown below.

The HSP mechanism is intended to add new or post-release modules to the catalog for an already supported family. It cannot promote a CPU family from one base edition to another. Confirming the edition via Help > About > Installed products is the fastest way to disambiguate the cause.

4. Solution: Install STEP 7 Professional TIA Portal

4.1 Prerequisites

• Windows 7 SP1 / Windows 10 (64-bit) compatible with TIA Portal V14 SP1
• STEP 7 Professional V14 SP1 installation media or upgrade license (e.g. 6ES7822-1AA04-0YA5 for STEP 7 Professional V14 SP1 floating license)
• If F-programming is required: STEP 7 Safety Advanced V14 SP1 (6ES7833-1FA14-0YA5) installed on top of Professional
• Administrator rights on the engineering station
• Existing TIA Portal projects: take a full project backup (TIA Portal Project > Archive) before performing an edition upgrade

4.2 Step-by-step upgrade procedure

1. Close all running TIA Portal instances.
2. Insert the STEP 7 Professional V14 SP1 DVD or mount the ISO; alternatively run the downloaded Setup.exe.
3. When the product selection dialog appears, confirm STEP 7 Professional V14 SP1 is checked.
4. If you already have Safety Advanced V14 SP1 installed, choose Modify/Upgrade and accept the existing Safety license. The Safety package will be re-paired with the new base edition.
5. Transfer the STEP 7 Professional license (floating or single) using Siemens Automation License Manager and confirm the license is assigned to the local PC.
6. Restart the engineering station when prompted.
7. Launch TIA Portal V14 SP1. Open Help > About > Installed products and verify both STEP 7 Professional V14 SP1 and (if applicable) S7-PLCSIM / Safety are listed.

4.3 Post-upgrade verification

1. Open a new project. The Add new device dialog should now expose the path SIMATIC ET 200S > Interface modules > IM151 CPU > IM151-8 PN/DP CPU.
2. Insert 6ES7151-8FB01-0AB0 into the project. The device view opens without warnings.
3. Open the Online > Accessible nodes dialog and confirm the module responds on PROFINET/PROFIBUS.

5. Hardware Support Package (HSP) Installation

Once STEP 7 Professional is installed, install the matching HSP to ensure the device appears in the catalog with the correct firmware revision and module revisions.

5.1 Locating the correct HSP

For TIA Portal V14 SP1, search the Siemens Industry Online Support portal for the ET 200S HSP that corresponds to V14 SP1 (e.g. HSP V14 SP1 for ET 200S). Always pick the HSP whose TIA Portal version line matches the installed TIA Portal version exactly; mismatched HSPs are silently ignored or warn at install time.

5.2 Installation procedure

1. Close TIA Portal.
2. Double-click the downloaded .hsp file. The HSP installer starts automatically.
3. Confirm the target directory (default: C:\Program Files\Siemens\Automation\Portal V14 SP1\Hsp).
4. Restart TIA Portal V14 SP1.
5. Open the project, right-click the device and select Hardware catalog > Update (or restart with the Hardware catalog filter cleared).

5.3 Verifying HSP content

After installation, the new device version appears in the catalog as e.g. 6ES7151-8FB01-0AB0 / V3.x. Right-click the catalog entry and select Properties to confirm version and supported firmware.

6. Configuring the ET 200S IM151-8 PN/DP CPU

After the module is inserted into the project, the standard engineering workflow follows the procedure documented in the TIA Portal V14 SP1 online help under Editing devices and networks > Creating configurations > Configuring PROFIBUS DP (S7-300/S7-400/S7-1500) > Example: Configuring ET 200S as DP slave (S7-300/S7-400/S7-1500) > Configuring an ET 200S.

6.1 Project structure

1. Insert the IM151-8 PN/DP CPU in the device view.
2. Add PROFINET IO devices on the integrated switch (port 1 / port 2 / port 3).
3. Add PROFIBUS DP slaves on the integrated DP master port if used as a master.
4. Insert power modules and electronics modules (PM-E, digital, analog) in the slot rules of the ET 200S backplane.

6.2 Example: Inserting a 2AI RTD HF analog module

The 2AI RTD HF (e.g. 6ES7134-4JB51-0AB0) supports the thermal resistor measuring type. The configuration steps in the device view are:

1. Open the ET 200S device view.
2. Drag the 2AI RTD HF from Catalog > AI > RTD onto a free slot.
3. Open Properties > Inputs > Channel 0 / Channel 1.
4. Set Measurement type to Thermal resistor and pick the sensor curve (Pt100, Pt1000, Ni100, etc.).
5. Set Temperature unit (°C default) and Smoothing.
6. Compile the configuration (HW).

The module returns a temperature in 0.1 °C resolution (integer in °C × 10). Use the system function block SCALE or simple integer division to convert.

7. PROFINET and PROFIBUS Network Configuration

7.1 PROFINET IO controller

The IM151-8 PN/DP CPU has an integrated 3-port PROFINET switch (ports 1/2/3) and can act as a PROFINET IO controller. In the device view:

1. Open Properties > PROFINET interface > Ethernet addresses.
2. Set IP address (default 0.0.0.0 until assigned), Subnet mask, and Router address.
3. Assign a PROFINET device name (e.g. et200s-cpu-1). This name must be assigned to the physical device via Online > Accessible devices > Assign PROFINET device name.
4. Configure update time (RT class 1 default: 1 ms; can be raised to 128 ms for non-time-critical I/O).

7.2 PROFIBUS DP master/slave

The integrated PROFIBUS interface supports both DP master (class 1) and DP slave (class 1/2). The DP master mode is configured under Properties > PROFIBUS interface > DP master; the slave mode is configured under DP slave. Standard DP baud rates up to 12 Mbps are supported.

7.3 Firmware update

Use Online > Accessible devices > Firmware update to load a newer firmware. For the IM151-8 PN/DP CPU the firmware is delivered as an .upd file. The module must be in STOP for the update to complete.

8. Verification Procedures

8.1 Compile and download

1. Compile the project (HW + SW). TIA Portal reports any catalog / version mismatches in the Info pane.
2. Connect the engineering station to the ET 200S CPU via PROFINET (default IP 192.168.0.1) or PROFIBUS.
3. Use Online > Accessible nodes to confirm the CPU responds.
4. Download the project (CPU > Download to device).
5. Start the CPU in RUN. Verify the green RUN LED is on and that the I/O is updating by monitoring a tag in the watch table.

8.2 Diagnostics

Open Online & diagnostics > Diagnostics buffer to inspect events. Typical early events for a correctly commissioned IM151-8 PN/DP CPU include:

• Startup completed (Event ID 0x1310)
• PROFINET IO controller: ready for communication
• PROFIBUS DP master: bus running

If the IM151-8 PN/DP CPU logs Parameter error in central configuration (Event ID 0x13B1), check that all inserted electronics modules are physically present and that the module versions in the catalog match the installed hardware.
