Resolving SCOUT TIA V14 Compatibility for SIMOTION Projects

Overview

SIMOTION engineers who adopt TIA Portal V14 must reconcile two parallel toolchains: the TIA Portal engineering framework and the SCOUT TIA option package that programs the SIMOTION motion controllers (D4xx, P320, etc.). SCOUT TIA V4.4 (HF6 through HF11) was engineered against TIA Portal V13 SP1 and is not compatible with TIA Portal V14. A separate SCOUT TIA release, V4.5.x, was published in late 2016 to add TIA V14 support, new PROFIdrive alarm handling, and updated hardware catalog data.

This reference documents the compatibility matrix between SCOUT TIA and TIA Portal versions, the project upgrade path from V13 SP1 to V14, the hardware/VM sizing rules for a usable engineering workstation, and the procedure for configuring devices that SCOUT TIA cannot program — notably the SIMOTION P320-4 — through STARTDRIVE in TIA Portal V14.

SCOUT TIA vs. TIA Portal Compatibility Matrix

The compatibility envelope is strict: SCOUT TIA acts as an optional package installed on top of a base TIA Portal version. The table below lists each SCOUT TIA version, the matching TIA Portal version, the SIMOTION firmware it can program, and the release date.

Why SCOUT TIA V4.4 Fails Under TIA Portal V14

SCOUT TIA V4.4 ships against the TIA Portal V13 SP1 automation interface. When the SCOUT TIA option package loads, it interrogates the installed TIA Portal build number and refuses to attach to any V14 build. Symptoms observed on engineering workstations:

1. SCOUT TIA option does not appear in the TIA Portal tree under Options > SIMOTION.
2. TIA Portal starts in V14 mode but throws 0x011A: Option package incompatible with current TIA Portal version when launching SCOUT.
3. Device library entries for SIMOTION are greyed out in the hardware catalog.
4. Existing V13 SP1 SIMOTION projects cannot be opened directly from V14 without project migration.

There is no compatibility mode and no back-port. Engineers must upgrade SCOUT TIA to V4.5.x alongside the TIA Portal V14 upgrade.

SCOUT TIA V4.5 New Features

The V4.5 release introduced several capabilities that affect commissioning and diagnostics workflows:

• PROFIdrive alarm routing for SINAMICS S120 with CU320-2 control units: SINAMICS drive alarms are now forwarded into the SIMOTION diagnostic buffer and exposed to HMI panels without a separate WinCC alarm mapping. This addresses the recurring field issue where a customer reports a blocked machine with only a red LED on the SIMOTION — operators now see the underlying SINAMICS fault number on the HMI.
• Catalog update for D425-2 DP/PN with firmware V4.5.
• Updated device proxy for CP1542SP-1 (the ET 200SP CPU used as a SIMOTION-side PROFIBUS master) — required for projects that bridge TIA V14 hardware into an existing SIMOTION line.
• Side-by-side install support: SCOUT TIA V4.4 and V4.5 can coexist if TIA V13 SP1 and V14 are installed in separate TIA Portal environments.

Side-by-Side Installation of TIA V13 SP1 and V14

Many SIMOTION sites cannot upgrade legacy projects in a single cut-over. Siemens supports installing TIA Portal V13 SP1 and V14 on the same engineering workstation, with SCOUT TIA V4.4 attached to V13 SP1 and SCOUT TIA V4.5 attached to V14. The two toolchains are isolated by separate TIA Portal registries and project folders.

Procedure:

1. Verify TIA Portal V13 SP1 with all SIMOTION HSPs is installed and projects open cleanly before adding V14.
2. Run the TIA Portal V14 installer; do not remove V13 SP1. Confirm both versions appear in Control Panel > Programs and Features.
3. Install SCOUT TIA V4.5 as an option package; it auto-detects the V14 base and binds to it.
4. Open V13 SP1 projects by launching the V13 SP1 TIA Portal executable directly; do not double-click .ap13 files from Windows Explorer.

Project Upgrade Path: V13 SP1 → V14

SCOUT TIA enforces a strict upgrade gate. The migration ladder is:

The V14 launcher does not automatically re-route a V13 project to the V13 SP1 environment. If a V13 (non-SP) project is opened with the V14 launcher, the upgrade is refused with error Project was created with TIA Portal V13. Update to V13 SP1 first.

Workstation Hardware and Virtualization Sizing

SCOUT TIA plus TIA Portal plus a WinCC Flexible/Comfort runtime on a single workstation taxes even modern hardware. The minimum and recommended configurations observed in production engineering environments are:

Engineers running TIA + SCOUT + WinCC on a low-RAM laptop report multi-second UI freezes when switching between editors. The recommended mitigation is a dedicated VM containing only the Siemens toolchain, hosted on a workstation with 16 GB RAM and an SSD-backed VM disk.

Virtual Machine Deployment Best Practices

Because the Siemens toolchain interacts deeply with COM, DCOM, and the Windows security subsystem, antivirus software frequently corrupts TIA project files mid-save. A controlled VM provides isolation and reproducibility.

1. Build a Windows 7 SP1 or Windows 10 LTSC VM with 4 vCPU, 12 GB RAM, and 120 GB dynamic VDI on SSD storage.
2. Install SIMATIC Automation License Manager before TIA Portal.
3. Install TIA Portal V14 + SCOUT TIA V4.5 in a single uninterrupted session.
4. Exclude the VM directory from host-side antivirus real-time scanning.
5. Snapshot the VM after a clean compile of a reference project; restore the snapshot before re-installing updates.
6. Allocate USB license dongle passthrough exclusively to the VM to avoid COM port conflicts.

Engineers running i5/6 GB laptops should not attempt SCOUT TIA V4.5 inside a VM; the working memory pressure triggers TIA Portal crashes with S7DOS error 0x80004005.

Configuring the SIMOTION P320-4 in TIA Portal V14

The SIMOTION P320-4 (PC-based motion controller with the P320-4 panel) is not supported in SCOUT TIA under any version, including V13, V13 SP1, and V14. The P320-4 must be configured using STARTDRIVE integrated in TIA Portal V14.

Reference: Siemens KB 68034568 — STARTDRIVE for TIA Portal V14

Procedure to commission P320-4 with STARTDRIVE:

1. Install the STARTDRIVE V14 HSP (Hardware Support Package) via the TIA Portal Options > Support Packages menu.
2. Open or create the TIA Portal V14 project.
3. Add a PC station and select the SIMOTION P320-4 from the catalog tree: PC Systems > SIMOTION > P320-4.
4. Insert the SINAMICS drive (S120, V90, or G120) as a subordinate PROFIdrive device under the P320-4 PROFINET interface.
5. Assign the drive telegram (typically Telegram 105 for S120 with extended diagnostics) in the drive's Properties > PROFINET interface > Telegram configuration.
6. Configure the axis in the SCOUT-style technology object tables using the STARTDRIVE graphical editor; the resulting data blocks are stored under the P320-4's program folder.
7. Compile and download to the P320-4 runtime; verify with the Online > Diagnostics view that the axis is in RUN state and the PROFIdrive status word ZSW1 bit 0 (Ready to switch on) is set.

When to Use SCOUT TIA vs. STARTDRIVE

SCOUT TIA Does Not Program S7-Direct Servo Drives

A common misconception is that SCOUT TIA can configure SINAMICS servo drives attached directly to an S7-300/400/1200/1500 PLC. This is not supported. SCOUT TIA's role is to program SIMOTION controllers and the drives that are assigned to a SIMOTION as the PROFIdrive master. Drives assigned to a S7 CPU must use:

• STARTDRIVE (TIA Portal V14 and later) — preferred for new S7-1200/1500 projects.
• STARTER — legacy tool for S7-300/400 projects, supports S120, G120, V20.
• SINAMICS V-Assistant — for V20 commissioning via USS/Modbus.

Commissioning Sequence for a TIA V14 SIMOTION Project

1. Install TIA Portal V14 + SCOUT TIA V4.5 on the engineering workstation (or VM).
2. Create a new project; insert the SIMOTION controller (e.g., D425-2 DP/PN) from the catalog.
3. Insert the SINAMICS drives under the SIMOTION PROFINET subnet.
4. Configure the axes, cams, and gears as technology objects in SCOUT TIA.
5. Write the application in Structured Text (ST), Motion Control Chart (MCC), or Ladder Diagram (LAD).
6. Compile the project; resolve any cross-compile errors reported in the Info > Compile tab.
7. Connect to the SIMOTION controller via the configured PROFINET interface.
8. Download the project to the target with the Download to target system button; select Download entire project for first commissioning.
9. Run the controller in RUN mode and verify axis motion using the Trace recorder.
10. Save the project archive to the SSD-backed data folder; export the SIMOTION trace buffer for sign-off documentation.

Troubleshooting Matrix

Field-Proven Caveats

• SCOUT TIA option package uninstall is not clean. Residual registry entries force a manual cleanup with the Siemens Automation Cleanup tool before re-installing a different SCOUT TIA version.
• Trace recordings from a V4.4 project are forward-compatible with V4.5; backward compatibility is not guaranteed.
• Siemens releases SCOUT TIA service packs asynchronously from TIA Portal service packs. Always check the SCOUT TIA compatibility note in KB 109476392 before applying a TIA Portal update.
• Windows 11 24H2 introduced a known issue with the SIMATIC License Manager USB driver. Roll back to Windows 10 LTSC if dongle-based licensing fails intermittently.
• The Microsoft Scout product is unrelated to SIMOTION SCOUT. Any internal documentation referencing Scout in the context of Office 365, document automation, or AI agents refers to the Microsoft tool, not the Siemens motion engineering tool.
