SIMOTION SCOUT TIA V4.4 HF6 ET200MP Timer DIDQ Integration

Overview

SIMOTION SCOUT TIA V4.4 is the engineering environment for SIMOTION D4xx-2 controllers, including the D425-2 DP/PN, when configured inside TIA Portal. The V4.4 release line required a sequence of hotfixes to enable the full ET200MP I/O feature set, in particular the Timer DIDQ technology module functionality on the ET200MP station. Without the matching hotfix, the technology module is recognized as a non-functional slot or the configuration download terminates during HW Config consistency checks.

This reference documents the supported hotfix levels for the V4.4 branch, the relationship to TIA Portal V13.0 SP1, the configuration steps required to operate a Timer DIDQ on a SIMOTION D425-2, and the diagnostic path when the module does not appear in the device catalog. The starting point for the official Siemens knowledge base entry is Product Support Entry ID 109476916.

SIMOTION SCOUT TIA V4.4 Hotfix Roadmap

The V4.4 line of SCOUT TIA was delivered with multiple hotfixes. Each hotfix is delivered as a Siemens service pack and is required only for the use cases defined in its release notes. The following table summarizes the publicly documented hotfix levels relevant to ET200MP integration:

ET200MP and Timer DIDQ Functional Scope

The ET200MP is the modular remote I/O system based on the SIMATIC S7-1500 backplane. The I/O interface module 1500 (IM 155-5 PN) is the PROFINET head-end module that connects the ET200MP station to a PROFINET IO Controller such as the D425-2 PN. The Timer DIDQ is a technology module that provides high-precision digital inputs and outputs with time stamping and oversampling capability, designed for measurement, dosing, and cam-disc replacement applications.

Key functional characteristics of the Timer DIDQ on a SIMOTION controller:

• Time-stamped digital inputs with microsecond resolution for synchronization with the SIMOTION clock.
• High-speed digital outputs with selectable output modes (direct, override, substituted value).
• Technology objects for TO_Dosing, TO_CamTrack, and TO_OutputCam on the SIMOTION side that reference the module's I/O channels.
• Configuration of the technology parameters in TIA Portal; binding to SIMOTION technology objects in SCOUT TIA.

On a SIMOTION D425-2, the Timer DIDQ can only be configured in the ET200MP station if the project is opened in TIA Portal, not in the classic SCOUT standalone engineering tool. The binding to SIMOTION technology objects (interconnection in the SIMOTION address list) is then performed in SCOUT TIA.

Compatibility Matrix

The following matrix defines the supported combinations of SCOUT TIA version, TIA Portal version, and SIMOTION controller firmware for ET200MP Timer DIDQ operation.

Prerequisites for HF6 Deployment

Before applying HF6, verify the following conditions in the engineering environment and the target controller:

1. Engineering PC operating system: Windows 7 SP1 (64-bit) or Windows Server 2008 R2 SP1. TIA Portal V13.0 SP1 is not validated on Windows 10 for the V13 generation.
2. Installed TIA Portal: TIA Portal V13.0 SP1 with the SIMOTION option package activated. The SIMOTION option package adds the SIMOTION D4xx-2 device catalog entries and the technology objects used in the Timer DIDQ path.
3. Installed SCOUT TIA: SCOUT TIA V4.4 base installation with the matching Update DVD or Service Pack. Confirm the base build number before applying HF6.
4. HF6 package: Obtain the HF6 service pack from the Siemens Industry Online Support portal under entry ID 109476916, then run the setup on top of the existing V4.4 base.
5. Controller firmware: The D425-2 must run the firmware that matches the V4.4 SCOUT TIA version line. Use SIMOTION SCOUT or the web server of the D425-2 to read the firmware version (menu Diagnostics > Version).
6. PROFINET topology: The ET200MP station with the IM 155-5 PN must be reachable on PROFINET and the device name must be assigned. The D425-2 must be configured as PROFINET IO Controller and the IM 155-5 PN as PROFINET IO Device.

Configuration Procedure

The configuration of the Timer DIDQ on a D425-2 is performed in TIA Portal and completed in SCOUT TIA. The procedure is split into two phases: the device/network phase in TIA Portal and the technology binding phase in SCOUT TIA.

Phase 1 — TIA Portal Device and Network Configuration

1. Open the TIA Portal project that contains the D425-2. If the project is currently a classic SCOUT standalone project, migrate it to a TIA Portal integrated project with Project > Migrate project before continuing.
2. In Devices & Networks, add the D425-2 to the project if not already present. The D425-2 device catalog entry is supplied by the SIMOTION option package.
3. Insert a new ET200MP station. In the device catalog, expand ET200MP > Interface modules > PROFINET > IM 155-5 PN and drag the head-end module into the project.
4. Connect the IM 155-5 PN to the PROFINET subnet of the D425-2. Assign the IM a unique PROFINET device name and IP address consistent with the plant network plan.
5. Open the ET200MP station and insert the Timer DIDQ technology module into an available slot of the ET200MP backplane. The module is found under ET200MP > I/O modules > Technology modules > Timer DIDQ. Verify that the slot is allowed for the module (technology modules have restricted slot rules).
6. Configure the channels of the Timer DIDQ (input filter, output mode, time-stamp resolution) in the module properties. Save the project and download the hardware configuration to the D425-2 and to the IM 155-5 PN.
7. Run the TIA Portal consistency check. Any inconsistency (wrong slot, missing PROFINET name, IP conflict) prevents the project from compiling.

Phase 2 — SCOUT TIA Technology Binding

1. Switch to SCOUT TIA and open the same project. The Timer DIDQ slot appears in the SIMOTION address list.
2. Insert a technology object matching the application: TO_Dosing, TO_CamTrack, or TO_OutputCam. The technology object type is selected based on the function of the Timer DIDQ channel.
3. In the configuration of the technology object, set the I/O assignment to the Timer DIDQ channel address (for example, I 100.0 / Q 100.0 on the ET200MP slot). SCOUT TIA resolves the address through the TIA Portal hardware configuration; manual address editing is not permitted.
4. Compile the SIMOTION project and download the configuration to the D425-2.
5. Run the SCOUT TIA consistency check. The check verifies that the technology object is bound to an existing Timer DIDQ slot and that the configured timing parameters are within the module's range.

Migration from Integrated I/O to ET200MP Timer DIDQ

If a previous application used the D425-2 on-board I/O (integrated DI/DO on the controller front panel) to perform a function that the Timer DIDQ is intended to replace (for example, high-speed dosing or time-stamped input capture), the migration follows this pattern:

1. Document the existing SIMOTION program structure: technology object configuration, address references, and program code that uses the on-board I/O symbols.
2. Add the ET200MP station and the Timer DIDQ to the TIA Portal hardware configuration as described in the configuration procedure.
3. In the SIMOTION program, remap the technology object I/O assignment from the on-board I/O symbol to the Timer DIDQ slot address. The on-board I/O symbols are typically IO.di[0..15] and IO.do[0..15] on the SIMOTION D4xx-2.
4. Replace any direct access to the on-board I/O with the technology object access. The technology object abstracts the I/O and provides the high-precision timing functions that the on-board I/O cannot deliver.
5. Run the SCOUT TIA download to the D425-2 with the new configuration. The on-board I/O is left unused; it is not removed from the hardware configuration to keep the migration reversible.

Diagnostic and Verification

When the Timer DIDQ is not operational on a D425-2, the following diagnostic path is applied in sequence. Each step references the entry ID 109476916.

If step 3 fails with the "HF6 required" message, apply the HF6 service pack from entry ID 109476916 and repeat the configuration. If step 7 fails with a module failure, check the IM 155-5 PN diagnostics buffer for the slot number and the error code, then reference the SIMATIC ET200MP system manual for the diagnostic code meaning.

PROFINET Topology and Timing Constraints

The Timer DIDQ is timing-critical. The following parameters must be set in the PROFINET topology to achieve the module's specified accuracy:

• Send clock: The PROFINET send clock for the ET200MP subnet must be 1 ms or lower. The default in TIA Portal is 1 ms; do not increase it above the Timer DIDQ specification.
• IO update time: The IO update time on the IM 155-5 PN must be a multiple of the send clock and must be configured to match the technology object cycle clock in SCOUT TIA.
• Topology detection: Enable PROFINET topology detection on the D425-2 port to which the IM 155-5 PN is connected. Topology detection reports port and cable errors that would otherwise silently degrade the time stamping.
• Real-time setting: The PROFINET subnet must be configured for real-time (RT), not IRT. Timer DIDQ on the D425-2 is not validated for IRT-only operation in the V4.4 line.

Firmware Update Procedure for the D425-2

When the controller firmware must be updated to match the SCOUT TIA V4.4 hotfix line, use the following path:

1. Open SCOUT TIA and connect to the D425-2 in online mode using the configured PROFINET interface.
2. Open the Target system > Firmware update dialog and select the firmware file matching the V4.4 SCOUT TIA line.
3. Transfer the firmware to the controller. The D425-2 automatically restarts with the new firmware image.
4. After restart, reconnect in SCOUT TIA and verify the firmware version in Target system > Diagnostics > Version.
5. Download the project to the controller to refresh the configuration that matches the new firmware version.

Known Limitations and Field-Proven Caveats

• The Timer DIDQ on the D425-2 is restricted to the ET200MP station topology. The technology module is not supported in the SIMOTION D4xx-2 on-board I/O or in a PROFIBUS DP segment.
• SCOUT standalone (the classic engineering tool, not the TIA Portal integration) does not show the Timer DIDQ in the device catalog, even with HF6 installed. The technology module can only be configured in SCOUT TIA (TIA Portal integrated mode).
• Mixed configurations that combine the ET200MP Timer DIDQ and PROFIsafe modules on the same ET200MP station require TIA Portal V13.0 SP1 Update 5 or higher. Verify with the release notes of the specific update level.
• The Timer DIDQ is not part of the standard SIMOTION technology object bundle. The technology object license is required on the engineering PC and the runtime license is required on the D425-2 for the technology to be active at runtime.
