Product Overview

The Schneider Electric HMIPEXCZLSRAZZ is a Professional Buildtime License for EcoStruxure Operator Terminal Expert, an engineering software platform used to develop and configure industrial HMI applications. Unlike a permanent software license, this model provides a fixed three-month authorization for one engineering workstation.

The license is intended for engineers, OEM machine builders, and system integrators who need temporary access to the Professional development environment. It is particularly useful during machine development, HMI migration, commissioning, application modification, and short-term automation projects where a permanent engineering license may not be necessary.

EcoStruxure Operator Terminal Expert provides the tools needed to create graphical operator screens, configure communication with automation equipment, organize machine data, and develop application functions. Engineers can build screen navigation structures, configure alarms, display process variables, and customize the operator interface according to the machine’s operating requirements.

The Professional edition also supports advanced engineering functions such as flexible scripting, Web Server API, and OPC UA capabilities on compatible target platforms. These functions are useful when an HMI application needs to exchange information with other automation devices or integrate with a broader industrial control architecture.

HMIPEXCZLSRAZZ is a digital, node-locked, single-station license. Its three-month validity makes it suitable for temporary engineering assignments, software evaluation projects, and time-limited HMI development work.

The software can be used for compatible Harmony HMI platforms, including GTU, GTO, STO7, ST6, STM6, and Harmony industrial PCs, subject to software-version and target-device compatibility.

• Professional Buildtime Environment

  The license provides access to the Professional engineering environment of EcoStruxure Operator Terminal Expert. Engineers can create and modify HMI applications, configure graphical interfaces, and prepare projects for compatible Harmony terminals and industrial PCs.

• Three-Month Fixed-Term Authorization

  Unlike HMIPELCZLSPAZZ, which is a perpetual Professional Buildtime license, HMIPEXCZLSRAZZ has a defined three-month usage period. This makes it suitable for temporary engineering assignments and projects with a limited development schedule.

• Single-Station Licensing

  The license is allocated to one engineering workstation. Its node-locked configuration is relevant when managing software access for individual engineers or temporary project computers.

• Digital License Delivery

  The license is supplied in digital format. This avoids the need for physical software media and supports electronic license activation.

• Graphical HMI Application Development

  The engineering environment allows developers to organize screens, configure graphical objects, create navigation structures, and display machine operating information. Common elements include numerical indicators, status displays, alarm lists, and operator controls.

• Flexible Scripting

  Professional Buildtime supports scripting for application functions that require customized behavior. This is useful when standard screen configuration is insufficient for a particular machine workflow.

• Industrial Communication Configuration

  Engineers can configure available communication drivers to exchange data with compatible PLCs and automation equipment. Communication settings and data mappings can be organized within the HMI project.

• Alarm and Event Management

  Alarm functions allow developers to configure fault messages and operating notifications. These functions help operators identify abnormal machine conditions through the HMI.

• Sampling and Trending

  Sampling and trending functions support the presentation of changing process variables over time. Typical applications include monitoring pressure, temperature, production values, and other machine operating data.

• Professional Integration Functions

  The Professional edition supports advanced functions such as Web Server API and OPC UA on compatible hardware and software configurations. These capabilities are useful when integrating HMI applications with other industrial systems.

• Multiple Harmony Platform Compatibility

  The software supports several Harmony HMI and industrial PC platforms, subject to the installed software version and target-device requirements.

Working Principle

HMIPEXCZLSRAZZ functions at the engineering level rather than the machine-control level. Its purpose is to authorize the development and modification of HMI applications within EcoStruxure Operator Terminal Expert for a limited period.

After installation and license activation, the engineer opens the development environment and creates a project for the intended Harmony HMI or compatible industrial PC. The target device is selected first because display capabilities, available interfaces, and supported functions can differ between hardware platforms.

The engineer then builds the operator interface by arranging graphical objects and defining screen navigation. Process values, equipment status indicators, alarm messages, and operator input fields are added according to the machine’s requirements.

Communication drivers are configured to connect the HMI application with the PLC. For example, a pressure display can be linked to a controller variable, while an operator input field can be configured to write an authorized setpoint to the PLC.

After the application has been configured, the project is tested and transferred to the target device. During actual operation, the HMI runtime application exchanges data with the controller and displays machine information to the operator.

The three-month license period applies to the engineering authorization. It should not be confused with the runtime operation of an already deployed HMI application. Buildtime and runtime are separate licensing functions, and their requirements depend on the target hardware.

Typical Engineering Workflow:

Engineering Workstation → HMIPEXCZLSRAZZ License Activation → EcoStruxure Operator Terminal Expert → Screen Development → Communication Configuration → Application Transfer

Typical Runtime Communication Path:

PLC / Controller → Industrial Communication Network → HMI Runtime Application → Operator Display → Operator Input → PLC

Typical Project Development Stages:

1. Install EcoStruxure Operator Terminal Expert on the engineering workstation.
2. Activate the three-month Professional Buildtime license.
3. Select the compatible target Harmony HMI or industrial PC.
4. Create screen layouts and configure navigation.
5. Define communication drivers and PLC variables.
6. Configure alarms, scripts, and process displays.
7. Test and transfer the completed application to the target device.

Role in EcoStruxure HMI Control Architecture

Within the EcoStruxure HMI architecture, HMIPEXCZLSRAZZ serves as a temporary engineering authorization for developing and modifying operator interface applications.

It belongs to the software development layer rather than the physical control layer. The engineering workstation hosts EcoStruxure Operator Terminal Expert, while the connected PLC and HMI hardware perform their respective runtime functions.

For example, an OEM machine builder may use this license to develop an HMI project for a packaging machine. The engineering workstation is used to configure the display screens, PLC communication, alarms, and operator controls. Once the project has been validated, it is transferred to the compatible Harmony terminal.

The PLC continues to handle machine sequencing, field signal processing, and equipment control. The HMI runtime application presents information and receives operator commands, while the Buildtime software provides the environment used to create that application.

The distinction between fixed-term Buildtime licensing and permanent licensing is particularly important when planning engineering resources. HMIPEXCZLSRAZZ provides one engineering station with a three-month authorization, whereas the HMIPELCZLSPAZZ provides a permanent single-station Professional Buildtime license.

Technical FAQs

How long can HMIPEXCZLSRAZZ be used after activation?

HMIPEXCZLSRAZZ is a three-month fixed-term Professional Buildtime license. Its authorization period is different from the perpetual licensing arrangement of HMIPELCZLSPAZZ. The activation date should be recorded when planning the engineering schedule.

Can HMIPEXCZLSRAZZ be installed on multiple engineering computers?

This model is a single-station, node-locked license intended for one engineering workstation. It should not be treated as a group or team license that provides multiple simultaneous development stations.

Does the three-month license also provide runtime authorization for Harmony industrial PCs?

No. Buildtime and runtime are separate licensing functions. HMIPEXCZLSRAZZ authorizes HMI application development. Running an EcoStruxure Operator Terminal Expert application on a compatible Windows-based industrial PC may require a separate runtime license, depending on the target platform.

What happens to an HMI project after the fixed-term Buildtime authorization expires?

The three-month period applies to the engineering license, not automatically to the runtime operation of an application already deployed on compatible HMI hardware. However, further project development or modification requires an appropriate valid Buildtime authorization. Existing project files should be backed up before the license period ends.
