Product Overview
The Schneider Electric HMISCU6B5 is a Harmony SCU small touch HMI controller that combines a 3.5-inch color touchscreen with programmable machine-control functions. It is suited to compact automation equipment where operators need a local interface while the same device handles digital signals, analog measurements and control outputs.
Unlike the HMISCU6A5 digital-I/O variant, the HMISCU6B5 includes analog input and output capabilities. Its configuration supports applications that need to monitor temperature or other analog signals alongside discrete sensors and actuators. Typical examples include compact packaging equipment, material-handling systems and small process machines with local operator control.
The controller operates from a 24 V DC supply and provides Ethernet, USB, serial and CANopen communication interfaces. The touchscreen can display operating values, machine states, alarms and adjustment screens, while the embedded controller executes the application logic. HMI screens, I/O assignments and communication settings are configured through the compatible Schneider Electric engineering environment.

Working Principle
The HMISCU6B5 combines a touchscreen operator interface with embedded control logic. Digital inputs receive signals from switches and discrete sensors, while analog inputs acquire supported process signals. The controller executes the configured application and updates its outputs according to the program.
For example, a compact packaging machine may use digital inputs to detect product position, analog inputs to monitor a process variable, and digital or analog outputs to control compatible equipment. The operator can view process values, change permitted settings and respond to alarms through the touchscreen without using a separate HMI and PLC.
High-speed inputs and pulse outputs support applications that require pulse counting or pulse-based commands. Ethernet, serial and CANopen communications allow data exchange with compatible devices. Actual I/O behavior, signal ranges and communication mappings depend on the selected configuration and application program.
Role in a Harmony SCU Machine Control Architecture
The HMISCU6B5 serves as both the local operator interface and the embedded controller. It processes field inputs, executes programmed logic, updates the touchscreen and exchanges data with compatible equipment through its communication interfaces.

Installation and Maintenance
- Verify the model reference: Confirm HMISCU6B5 and its mixed digital/analog I/O configuration before installation.
- Check the panel opening: Prepare the specified 22 mm mounting hole and confirm that the panel arrangement suits the mounting system.
- Inspect the installation location: Ensure that the panel provides suitable access to connectors and adequate ventilation.
- Confirm the power supply: Provide a suitable 24 V DC source within the permitted voltage range and apply the required circuit protection.
- Isolate power before wiring: Disconnect power before installing or removing field wiring.
- Review the I/O assignment: Match each digital or analog signal to the correct terminal and configured program address.
- Verify analog signal compatibility: Check sensor type, signal range, wiring method and channel configuration before connecting analog devices.
- Check output-load requirements: Confirm that connected loads remain within the controller’s output ratings; use suitable interface devices where necessary.
- Verify communication wiring: Check Ethernet, serial and CANopen connections against the selected protocol and connected-device requirements.
- Configure the application: Use compatible engineering software to load or develop the control logic, HMI screens and communication settings.
- Test I/O and display functions: Verify analog readings, digital transitions, output behavior, touchscreen commands and alarms under controlled conditions.
- Record the configuration: Document the program version, signal assignments, communication settings and maintenance actions for future servicing.

Technical FAQs
How is the HMISCU6B5 different from the HMISCU6A5?
Both models use a 3.5-inch Harmony SCU touchscreen platform. The HMISCU6B5 adds analog input and output capabilities, including temperature-input support, while the HMISCU6A5 uses a digital-I/O configuration. The correct model depends on the signals and control functions required by the application.
What analog capabilities does the HMISCU6B5 provide?
The HMISCU6B5 has four analog inputs and two analog outputs. The input channels support configured analog measurement functions, including temperature measurement, while the outputs can provide analog control signals within their specified operating ranges.
Which software is used to configure the HMISCU6B5?
The controller’s original product documentation identifies SoMachine as its programming software. Before creating or modifying a project, verify that the installed engineering software version supports the device and the functions required by the application.
Can the HMISCU6B5 replace a separate HMI and PLC?
It can combine those functions in a compact system when the required I/O, processing, communication and control functions fit the controller’s capabilities. Applications needing additional I/O, specialized motion control or functions outside the unit’s supported configuration may require separate or additional automation hardware.
