Product Overview
The Schneider Electric HMISCU8B5 is a Harmony SCU HMI controller that combines a 5.7-inch color touchscreen with programmable control functions. It is intended for compact machines and simple process-control systems where an operator interface and embedded controller are needed in one device.
Unlike the HMISCU8A5 digital-I/O model, the HMISCU8B5 combines discrete I/O with analog measurement and output capabilities. This makes it suitable for applications that need to process switch and sensor signals while also monitoring variables such as temperature or other supported analog inputs. Examples include packaging machinery, material-handling equipment and compact process systems.
The controller operates from a 24 V DC supply and includes Ethernet, USB, serial and CANopen communication interfaces. Operators can use the touchscreen to view process values, machine states and alarms, while the controller executes the configured application logic. Its I/O assignments, control program and HMI screens are developed using compatible Schneider Electric engineering software.

Working Principle
The HMISCU8B5 combines operator interaction with programmable control. Digital inputs receive signals from switches and discrete sensors, while analog inputs acquire supported process measurements. The controller executes the application program and updates its outputs and touchscreen according to the configured logic.
For example, a compact process machine may use digital inputs to detect equipment states, analog inputs to monitor a process variable, and digital or analog outputs to control compatible devices. Operators can monitor values and alarms on the touchscreen and adjust permitted settings without using a separate HMI and PLC.
The high-speed input and pulse-output functions support specific counting and pulse-based control tasks. Ethernet, serial and CANopen interfaces allow data exchange with compatible devices. Actual signal ranges, I/O behavior and communication mappings depend on the selected configuration and connected equipment.
Role in a Harmony SCU Machine Control Architecture
The HMISCU8B5 functions as both the local operator interface and embedded controller. It acquires field signals, executes programmed logic, updates the touchscreen and communicates with compatible devices through its available interfaces.

Technical FAQs
How does the HMISCU8B5 differ from the HMISCU8A5?
Both models have a 5.7-inch Harmony SCU touchscreen. The HMISCU8B5 includes analog input and output functions in addition to digital I/O, while the HMISCU8A5 uses a digital-I/O configuration. The appropriate model depends on the field signals and control functions required.
What types of analog signals can the HMISCU8B5 handle?
The controller supports analog measurement and temperature-input functions, along with analog outputs. The supported signal types and ranges depend on the input or output function and its configuration, so the wiring and channel settings must match the connected device.
Can the HMISCU8B5 communicate with a CANopen device and an Ethernet device in the same application?
The controller includes both CANopen and Ethernet interfaces. Whether both can be used for a particular application depends on the required network arrangement, supported protocols and application configuration.
What should be checked when replacing an HMISCU8B5 screen or rear module?
Confirm whether the replacement is the HMIS85 screen module or the HMISBC rear module, and ensure it matches the intended analog-I/O controller configuration. The screen and rear module must form a supported combination for the required controller functions.
