HMI System Research

Give operators a clear view of machine state and recovery.

HMI systems provide the visual interface between operators and automated equipment. They display machine state, process values, alarms, recipes, counters, manual controls, diagnostics, and recovery instructions so production teams can understand and interact with the system.

HMI Systems / Control DiagramCTL-03 / CONTROL SYSTEM
01 / Control Structure

Control decisions should make machine behavior predictable.

Inputs, operator interaction, motion commands, feedback, interlocks, alarms, diagnostics, and recovery all affect how reliably production equipment responds.

02 / Planning Criteria

Good controls reduce uncertainty on the plant floor.

Operators and maintenance teams need clear state information, reliable sensing, stable motion, and diagnostic paths that make faults easier to understand and recover.

CRIT-A

Information Hierarchy

Critical status, active faults, production rate, and next required action should be easier to find than secondary detail.

CRIT-B

Alarm Design

Alarms should identify the condition, affected area, likely cause, and safe recovery path without flooding the operator with low-value messages.

CRIT-C

Recipe Control

Product-specific settings should be grouped, validated, access-controlled, and transferred consistently to the machine logic.

CRIT-D

Recovery Guidance

Clear prompts, interlock status, permissives, and manual controls can reduce mean time to recover after routine production faults.

03 / Technical Views

Visualize how commands and feedback move through the system.

These diagrams focus on the specific control relationships behind operator interfaces, sensing, coordinated motion, and closed-loop servo behavior.

Alarm structure.

Operator interfaces work better when alarms are prioritized and tied to a clear cause and recovery path.

Machine states.

A well-designed HMI makes transitions between stopped, ready, running, faulted, and recovery states easy to understand.

04 / Industrial References

Relevant controls and automation resources.

External references are selected from the approved TempoJS manufacturing link inventory and matched directly to each controls topic.

Tempo Principle

An HMI should help people understand what the machine is doing and what to do next. State visibility, alarm quality, recipe control, diagnostics, and recovery guidance all support production uptime.
