Overview

This is a reference page gathering the meanings of status badges, icons, and colors displayed throughout the Platform screens. Refer to this document if you are unsure of the meaning of a color or code encountered during operation.

This document is a status code reference, mapping codes displayed in the following screens:

Dashboard · Daily Statistics · Connection Management · Equipment
Alarm · Diagnostic · Work Order

Alarm Priority

A 3-level scale indicating the severity of an alarm.

Code	English	Color	HEX	Description	Recommended Action
`INFO`	Info	Green	`#5eb561`	Informational alarm	No immediate action required, for reference
`WARN`	Warning	Orange	`#eb7f0a`	Attention required	Monitor trend, prepare for inspection if approaching threshold
`ERROR`	Critical	Red	`#d9534f`	Immediate action required	Inspect asset or notify system administrator

Alarm Band and Priority Mapping

Alarm bands (threshold ranges) are automatically mapped to priorities.

Alarm Band	Mapped Priority
`NORMAL`	No Alarm
`HIGH` / `LOW`	`INFO` (Info)
`HIGH-HIGH` / `LOW-LOW`	`WARN` (Warning)
`TRIP-HIGH` / `TRIP-LOW`	`ERROR` (Critical)

Alarm Active/Acknowledge Status

Status	Value	Meaning
Active	On	Alarm Active (Occurring)
Active	Off	Alarm Cleared (Recovered)
Acknowledge	Acknowledged (`ACKED`)	Someone acknowledged — one acknowledgement per alarm
Acknowledge	Unacknowledged (`UNACKED`)	No one has acknowledged yet

Even if an operator has acknowledged an alarm, it will still be displayed as an active alarm on the screen if it has not yet recovered.

Alarm Hidden Status

Hidden occurrences are recorded separately, not in the alarm list — Hidden · Suppressed · Out of Service.

Code	Screen Text	Meaning
`SHELVED`	Shelved	Alarm hidden for a duration set by the operator (ISA-18.2 shelved)
`SUPPRESSED_BY_DESIGN`	Suppressed	Alarm suppressed by equipment status due to planned maintenance/repair (ISA-18.2 suppressed by design)
`OUT_OF_SERVICE`	Out of Service	Alarm removed from service by administrator (ISA-18.2 out of service)

Alarm Clearing Reason

Code	Screen Text
`RETURN_TO_NORMAL`	Normal Recovery
`BAND_CHANGED`	Changed to Different Band
`CONFIG_DISABLED`	Alarm Setting Disabled
`CONFIG_DELETED`	Alarm Setting Deleted
`RECOVERY`	Restart Recovery
`OUT_OF_SERVICE`	Out of Service — Not Resolved

Diagnostic Level

The severity of system diagnostic logs displayed on the Diagnostic screen.

Code	English	Color	HEX	Description
`INFO`	Info	Blue	`#5bc0de`	Normal operation information (Start/Stop notifications, etc.)
`WARN`	Warning	Orange	`#f0ad4e`	Potential issue, monitoring required
`ERROR`	Critical	Red	`#d9534f`	Critical situation, immediate inspection required

Screen colors may vary slightly depending on the operating environment's theme settings.

Communication Connection Status (OPC/Edge)

The data reception status of OPC servers and Edge devices is determined based on the last reception time.

Code	English	Color	HEX	Threshold	Description
`OK`	Connected	Green	`#2e7d32`	< 10 min	Normal data reception
`WARN`	Delayed	Orange	`#e65100`	10 min ~ 60 min	Data not received, caution
`ERROR`	Anomaly	Red	`#b71c1c`	60 min ~ 24 hours	Not received for over 1 hour
`DISCONNECTED`	Disconnected	Gray	`#888`	> 24 hours	Not received for over 24 hours
`UNKNOWN`	Unobserved	Light Gray	`#ccc`	—	No final reception history

Thresholds of 10 min, 60 min, and 24 hours are values determined by StatusThresholds. In some older screens, such as the asset tree legend, OK is written as "Normal Connection" and UNKNOWN as "Disconnected" — these are the same statuses with different names.

Quick Identification Tips

Scenario	Meaning
Immediately after new OPC registration	`UNKNOWN` (Never received)
Normal collection operation	`OK`
Brief interruption (Network/Restart)	`WARN`
Interruption for over 1 hour	`ERROR` (Check Connection Management immediately)
Interruption for over one day	`DISCONNECTED` (Inspect device/network)

Communication Latency Status (OPC Latency)

There are two sets of criteria for latency. The one applied depends on which screen you are viewing.

① For Status Determination — Average Latency

This criterion is used when assigning asset health status (StatusEvaluator).

Code	English	Color	Threshold (Avg Latency)	Description
`OK`	Normal	Green	< 1 sec	No response delay
`WARN`	Delayed	Orange	1 sec ~ 10 sec	Response delay occurring
`ERROR`	Critical Delay	Red	> 10 sec	Severe response delay
`UNKNOWN`	Unknown	Gray	—	No latency measurement data

② For Trend Charts — Maximum Interval Latency

The Communication Latency Status Trend chart on the Connection Status screen is calculated by the maximum latency of that time interval (max_latency), not by the above criteria.

Bar	Threshold (Max Interval Latency)
🟢 Normal	< 10 sec
🟠 Delayed	10 sec ~ 60 sec
🔴 Critical Delay	> 60 sec

Tooltips above the chart show values from ①

While the ⓘ help text for that chart says "Average Latency < 1 sec / 1~10 sec / > 10 sec", the calculation for the bars is based on ② (Max 10 sec/60 sec). The tooltip number and the bar follow different criteria, so interpret the chart using ②.

A connection with an average of 3 seconds appearing as green on the chart is not a malfunction but due to this difference.

Health Status (Site/Area/Line/Equipment)

Health status by hierarchy. This is determined by the highest level alarm occurring under the respective hierarchy.

Code	English	Color	HEX	Description
`NORMAL`	Normal	Green	`#3d8b40`	No alarms
`WARN`	Warning	Orange	`#eb7f0a`	1 or more Warning alarms
`ERROR`	Danger	Red	`#d9534f`	1 or more Critical alarms
`UNKNOWN`	Unknown	Light Gray	`#ccc`	No evaluation data (e.g., immediately after new registration)

Determination Logic: 1+ Critical alarm → ERROR, 1+ Warning alarm → WARN, Otherwise → NORMAL. If no evaluation exists → UNKNOWN.

Connection Status Aggregation (Hierarchical Unit)

The connection status of a hierarchy (Site/Area/Line/Equipment) is determined by aggregating the status of all OPCs/Edges belonging to that hierarchy.

Code	English	Color	Description
`NORMAL`	Connected	Green	All subordinates are `OK`
`WARN`	Delayed	Orange	1 or more subordinates are `WARN`
`ERROR`	Anomaly	Red	1 or more subordinates are `ERROR`
`DISCONNECTED`	Disconnected	Dark Red (`#4a0e0e`)	1 or more subordinates are `DISCONNECTED`
`UNKNOWN`	Unobserved	Light Gray	No evaluation data for subordinates

Determination Logic (High Priority → Low): DISCONNECTED → ERROR → WARN → NORMAL → UNKNOWN.

System Health Status

The overall health status of the Platform, determined by diagnostic log counts.

Code	English	Color	Description
`NORMAL`	Normal	Green	No diagnostic logs
`INFO`	Info	Blue	Only informational diagnostics occurred
`WARN`	Warning	Orange	Warning diagnostics occurred
`ERROR`	Danger	Red	Critical diagnostics occurred, system inspection required

The Load Watchdog operates a separate 3-stage state machine (HEALTHY/DEGRADED/CRITICAL) for the Dashboard Health Rail and Diagnostic.

Watchdog Status	Meaning	Issuance
`HEALTHY`	Normal Load	(1 line recorded upon recovery)
`DEGRADED`	Threshold 1 exceeded for 30s+	1 line of diagnostic log (WARN)
`CRITICAL`	Threshold 2 exceeded for 30s+	1 line of diagnostic log (ERROR)

Health Check Status (Infrastructure Components)

Displayed in the "Infrastructure" section of the Dashboard Health Rail.

Result Codes

Code	English	Meaning
`NORMAL`	Normal	Component operating normally
`ABNORMAL`	Abnormal	Component anomaly detected
`UNKNOWN`	Unknown	Health check result not received

Health Check Targets (Based on Dashboard Health Rail Labels)

Label	Role
In-Memory Cache	Operational data cache
WebSocket	Real-time push channel
MQTT	MQTT message channel
KAFKA	KAFKA message channel
Event Store	Event/Time series permanent storage
Time Series Engine	Time series data processing engine

Component labels are the names displayed exactly as they appear on the operational screen. Labels remain consistent even if internal implementations change.

Equipment Operation Status (OEE)

Equipment operation status based on OEE (Overall Equipment Effectiveness).

Code	English	Color	HEX	Description
`RUN`	Operating	Green	`#15803D`	Normal production in progress
`IDLE`	Idle	Orange	`#D97706`	Standby (Lack of raw materials, awaiting order, etc.)
`FAULT`	Breakdown	Red	`#B91C1C`	Non-operating due to equipment failure/anomaly
`STOP`	Stopped	Dark Gray	`#374151`	Intentional stop by operator
`SETUP`	Setup	Blue	`#1D4ED8`	Preparation/Setup (Mold change, warming up)
`PLANNED_STOP`	Planned Stop	Blue	`#1D4ED8`	Planned stop (Lunch, periodic inspection, holiday)
`PLANNED_START`	Planned Start	Blue	`#1D4ED8`	Planned operation start
`DOWN`	Non-operating	Gray	`#4B5563`	Non-operating status
`UNKNOWN`	Unknown	Gray	`#888`	Status unknown

Operating/Non-operating Classification

Classification	Included Codes
Operating	`RUN`, `SETUP` (Production Prep), `PLANNED_START`
Non-operating	`IDLE`, `FAULT`, `STOP`, `PLANNED_STOP`, `DOWN`, `UNKNOWN`

OEE Availability is calculated as Operating Time ÷ Planned Operating Time (Planned Stop is excluded from the denominator).

Work Order Status (Full Lifecycle)

The state machine for WorkOrders. These five are the values actually stored.

Two more statuses are visible on the Work Order screen

The Work Order List shows 7 types by adding Delayed and Cancelled. These two are not stored statuses but are calculated by the screen comparing the standby status with the current time. Determination rules are in that document.

Code	English	Color	HEX	Description
`WAIT`	Standby	Gray	`#888`	Awaiting work order (Default status after creation)
`START`	In Progress	Green	`#15803D`	Work order being executed
`PAUSED`	Paused	Orange	`#D97706`	Work temporarily suspended (Can be resumed)
`END`	Completed	Dark Gray	`#374151`	Work normally completed
`ABORTED`	Aborted	Dark Red	`#7f1d1d`	Work ended abnormally (Quality issue, line isolation, etc.)
