Code Sample Descriptions

Hello World Button Script

system.gui.messageBox("Hello World from Ignition Perspective!")

A simple Python script bound to a button's onClick event in Perspective.

Let’s Try →

Start/Stop Control with Perspective

if self.custom.mode == "Start":
    system.tag.writeBlocking(["[default]Motor/Start"], [True])
else:
    system.tag.writeBlocking(["[default]Motor/Stop"], [True])

A Perspective button script writing to a PLC tag when clicked.

Let’s Try →

Update Numeric Display

value = system.tag.readBlocking(["[default]Tank/Level"])[0].value
self.getSibling("NumericDisplay").props.text = str(value)

Updates a numeric display component with a tag value in Perspective.

Let’s Try →

Toggle Light Indicator

current = system.tag.readBlocking(["[default]Light/On"])[0].value
system.tag.writeBlocking(["[default]Light/On"], [not current])

Toggle a boolean tag controlling a light indicator from a button click.

Let’s Try →

Slider Control for Motor Speed

speed = self.props.value
system.tag.writeBlocking(["[default]Motor/Speed"], [speed])

Bind a slider in Perspective to a motor speed tag.

Let’s Try →

Log Button Clicks

from datetime import datetime
log = system.tag.readBlocking(["[default]ButtonLog"])[0].value
log += f"Clicked at {datetime.now()}\n"
system.tag.writeBlocking(["[default]ButtonLog"], [log])

Append a log entry every time a button is clicked in Perspective.

Let’s Try →

Dynamic Label Update

status = system.tag.readBlocking(["[default]Machine/Status"])[0].value
self.getSibling("StatusLabel").props.text = f"Status: {status}"

Change a label text dynamically based on a tag value.

Let’s Try →

Set Multiple Tags

tags = ["[default]Motor/Start", "[default]Motor/Speed"]
values = [True, 50]
system.tag.writeBlocking(tags, values)

Write multiple tag values simultaneously from a script.

Let’s Try →

Alarm Acknowledge Button

alarmPath = '[default]Tank/HighLevel'
system.alarm.acknowledge(alarmPath)

Acknowledges an alarm in Perspective when a button is clicked.

Let’s Try →

Fetch and Display PLC Data

tags = ["[default]Tank/Level", "[default]Pump/Status"]
values = [v.value for v in system.tag.readBlocking(tags)]
self.getSibling("Table").props.data = [{'Tag': t, 'Value': v} for t, v in zip(tags, values)]

Read multiple PLC tags and display values in a Perspective table.

Frequently Asked Questions about Ignition-perspective

What is Ignition-perspective?

What are the primary use cases for Ignition-perspective?

Web/mobile SCADA HMIs. Real-time dashboards for plants and utilities. IIoT dashboards with MQTT/Sparkplug B. Industrial mobile apps for technicians. Multi-site enterprise visualization

What are the strengths of Ignition-perspective?

Completely browser-based runtime. Runs on any device with no installation. High-performance real-time updates. Perfect for enterprise-level SCADA. Massive customization with scripts + bindings

What are the limitations of Ignition-perspective?

Requires Ignition Gateway server. Learning curve for bindings & views. Mobile sensors require permissions. No direct PLC programming (only visualization). Browser performance varies on low-end devices

How can I practice Ignition-perspective typing speed?

CodeSpeedTest offers 10+ real Ignition-perspective code examples for typing practice. You can measure your WPM, track accuracy, and improve your coding speed with guided exercises.
