Edge Devices for Industrial Machine Monitoring (Industrial Edge Computing Guide)
Edge Devices for Industrial Machine Monitoring
Industrial automation systems are becoming increasingly connected as manufacturers adopt modern monitoring technologies. Machines are no longer isolated pieces of equipment; they are now part of integrated production networks that allow engineers to monitor performance, detect faults, and improve efficiency.
Industrial equipment such as roll forming machines, steel processing lines, CNC machining centers, packaging machines, and automated production systems are typically controlled by Programmable Logic Controllers (PLCs).
While PLCs control machine operations, modern monitoring systems require additional hardware capable of collecting, processing, and transmitting machine data to remote platforms.
This is where industrial edge devices play an important role.
Edge devices collect machine data directly from industrial equipment and process it locally before sending it to monitoring systems, cloud platforms, or remote engineers.
What Is an Industrial Edge Device?
An industrial edge device is a computer or networking device installed close to the machine that collects and processes machine data.
The term edge refers to the “edge of the network,” meaning the location where data is generated.
Instead of sending raw machine data directly to remote servers or cloud platforms, edge devices process the information locally.
This reduces network traffic and allows faster data analysis.
Edge devices act as intermediaries between:
- PLC controllers
- machine sensors
- industrial networks
- cloud monitoring platforms
They help transform machine data into useful operational information.
Why Edge Devices Are Used in Industrial Monitoring
Traditional industrial systems relied on centralized monitoring platforms where all machine data was transmitted to remote servers.
However, as factories generate larger amounts of data, this approach can create several challenges.
Edge devices help solve these problems.
Reduced network traffic
Edge devices process data locally, reducing the amount of data transmitted to remote systems.
Faster response times
Local processing allows machines to respond quickly to operational changes.
Improved reliability
Edge devices allow monitoring systems to continue operating even if cloud connectivity is temporarily unavailable.
Better data filtering
Only important information is transmitted to remote monitoring platforms.
These advantages make edge devices an essential component of modern industrial monitoring systems.
How Edge Devices Work in Machine Monitoring Systems
Edge devices are installed near machines and connected to industrial control systems.
Typical connections include:
- PLC controllers
- industrial sensors
- machine communication networks
A typical architecture may include:
Machine control layer
PLC controller
HMI panels
servo drives
industrial sensors
Edge processing layer
industrial edge device
Connectivity layer
factory network or cellular router
Remote monitoring layer
cloud monitoring platform
engineering workstation
The edge device collects data from the machine and processes it locally before sending relevant information to monitoring systems.
Types of Data Collected by Edge Devices
Edge devices can collect and analyze many different types of machine data.
Common examples include:
- machine operating status
- production speeds
- system alarms
- sensor measurements
- motor performance data
- energy consumption
- equipment utilization
This information allows engineers to monitor machine performance and identify potential problems.
Edge Devices and PLC Communication
Edge devices communicate with PLC systems using industrial communication protocols.
Common communication methods include:
Industrial Ethernet protocols
Many modern PLCs communicate using Ethernet-based protocols.
Fieldbus communication
Some machines use industrial fieldbus networks.
Serial communication
Legacy PLC systems may use serial communication protocols such as RS232 or RS485.
Edge devices can collect data from these communication systems and convert it into standardized monitoring data.
Example: Edge Monitoring for Roll Forming Machines
Roll forming machines used in steel manufacturing often require continuous monitoring.
These machines control processes such as:
- coil feeding systems
- roll forming stations
- punching systems
- hydraulic cutting systems
Edge devices installed in the machine control cabinet can collect operational data such as:
- servo motor speeds
- encoder length measurements
- machine production rates
- hydraulic pressure levels
This information can then be transmitted to remote monitoring systems for analysis.
If abnormal machine behavior is detected, engineers can investigate the issue remotely.
Edge Devices and Predictive Maintenance
One of the most important applications of edge computing is predictive maintenance.
Predictive maintenance systems analyze machine data to detect signs of potential equipment failure.
Edge devices can process data from sensors and machine components such as:
- vibration sensors
- temperature sensors
- motor current measurements
- hydraulic pressure sensors
By analyzing this data locally, edge devices can detect abnormal operating conditions.
Alerts can then be sent to maintenance teams before equipment failures occur.
Edge Devices and Smart Factory Systems
Smart factories rely on connected machines that continuously transmit operational data.
Edge devices play a critical role in these systems by acting as the data collection point for machine monitoring.
They support modern automation technologies such as:
- industrial Internet of Things (IIoT) platforms
- real-time machine dashboards
- centralized production monitoring
- predictive maintenance analytics
Edge computing allows factories to process large amounts of data efficiently.
Advantages of Industrial Edge Devices
Industrial edge devices provide several important advantages.
Real-time data processing
Local processing allows faster response to machine conditions.
Reduced network bandwidth
Less data must be transmitted to cloud platforms.
Improved reliability
Edge systems continue functioning even during network interruptions.
Better data filtering
Only relevant machine data is transmitted to monitoring systems.
Enhanced cybersecurity
Local processing can reduce exposure to external networks.
These benefits make edge devices essential for modern industrial monitoring.
Key Features to Look for in Industrial Edge Devices
When selecting an edge device for machine monitoring, several important features should be considered.
Industrial reliability

Choosing the right edge device ensures reliable machine monitoring.
Integrating Edge Devices with Remote PLC Access
Edge devices can also work alongside remote PLC access systems.
While PLC remote access allows engineers to connect directly to machine controllers, edge devices collect continuous machine data.
Together, these technologies allow factories to:
- monitor machine performance continuously
- analyze machine data remotely
- diagnose equipment problems quickly
- improve production efficiency
This combination creates powerful industrial monitoring systems.
