What is a remote monitoring and operation system? We explain key points for implementing such a system to help reduce labor costs and improve visibility in factories.

Introduction
The practice of moving around large factories to check instrument and control panels is still common in many workplaces. However, with increasing labor shortages and the need for faster response times, there is a growing demand for systems that allow for equipment status assessment and necessary actions to be taken with fewer personnel.
Remote monitoring and operation systems are designed to address these challenges. By allowing users to check the status of equipment remotely and make necessary setting changes or operation, it becomes easier to reduce manpower, improve visibility, and enable early response to abnormalities.
This page provides a comprehensive overview of remote monitoring and operation systems, including their basics, on-site challenges, key functions, implementation benefits, points to check, and configuration examples, while minimizing technical jargon.
Recommended for people like this
For those who want to reduce load of patrolling and checking factories and equipment.
For those who want to improve the early detection of abnormalities and the visualization of equipment.
For those who want to monitor multiple control panels and equipment at once.
Those considering specific measures for factory DX and labor saving.
For those who want to organize their thoughts on implementing a remote monitoring system.
Issues faced in the field
In conventional operations, it is necessary to move to the control panel every time parameter adjustments or equipment status checks are required. This travel time and the checking process gradually become a significant burden in daily operations.
Furthermore, if an abnormality occurs but goes unnoticed until it is confirmed on-site, delays in initial response can lead to quality loss and prolonged equipment downtime.
Common risk examples
Delays in detecting abnormalities in high-temperature processes result in product loss.
The alarm was not checked promptly during the night, causing the production line to remain shut down until the following morning.
Operations that rely heavily on paper logs and manual transcription can lead to recording errors and information sharing omissions.
What is a remote monitoring and operation system?
A remote monitoring and operation system is a mechanism that connects control devices such as PLCs, controllers, and loggers to office PCs and monitoring terminals via a network.
This makes it easier to check equipment status, monitor trends, check alarms, and change parameter without having to go to the site. By configuration to allow remote operation to the necessary extent, it also leads to improved response speed.
Key points to keep in mind
Monitoring should not only involve "seeing," but also about "making it easier to notice anomalies."
Even with existing equipment, it may be possible to implement the system in stages depending on configuration.
For remote connections, security design, including communication encryption and access rights management, is crucial.
Key Features
①
Remote parameter setting
This system allows you to easily change settings such as temperature, pressure, and flow rate from your PC screen and have those changes reflected in the equipment.
②
Real-time monitoring
You can continuously monitor changes in equipment status using trend graphs and list screens.
③
Alarm notification
In the event of an anomaly, we support early response through on-screen display and notifications.
④
Remote operation
You can remotely start, stop, and switch modes of the equipment, depending on the conditions.
⑤
Automatic data recording
It can accumulate operating history and anomaly history, which can then be used for quality control and analysis.
⑥
Access rights management
Permissions can be managed according to roles, such as view-only, settings changeable, and operation.
Benefits
Reducing load of routine checks
This reduces the number of site visits and makes it easier to consolidate verification work.
Accelerating response to abnormalities
Alarms and status changes can be more easily monitored remotely, facilitating initial response efforts.
Visualization of equipment
This makes it easier to share equipment status and historical data, helping to ensure everyone involved is on the same page.
The effectiveness of the implementation will vary depending on the equipment configuration, operating methods, and integration conditions with existing systems.
Points to check before implementation
What equipment is being monitored? (PLC, controller, recorder, logger, etc.)
Is monitoring sufficient, or is remote operation also necessary?
Can we utilize existing equipment and networks?
What alarm notification method is needed?
Is data storage, quality documentation, and integration with MES and high-order systems necessary?
Can it meet the security requirements that align with internal company rules?

the purpose
The system centrally manages the control parameter of each furnace and collects manufacturing data such as temperature and current.
Expected effects
This makes it easier to set parameter and check operating status from the office PC, leading to improved centralized monitoring of multiple pieces of equipment and better troubleshooting in case of malfunctions.
System Overview and features
- Connect program controllers and network loggers to CISAS/V4 for centralized management. - Supports writing/reading control parameter - A network logger can collect temperature and current data, and MES (Manufacturing Energy Management System) integration is also possible. - The alarm is triggered by the measurement value and notified via the CISAS screen.

Frequently asked questions
Can it be implemented with existing equipment?
Depending on the equipment configuration and communication conditions, it may be possible to configuration in stages while utilizing existing control equipment and loggers.
Are remote monitoring and remote operation the same thing?
They are different. Monitoring involves checking the status, while operation includes changing settings and starting/stopping the system. It is important to design the system by separating the necessary scope.
How should we consider security aspects?
Encrypting communications, managing access rights, restricting connection paths, and ensuring compliance with internal network policies are crucial.
Is it effective even for small-scale facilities?
Yes. Even with a small number of monitored targets, there are cases where implementation can be expected to yield benefits, such as reducing the number of patrols and enabling earlier detection of anomalies.
Summary
Remote monitoring and operation systems are a promising option for improving equipment visibility, reducing manpower requirements, and enabling early response to anomalies. The key is not simply remote viewing, but designing monitoring, notification, operation, and recording systems to suit the specific operational challenges of the site.
If you want to clarify whether it can be applied to your own equipment or to what extent remote operation is necessary, we recommend proceeding with your considerations based on your actual equipment conditions.
