Equipment Control Systems

Control Systems



Developed for power plants, DIASYS Netmation handles monitoring and control at various large-scale facilities with its renowned high reliability, stability, functionality, and the ease of engineering and operation Mitsubishi Power has refined as a system user.


High Reliability that Caters to Large-scale Facilities

DIASYS Netmation supports system redundancy as standard and can be configured to provide a highly reliable system for large-scale facilities.

Online Maintenance that Gives Highest Priority to Equipment Operation

System modifications can be carried out online while the equipment is still operational, enabling system operation that prioritizes facility uptime. In addition, customers themselves can perform system modifications, allowing for lower modification costs.

System Configuration

Equipment Control System Configuration Diagram

Basic Configuration

Operator Station (OPS) This equipment is used for monitoring and operation. This carries out monitoring and operation by displaying graphics and trends, showing alarms, and so on.
Accessory Station (ACS) This equipment is used for data collection. Manufacturing data collected from on-site manufacturing equipment is managed, and the data is output into forms.
Engineering & Maintenance Station (EMS) This equipment is used for maintenance. Maintenance tasks such as the creation and modification of logic and graphics screens, as well as system setup are performed.
Multiple Process Station (MPS) Control equipment that performs I/O with instrumentation and other equipment installed on-site at the plant, as well as automated plant control and various computational processing.


Monitoring and Operational Features

Online Monitoring

The collected data can be monitored in real-time, providing swift data analysis in the event of a breakdown. In addition, as the system allows online maintenance to be performed while the equipment is still running, the system can be efficiently updated based on data analysis from testing facilities and elsewhere.

Alarm Display

When an equipment malfunction occurs, a real-time alarm is displayed on the monitoring screen, supporting early discovery of abnormalities. A per-device history of alarm triggering and restoration can also be displayed.

Alarm Notification

Through an alarm notification feature that works over the Internet or PHS communications, even when an operator is away from the site, they can quickly take action to address an equipment fault.

Trend Display

Equipment operational status and fault signals can be managed through a trend display.
Real-time trends covering periods of up to 24 hours and historical trends for up to 30 days can be displayed.

Management Support Features

Form Features

With daily, weekly, monthly and annual reports, forms are managed in the format best suited to the customer. A file containing a list of warning items generated on a monthly basis can also be created.

Optional Features

Energy Visualization Function

With a wide range of monitoring and analysis features including basic unit calculations and energy consumption, CO2 conversion and a comparison of equipment operating statuses with the use of Gantt charts, efficient plant operation and reduced energy consumption is achieved.

Remote Monitoring Function

The Internet-based remote monitoring function allows production status to be verified from a different building inside the plant.
Mitsubishi Power has also developed a communications protocol designed for remote monitoring. Using this protocol, screens can be displayed at the same speed as an on-site Operator Station (OPS), even over an analog telephone line.
