Control Systems Equipment Control Systems

Overview

The equipment control systems provided by DIASYS Netmation enable the safe and efficient operation of air conditioning equipment and utility equipment in plants and buildings.

In addition, when new equipment is added or changes are made to equipment operation, the customer can make their own modifications to the system, leading to lower system modification costs.

Features

Energy-saving Operation through Various Control Functions

Optimum energy-saving operation for each type of equipment is achieved with the use of schedule control, demand control and automated control features.

Improved Safety and Efficiency

Lighting, heat sources, air conditioning equipment, utility equipment, power equipment and other subsystems are monitored and controlled in an integrated fashion to achieve safe and efficiency equipment operation.

Integration with Systems from Other Companies

We are able to easily integrate with systems from other companies, allowing different systems to co-exist without incurring special expenses.

Monitoring and Operational Features

Integrated Monitoring

Through integrated monitoring, lighting, air conditioning and other subsystems can be monitored at once.

Based on the acquired operational data, parameters for efficient operation can be fed back into the relevant systems.

Scheduled Start-Stop Control

Equipment such as air conditioning and lighting can be grouped by area and automatically switched on or off based on a predetermined pattern of start-stop times.

Demand Monitoring and Control

Equipment and device cut-off and re-start when the commercial power supply is cut off and subsequently restored can be carried out automatically.

Outage Restoration Control

The amount of electricity being received is calculated and demand predications are made every thirty minutes. When the predicted value has exceeded a pre-determined upper limit, a warning message is displayed, and load cut-off control is implemented based on the priority assigned to each piece of equipment.

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

Forms

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.

Maintenance Support

Data such as equipment operating times and the number of start-ups is added up and displayed for each device as maintenance support data.

A warning message can also be displayed when a control value is exceeded.

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.

MHPS 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.
