Features

1. Promoting the IoT of control equipment

• The following standard I/F are equipped in order realizing IoT. It is easily possible to be IoT device just by connecting.

[Equipment side I/F]

• Serial I/F（RS422/RS485）

• 8bit parallel I/F（for smart meter）

• Ethernet

[IP side I/F]

* I/F other than above mentioned will be supported sequentially（LON, Device-Net etc.） and it is also possible to support customed I/F.

2. Long-distance communication is capable

• Since the communication using PLC technology is converted IP transmission by power cable or coaxial cable is possible, that makes possible to long-distance communication of 2000m or more between devices.

3. I/O control is possible by using option

• The sensor and the actuator can be controlled directly from this device. In addition, since16bit microprocessor is equipped for I/O control, various I/O controls are possible.

[Equipped I/O]

• Digital I/O : ON/OFF,PWM

• Analogue I/O : ADC, DAC

4. Monitoring the operating status and setting the device up form web is possible

• Remote setting/displaying status is possible even if it is placed in area where work is difficult, such as behind the celling etc.

Case study: IoT application of meter reading system

• IP conversion of smart meter data.(using the device I/F:9bit Data Module, IP I/F:PLC Module)

• After receiving the calorimeter signal by GPIO and process the data, it is converted to IP.(using the expansion I/O module)

• Inputting collection data/reading meter to the PC then meter reading operation is performed by online.

• Store the collecting data from each meter to the data server then these data can be reused as a big data.

• ⇒ IP conversion of meter reading system makes reducing the cost of meter reading operation, and energy serving control is possible by reusing collected data.
