The ELC500 Control Unit enables program-less Ethernet data logging, demand monitoring and control at short intervals of five seconds, and remote equipment monitoring using a Web server. This product allows the incorporation of IoT in your factories and equipment to help optimize energy use and improve productivity.

Contributes to the optimization of energy use by enabling monitoring /
control of power demand and visualization of production information
Data logging through Ethernet
Remote monitoring using Web server
Program-less(Note 1) Ethernet data logging and remote monitoring / control(Note 2) using Web server
1) Settings must be made using Configurator EL500.
2) Web content must be produced using Control Web Creator.
|Depending on the type of information to be displayed on the Web server screen, a program may need to be produced using Control FPWIN Pro7.
|Control Web Creator : For details refer to "Software".
Demand monitoring at intervals of several seconds allows prompt response to sudden load fluctuations
Monitoring intervals and control patterns to meet the demand monitoring needs of users
Demand time span is compatible with constant-cycle demand periods of 15 / 30 / 60 minutes.
IEC demand[Compliance with IEC 61557-12 standard]
Demand monitoring complies with the IEC 61557-12 international standard commonly used for energy-saving measures.
IEC demand (Sliding block interval and Fixed block interval)
Users set the time span for demand calculation to an arbitrary value between 1 to 60 minutes (in increments of one minute). The average power demand within the set span is calculated at the end of the span. [The demand values of active, reactive, apparent, active (export), and reactive (export) power are calculated.]
|Sliding block interval method
|Sliding block interval method The next time span starts "n" minutes later. (Value "n" is arbitrarily set by users.)
|Fixed block interval method
|The next time span starts after completion of the current span.
■Three types of control patterns
Controls loads in three steps according to conductions such as demand values to achieve peak-cut.
Controls a group of loads in a rotation manner to reduce overall power consumption.
Delays the startup timing to reduce inrush power and achieve peak-cut.
Ethernet data logging makes it easy to incorporate IoT in production operations
Collection and storage of operation data of existing equipment using add-on device
Settings must be made using Configurator EL500 (compatible units: Modbus TCP / RTU and MEWTOCOL units).
SD memory card (sold separately) is required for data storage.
PLC's communication program is used for serial communication and storage of equipment operation status data.
|Character string data cannot be managed.
|Maximum data size is four words.
There is no need for a program for serial communication and storage of equipment operation status data.
|Reduces engineering man-hours
|Allows easy change of layout
|Visualization of equipment operation information
Comparison of man-hours reduced by retrofitting(Note)
|Note: When Panasonic products are used.
Extension function for logging of I/O signals, analog data and temperature data
To use the extension function, it is necessary to create a program using Control FPWIN Pro7.
There is no means to obtain equipment operation status information through communication function.
FP7 Expansion Unit enables acquisition of equipment I/O signals, analog signals and temperature information.
|Note: To use the extension function, it is necessary to create a program using Control FPWIN Pro7.

Realizes demand monitoring in large plants
There are certain restrictions such as the maximum number of connectable units.
For use in small stores or for partial demand monitoring
Our previous product featured a small number of control points, and its applications were limited to use in small stores or monitoring of partial demand in factories.
Small- / medium-size factories and large plants
By sharing receivingpoint demand information through the network, entire factory loads can be optimally controlled.
Use of the program function enables collection of data from other manufacturers' units that use different protocols
To use the program function, it is necessary to create a program using Control FPWIN Pro7.
Data cannot be obtained from other manufacturers’ power meters, so receivingpoint data cannot be acquired. Therefore, demand monitoring / control is not possible.
Data can be obtained from other manufacturers’ power meters, so demand monitoring / control is possible.
