Device function description:
This device was designed to comfortable data collection from electricity meters and to transfer the data to the supervisory control system. It is possible to process the data on a PC equipped with special software. For data collection most customers used impulse count system, where every impulse has its weight, for example 10kWh per every impulse.
Disadvantage of this system is its inaccuracy caused by:
Impulse lose caused by wire line interruption
Impulse lose caused by power cut/restart/shutdown of the control system or PC.
Within every intervention to the electricity meters or currency transformers it is necessary to respect change of constant and weight of the impulses.
This can be simply solved by using direct OBIS registry reading from the electricity meters, when data in control system is exactly the same as data that are shown on display of the device, so no disproportion is occurring.
Gateway operate independently and provide followings services:
Typical system configuration
data logger Protocol (special www.abidata.be)
Modbus RTU slave (supervisory DCS, RS232/RS485)
Modbus TCP slave (supervisory DCS, Ethernet)
INMAT slave protocol
IEC 62056-21 (electricity meter, RS232/RS485)
Accessories – control terminal
As a standard accessory we provide control terminal, which allows to set basic system parameters and last but not least to watch communication with the electricity meters in real time.
Terminal provides setting these parameters:
date and time , enable/disable of time synchronization
for Modbus interface: address and speed
for IEC interface: address, speed, password, par1, par2…
Configuration is saved in XML form and you can load it from the file, change it and save those changes. It is possible to load whole configuration into the device. You can also change parameters to be loaded into the electricity meters even when it is running.
