Hi friends,
Our company is searching the best choice to carry out a system able to manage and control electrical consumption in several cities.
By studying several options we have found Echelon's NES system is "maybe" the optimal solution to our needs although we'd like to have other options regarding protocols and energy meters (http://www.echelon.com/metering/architecture.htm)
The schema: [SCADA <-> Data Concentrators <-> Energy Meters] is what we are whising and Echelon"s system has all this but... we have some doubts we want to clarify before in order to choice this system:
1) Is there any other energy meters (EM) brand able to talk Modbus or LonWorks by using PowerLine Communication (PLC) as mean of transport
directly (without transceivers/converters). We already know there is EMs with Modbus capacity but we haven't found one able to use PLC natively.
Although we don't have problems to use Echelon's EMs (it looks excelent), we just want to know and compare other similar EMs.
2) Using the Echelon's Data Concentrator (DC) showed on above link, how fast and reliable is this device (DC-1000) by using PLC to communicate to EMs & SCADA?. Is there any other device from different manufacturer able to do the same?.
3) Although Echelon has its own software for this kind of app (NES software) whe plan to use a commercial SCADA instead and OPC as protocol to read our DCs, my question is: what are the best OPC servers currently to read/write devices via LonWorks?
Thanks to everyone.
