This network topology shows how AVE or AWR is integrated into the SCADA system.
The power quality analyzer (PQA) measures power quality variables and transfers this information directly through either wireless or wired network to the AVE or AWR units. Information from the PQA is also obtainable through WEB interface or at local operator stations.
It is possible to have several power quality analyzers in the system. This could be suitable if the operator want’s to monitor specific switchboards.
The PQAs are able to attach both analog and digital IO modules for feedback and control of equipment. This could be used to monitor and control machines. For example, it can be utilized to shut down machines based on electricity spot price or power quality situations.
Standard communication protocol is Modbus TCP/IP. Both wired and wireless network are possible depending on wireless range limitations or customer preferences.
Remote support is possible through WEB interface. If problems or questions arise regarding power quality analyzer, AVE or AWR, the support help line can assist. Remote support is also used for software upgrades on units.
The units are equipped with industrial WAN router with optional 4G for easy web access through cellular network.
