Free of charge monitoring software
The OPC Server software (for Windows Xp - Vista – 7) allows to easily interface network (RS485 or Ethernet types) equipped with Carlo Gavazzi’s devices via OPC based monitoring platform without any added costs.
Real time data communication from: Eos-Array / Eos-array Lite and Energy Meters: EM21, EM24, EM26, WM5, WM30, WM40 to PC based networks to PC based networks. Data coming from Modbus/RTU or Modbus/TCP devices through RS485/232 or Ethernet network, translated into the OPC standard by means of the OPC-DA Server and made available to any OPC-DA Client (Scada, Historian, Data-Hub, …).

The OPC program is free and you can "download" from the section below (DOCUMENTS AND SPECIFICATIONS)
