Inquiry (采购产品): SCADA system Dear Sir, We are preparing a specification for SCADA (Supervisory Control and Data Acquisition) system for our client. The proposed SCADA system shall have the following connectivity: (i) The proposed new SCADA system shall be connected to an existing SCADA system through OPC over Ethernet LAN. The new SCADA server will exchange real time data with an existing SCADA server through OPC. (ii) The proposed new SCADA system shall be connected to existing Substation Automation System (SAS) servers through OPC over Ethernet LAN. The new SCADA server will exchange real time data with SAS server through OPC. (iii) The proposed new SCADA system shall be connected to existing Level-1 process automation servers through OPC over Ethernet LAN. The new SCADA server will exchange real time data with existing Level-1 process automation servers through OPC. Can you give some idea about the proposed solution (for connectivity over OPC) to be considered, licensing details and type of OPC connectivity required for the above system. Hope to receive reply from you at the earliest. Thanks & Regards R. N. Chakrabarti **** Hidden Message ***** Rajendra Nath Chakrabarti 700013 IND Company: M. N.
