Siemens provides various products that can be used to integrate data from the Intelligent Electronic Devices in your substations:

With SICAM PAS (Power Automation System) , regardless of the number and variety of functions, one central database makes sure that every piece of information only needs to be entered into the system once.  This ensures data consistency and minimizes effort.  SICAM PAS also controls and registers the process data for all devices of a substation.

The SICAM StationManager II  is able to integrate a wide array of Intelligent Electronic Devices via legacy or industry standard protocols – both serial and LAN-based.  It is capable of performing various data manipulation tasks including filtering, storing, translating, and executing automatic actions.  Data or pre-processed information can be distributed to remote entities like SCADA control centers or maintenance workstations via legacy or industry standard protocols – both serial and WAN-based, including in encrypted format.
