AX-S4 MMS ("access for MMS") is a complete IEC 61850 interface for host applications. AX-S4 MMS supports both IEC 61850 client and server capabilities to provide everything needed to interface with any Windows application supporting OPC and/or DDE interfaces.  AX-S4 MMS brings real-time data from IEC 61850 and UCA® 2.0 intelligent electronics devices (IEDs) such as RTU, protection relays, meters, and load tap changers to the desktop.

Useful for substation automation computers needing access to data in IEC61850 IEDs, testing/configuration of IEC 61850 devices, and for interfacing with non-IEC 61850 devices.
