The Multilin D20MX™ represents the next innovation in cyber secure RTU technology. The D20MX is built upon the field-proven, reliable Multilin D20 technologies and applies the latest industry proven security standards. Multilin D20MX continues the tradition of high reliability automation and control through extreme quality and long term product availability characteristic of the Multilin D20 products.

Reduce legacy D20 RTUs upgrade cost by over 50% through backwards compatibility with earlier versions of the Multilin D20 Substation Controllers and D20 peripheral modules

Minimize operation and maintenance cost of existing D20 based SCADA infrastructure leveraging existing designs, processes and infrastructure

Comply with NERC-CIP requirements through application of native cyber security features built into the D20MX Substation Controller

Simplify implementation and operation of NERC-CIP architectures using the D20MX open standard based cyber security features

The Multilin D20MX Substation Gateway collects, filters, and sorts data from a wide range of intelligent devices (RTUs, relays, meters) in the substation. The D20MX preserves original data time stamp for accurate sequence of event allowing data from large diverse geographic regions and time zones to be analyzed in extreme detail. Data can be presented simultaneously to multiple SCADA hosts. The D20MX comes with a built-in suite of protocols and security applications to facilitate integration with various substation devices and SCADA hosts.

The Multilin D20MX provides a cost effective alternative to upgrades of legacy D20 RTUs. This means that the investments made in GE automation systems keep paying dividends beyond their originally projected end of life. Simply replace the failed or end of life Multilin D20 processor module with a Multilin D20MX and migrate the device configuration to extend the life of the existing D20 Controller and add cyber security features for integration into NERC-CIP environments. As technology changes with market demands, GE continues to invest in a partnership with their customers through advanced modular design principals.

The Multilin D20MX supports a comprehensive set of security functions to allow a seamless integration with existing IT department policies. Built-in cyber security features such as Remote Authentication Dial-In User Service (RADIUS), Role Based Access Control (RBAC), and user activity logging, provide a complete security toolkit required to achieve NERC-CIP compliance.

The Multilin D20MX is a 6U VME bus embedded single board computer powered by a 567 MHz power PC CPU pin-for-pin compatible unit with existing D20 VME and non-VME D20 Processors.

Previous generations of D20 RTUs required add on system components and software to support Ethernet communications and optional memory expansion. The new D20MX is equipped by default with integrated memory, 10/100/1000BASE-TX or 100BASE-FX IEEE 802.3 compliant communications and a core load firmware with a comprehensive set of key Substation Automation applications.
