Product Positioning
MDS SD4 – Market Demands Increased demand for Ethernet and TCP/IP technology to facilitate the operation and maintenance of SCADA systems Users of radio communications in Utility SCADA are concerned with an increasing “noise floor” and the potential for radio interference in the unlicensed bands (ISM Band WiLAN) Regulatory changes require radio communications with greater spectral efficiency and increased cyber security GE MDS has sold licensed band radios since the first model came out in 1985. We have the most expertise in design of this type of radios. In last 2-3 years there has been a growing concern with interference in the unlicensed band. And a concern with security in general, and specifically with wireless. The concerns with reliability and cost of installing and operating a communications system are also applicable, although they are not new. Tremendous pressure to do more with less personnel. Opportunity for more automation. 25% of the workforce expected to retire in the next 5 years, 50% to retire in 10 years. TCP/IP technology is an enabler of greater control with less effort and much simpler operation and maintenance of communication systems in general, and wireless systems in particular. Critical infrastructure organizations with Private Land Mobile Radio (PLMR) frequencies between 150 MHz and 512 MHz are mandated by the FCC to narrowband in order to improve overall spectrum efficiency. We've heard that many customers are taking this opportunity to analyze their entire communications network in order to build a next-generation system that will allow for their needs today and in the future.

Optimized Communications MDS SD4 and IP/Ethernet Optimized Communications
Frame/Packet/Message Structure Ethernet and IP protocols add information to data payloads to allow communications to occur in layers. Industrial Protocols like Modbus TCP/IP works the same way Eth ICMP data ping Eth IP UDP SNMP data Eth IP TCP FTP data Eth IP TCP MB hdr data Modbus TCP/IP 18 20 8 10 (Size in bytes)
SCADA to RTU Communications All SCADA protocols work with master-slave model Modbus TCP DNP3 over IP Any serial polled protocol encapsulated over IP PC Server SCADA Software RTU#1 RTU#1 Query RTU#1 Query TCP Server Virtual data transfer TCP Client TCP TCP IP IP Eth Eth Actual data transfer The RTU receives the Ethernet frame and extracts the data before processing it Modbus data is encapsulated within TCP/IP/Ethernet frames/packets Ethernet frame Eth IP TCP RTU#1 Query
Wireless Ethernet Bridges A bridge transmits frames at the Ethernet layer level Every wireless bridge works this way PC Server SCADA Software RTU#1 RTU#1 Query RTU#1 Query TCP Client Virtual data transfer TCP Server Eth IP TCP TCP IP Eth W Eth W Eth Ethernet frame Ethernet frame Eth IP TCP RTU#1 Query Eth IP TCP RTU#1 Query Wireless Ethernet frame (80+ bytes) W Eth IP TCP RTU#1 Query

SD4 and IP/Ethernet Data All IP connections terminate locally at the SD radio The transmitting SD extracts RTU data packet content and broadcasts it over-the-air The receiving SD regenerates the TCP/UDP data packet Makes efficient use of the channel, but has limitations SD radios don’t route or bridge Ethernet data, it encapsulates industrial protocols in IP payloads
