The UCA TM in-a-LINUX-box has been successfully demonstrated
at the Substation Initiative Meeting
after the IEEE PES PSRC Meeting
(in San Diego (CA) on January 13, 2000)



The following has been demonstrated:

- Sub-Credit card size PC
- JUMPtec DIMM-Concept
- Embedded LINUX
- Embedded UCA (IEEE TR1550)
- Embedded Web, ftp, telnet server
- 10 Mbps Ethernet (2nd DIMM board today)
- TCP/IP
- Example Web site (as it is stored in the box; viewing XML file requires IE 4.0 or 5.0 and XML Notepad)



GOMSFE Models implemented are:

MMXU (Measurement Unit) some 220 Data Objects
PBRO (Basic Relay Object) some 125 Data Objects
Total number of MMS Variables some 350


MMS/CASM Services Implemented:

Initiate
Indentify
GetNameList
Status
Get Capabilities
Read
Write
GetVarAccessAttributes
GetNamedVariableListAttributes
GetDomainAttributes
FileOpen
FileRead
FileClose
FileDelete
FileDirectory
UnsolicitedStatus
InformationReport/Reporting
Conclude
Cancel
Abort



The UCA Server comprises the following components running under LINUX:

RFC 1006 (Mapping to TCP/IP)
Session
Presentation
MMS encoding/decoding
MMS services
UCA CASM services
UCA GOMSFE Models (some
350 domain specific variables)
Runtime scheduler (Test Application)
Data value simulator (e.g. controls changes of data)


All components are compiled and linked under LINUX GNU compiler:

Software size of EXE file 205 Kbyte
Software size of EXE file under Windows (compiler specific) 350 - 450 Kbyte


Possible Applications are:

  • Gateways
  • Retrofit Kit (saving costs for the installed equipment)
  • Embedded into IEDs (Intellingent Electronic Devices)
  • RTUs (Remote Terminal Units)
  • Tele-control
  • PLCs (Programmable Logic Controllers)
  • PCs (Personal Computers)


Retrofit your installed equipment with seamless communications

The maintenance, integration, and operation cost for installed systems are high at the beginning of their life cycle. Some time down the road they reach a minimum and increase dramatically after the minimum has passed. The reasons for the increase are manyfold and well known. For example, the software used will not be supported and updated any more after let' say twelve years, additional information (for maintenance, diagnostic,...) may not be accessible even if it is available locally in the equipment's computer system. These systems may not be replaced within the next decade or two!

How can this source of useful information be made available (opened) to any system in the enterprise that needs this information?

Today, we see coming up hundreds of solutions to make this information available. Almost all of them are proprietary and do not support a seamless integration.

Until now, your priority was a high-speed network "copying" cyclically a small fraction of the available information to the network. Now, enterprise applications demand more information accessible at the system, and: reduced integration cost, more advanced technology, more productivity. To meet these objectives, you need be able to keep track, see, understand, analyze, and adjust to what happens on the plant floor. The enterprise needs to access information seamlessly between the process level and higher-level systems.

The standard ISO/IEC 9506 (Manufacturing Message Specification) dramatically improves device data integration in the enterprise information technology, reducing costs and increasing the agility of the whole life cycle of a technical process to react to changing business needs. MMS opens "Device Data Jail Houses":

Device_Data_JailHouse

Applying a small PC (e.g., a sub-credit card PC or any other integratable PC) to your system and running TCP/IP and an UCA/MMS server would provide this seamless integration - and it is standardized! You may apply any network technology that provides a TCP/IP link - and get started with a few mouse klicks. Serial links may be used, too.

All what has to be done is to locally connect the system's proprietary information to this - let's call it - "Proxy" PC. Since most of the installed systems do have serial interfaces the Proxy can be connected easily to the system.

Do not replace your whole equipment if it does not speak a standardized language. Just keep it and put an "interpreter" between you system and the seamless enterprise integration language: MMS and UCA.
