LOUISVILLE, KENTUCKY <br /> August 3, 2010 <br /> Tuesday, 5:44 PM <div>&nbsp;</div> Dear Mr. Krishna: <div>&nbsp;</div> I knew very little about what SCADA actually meant or what it's initials stood for. <br /> Using Yahoo's browser search engine to do a search on SCADA, I found a brief description and illustration of a SCADA industrial system from www.wikipedia.org. <div>&nbsp;</div> While reading a story about SCADA systems at the Industrial Society of Automation's website, www.isa.org, I found an excellent source of information under Technical Information called "InTech". I was curious if anyone at IBM was aware of this website. If anyone there at IBM could view this information, it could provide innovation in poorly needed industrial regions of the United States. <div>&nbsp;</div> Signed, <div>&nbsp;</div> setun_5@yahoo.com

I don't know about isa.org .... But look at these links: <br /> http://mqtt.org/ <br /> and <br /> http://www-01.ibm.com/common/ssi/cgi-bin/ssialias?subtype=ca&amp;infotype=an&amp;appname=iSource&amp;supplier=877&amp;letternum=ENUSZP10-0255 <div>&nbsp;</div> The FAQ in MQTT.org says: <div>&nbsp;</div> How does MQTT relate to SCADA protocol and MQIsdp? <br /> The “SCADA protocol” and the “MQ Integrator SCADA Device Protocol” are both old names for what is now known as the MQ Telemetry Transport (MQTT). The protocol has also been known as “WebSphere MQTT” (WMQTT), though that name is no longer used. <div>&nbsp;</div> <div>&nbsp;</div> also to add typical legacy SCADA protocols include Modbus RTU, RP-570, Profibus and Conitel.
