E-MAIL: Artistine Lethcoe-Reid, A.LETHCOE-REID@larc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO. 2 TO THE COMBINED SYNOPSIS/RFQ FOR 1-074-GJCI.2028. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to provide Questions & Answers for clarification to Solicitation GJCI.2028 and also to extend the response date to 9/22/99. Question -- A Tenney, Inc. or fully equivalent -- 60" x 144" Autoclave is listed. Is this a deliverable or just a device that we need to provide control interfaces to? Answer -- The Tenney Autoclave is an existing piece of equipment in which we are replacing the control system. Question -- Similarly for a Wabash or fully equivalent Vacuum Press; is this a separate deliverable or a device that we need to provide control interfaces to? Answer -- The Wabash Vacuum press is an existing piece of equipment which we are trying to provide a control for. Question -- What software is to be used to control the devices, i.e., Labview? Or is any software acceptable? Answer -- Communicating with an existing system, using software previously provided by Aerospace Service & Controls, Inc. Question -- It is specified on page 1 that the control system "shall include a snap i/o driven by M4rtu. Who is the manufacture of the M4rtu? Answer -- Commercial off-the-shelf item. Question -- Page 2 specifies that "the controller shall control temperature, pressure, load, vacuum, heat rate, cooling rate, all motors and related components. The only i/o that are defined for each of the 3 systems (autoclaves & vacuum press) are thermocouples, press transducers. What is the extent of the i/o to control the remaining items such as motors, load, and related equipment? Same for digital interlocks on vacuum press: How many? Answer -- The contractor must make the determination as to how many digital interlocks are required to complete the system. Question -- Is there a spreadsheet extensively defining all i/o the control system is responsible for? Answer -- No, contractor should define what is controlled. Question -- What is output of vacuum & press transducers? Is it standard 4 -- 20mA or something else? Answer -- Standard 4-20 mA or standard 1 -- 10 volts. Question -- What is the required delivery for the system? Answer -- 15 Weeks. Question -- Will an approach that offers an alternative t using OPTO Snap modules and the M4RTU be considered? Answer -- No. Question -- Has this system been purchased from others in the past? When and at what cost? Answer -- A similar system was purchase August 1998 from Aerospace Service & Control located in Sun Valley, California for $72,890. Question -- How many "nodes" are to be delivered in this project. The solicitation indicates the software must be capable of controlling 20 pieces of equipment, but it does say how many pieces of equipment we must supply hardware for. (We must supply a Nema-1 enclosure, dedicated I/O rack, I/O modules and 5 VDC power supply for each "node"). Answer -- Three pieces at this time. Question -- What is meant by "The system shall provide real-time arraneous modeling of the material properties and support control based on real-time or integrated future predictions of the viscosity, reaction rate, and other modeled variables". Answer -- Running off of models for dielectrics. Question -- The word arraneous and arraneuous are not in the English Dictionary. The word erroneous does not make sense in the sentence. Answer -- Arraneous is a term used in data for dielectric. Question -- Should we assume that the software is to be written in Opto 22's Factory Floor software package? Answer -- No, should be custom formatted. Question -- What is the method used to control the Tenney Autoclave and Wabash Vacuum Press? (i.e. relay closure, Analog Voltage or RS-232, etc.) Answer -- Voltage & RS-232. Question -- Are the above 2 items the only type of equipment to becontrolled? If not, what else? Answer -- An Autoclave from Thermal Equipment. Question -- The solicitation requests the system have the ability to control up to 20 different pieces of equipment. What are these 20 items and does the completed system require a fully populated SNAP rack for each item? Can you provide a list of required controls for each item of equipment? Answer -- Various presses and ovens that can be added in the future. Question -- The Solicitation requires arraneous modeling and references viscosity, reaction rate and "other modeled variables", what are the "other modeled variables"? Answer -- Crystallinity. The due date for receipt of offers is extended to 09/22/99. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on 08/26/99. Documents related to this procurement are available over the Internet and are in Microsoft Office Suite (Word 6.0, Excel 5.0, or PowerPoint 4.0) format and reside on the World Wide Web (WWW) server which may be accessed using a WWW browser application.
