Originating Global Technical Committee: Automation Technology
Originating TC Chapter: Japan
Task Force (TF) in which work is to be carried out: Flow Oriented Manufacturing Line Operation System (FOMLOS)
Note: If a new task force is needed, also submit a task force organization form (TFOF)

1. Rationale:
a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)
The following changes are required, requested and agreed through the application studies and prototyping.

>Addition of ready check and abort function to Material Handshake.
>Optimize handshake scenarios.
>Change MD ownership change timing.
>Improve State and Transition table format.
>Simplify and improve document format and quality.
>Correct typos.


b. Estimate effect on industry.
4: Slight effect or effect not determinable
Sector or Company Information:

c. Estimate technical difficulty of the activity.
I: No Difficulty - Proven concepts and techniques exist or quick agreement is anticipated

___________________________________________________________________________
2. Scope:
a: Describe the technical areas to be covered or addressed by this Document development activity. For Subordinate Standards, list common concepts or criteria that the Subordinate Standard inherits from the Primary Standard, as well as differences from the Primary Standard:

Make following changes and corresponding changes. Note that some of the following changes are technically independent of one another, but they may not be broken up by document composition, so they may be incorporated into single line item revision.

>Improve Data Handshake with required modifications such as:
>>Shorten GD Valid duration for sequence simplification

>Improve Mode Resolution Handshake with required modifications such as:
>>Add capability to check readiness of Receive Port before assert Send request.
>>Add capability to Receive Port to decline send request
>>Add R_RDY signal for above purposes.
>>Replace X_MODE by simultaneous use of S_MODE and R_MODE for above revisions
>>Obsolete redundant states found through above revision works

>Improve Material Handoff Handshake with required modifications such as:
>>Limit ST0 to internal preparation and change starting condition by Starter Port
>>Add handoff Abort capability during Pause (Add ABORT signal)
>>Revise MD Ownership Change timing

>Add Related Information on SEMI A1 Services and Events for User Application

>Improve document readability and quality by making editorial changes and corrections such as:
>>Replace State and Transition tables with improved format
>>Reduce optional Setup Time and Hold Time from Logical Signal charts and move to one table
>>Add explanations, reduce duplicated explanations
>>Correct typos

b: Expected result of activity
Line-item revision to an existing Standard or Safety Guideline

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.

___________________________________________________________________________
6. Intellectual Property Considerations:
Note: Both a: and b: below should be checked for Revision of existing Standard(s) and Safety Guideline(s).

a. For a new Standard or Safety Guideline and for any part to be modified or added in a Revision of published Standards and Safety Guidelines:
the use of patented technology is NOT required.

If "patented technology is intended to be included in the proposed Standard(s) or Safety Guideline(s) " is selected above, then also check one:


b. For Revision, Reapproval, Reinstatement, or Withdrawal of existing Standard(s) and Safety Guideline(s):
there is no known material patented technology necessary to use or implement the Standard(s) and Safety Guideline(s)

c. The body of the Document and any Appendices, Complementary Files, Related Information sections, or Various Materials that may or may not be a part of the Document by reference:



NOTE FOR ‘the use of patented technology or the incorporation of Copyrighted Item(s) is NOT required’: If in the course of developing the Document, it is determined that the use of patented technology or Copyrighted Item(s) is necessary for the Document, the provisions of Regulations § 16 must be followed.

NOTE FOR ’will incorporate Copyrighted Item’: A copyright release letter must be obtained from the copyright owner prior to publication.
