  2. Dear Colleagues, Can anyone explain the difference between NOD and NWD as it defined in the DCS: NOD - (numeric;) Refracted object distance at near viewing point (meters). NWD - (numeric;) Working object distance at near viewing point (meters). We would like to use the one who fits most to describe the reading distance measured by the ECP. Thank you in advance for your support. Stay safe Haim S. - Shamir Optical Ind.
  3. No. The ddf file (can be opened with Notepad++ i.e.) only contains GoNoGo results. Note that the content of the ddf file can also be uploaded by TCP/IP. This upload string can contain additional labels such as JOB, OPC, MBASE, OPERID, TIME...
  4. According to the standard, Design deviation datasets are contained in files which have an extension “DDF” My question: can the DDF file contain additional labels aside the DDFMT dataset? For example, labels such that JOB, OPC, MBASE, OPERID, TIME...
  5. Hi Robert, Seems that my comment about TOL* vs TOLV* has not been adapted; could you double-check please? Tolerance records TOLADD, TOLCYL, TOLDIA,... on Table A.1a should be IMHO integer values (0;1;9) and not (min|max;). The min|max; are for TOLVADD, TOLVCYL, TOLVDIA,... There is also a typo for INSMOD, I see two times CCF as possible INSMOD; I think that for convex (anterior) surface, inifinity on axis it should be CXI instead of CCF
  6. Hi, Yaron, I apologize for being so tardy in replying. I'll go through your suggestions one-by-one. 1. I'm indifferent to the ordering of the revision history, but since it has been done newest first, it would take some work to revise it. Do you want to volunteer to do it, if the group approves of of doing it that way? 2. a) I also like "enumerated" better than "specified"; although it might be possible for only one literal value to be specified for a particular record's field value(s), in which case "enumerated" would be inappropriate. "Specified" is the more general of the two terms. However, we're splitting hairs here. "Enumerated" would be OK with me. b) We have always tried to enforce a measure of "terseness" in various text features. Just because a particular requirement can be relaxed when necessary doesn't mean that it's "effectively" a nullity. 3. Limited is there for a reason (namely, to limit the lengths of certain elements). My preference is to allow the constraint to be relaxed on an exception basis - if that's actually necessary. I don't recall why we added the "unless otherwise noted in the record definition." However, as I wrote earlier, I don't think that allowing an "override" eliminates its utility when it's not explicitly relaxed. 4. I'll ask Paul to fix the reference errors (he's still on board for that). 5. Same as (4), Paul will fix the revision history. 6. It was not my intention (or anyone else's, as far as I know) that this revision would change the location of an engraving. I agree that that is unacceptable.

  8. Unfortunately that is just the nature of things. Typically title pages and tables of content are not numbered so you will end up with discrepancies between the PDF page numbering and the document and TOC page numbers. As long as the TOC matches the page numbers on the document I hope people can find stuff. I don't really think that is something we can fix.
  9. @SJO - ENGLOC seems to have not been changed from previous versions, it's still type Literal rather than changed to Literal[;] as you suggested. Are you looking at the same document that has been posted here?
  10. Hi, A small 'flaw' in my point of view is that the indicated page numbers does not correspond with the pdf page numbers. For example, the page where "1" is written on (FOREWORD) is page 4 of the pdf document.This is sometimes confusing when refferering a page to a colleague or customer. Point 5.12 POWER MAP DATASETS: We recently added the labels M/O/H for the fourth field ( We may need to add them in DCS 3.13 Standard => @Thomas Zangerle? I'm glad to see that my remarks about ENGLOC and TOLx/TOLVx have been accepted 🙂
  11. A few comments, on draft ID 30. None I see as extremely critical, except for the last (which is therefore very much an objection rather than a comment/suggestion/question). I'm basing this on the Revision History list, assuming anything changed in 3.13 so far is listed there, I did not read through all the document: Regarding the Revision History itself - I think the revision order (newer on top) is the wrong choice here. This ordering makes sense for thing like blogs and web on-page-updates. But in a part of a closed document older to newer would make more sense to me. Literal data - The updated definition (in 3.3 and is a substantial improvement, and much clearer. That said: - 1 - There is some difference between the more general definition in 3.3.2 and the more specific one in . The one significant thing that was done in and I think would be an important addition to 3.3.2 as well, is that all possible values are to be enumerated in the record definition. Maybe change 3.3.2 from "...having permissible values specified in the standard" to something like "...having permissible values enumerated in the standard" ? - 2 - Since the standard is now clearer that all values are enumerated, is there a point in specifying maximum length? Especially when both specifies maximum length of 12 and allows the definition of each usage to go beyond 12? This is effectively no length limit when defining a Limited record field (since it is explicitly allowed to override 12), and there is no point in specifying maximum length as an issue for anyone using a Limited record field (if all values are enumerated then specifying length is meaningless, maximum length is always the length of the longest enumerated value). Maximum length in the definition of Limited should either be waived completely, or be specified in a way that doesn't allow a record definition to override it. (I'd prefer the former, but either option is better, and internally consistent, compared to the current effectively "there is a maximum length and it can be ignored by everyone") Reference Coordinate System for Backside Engraved Lenses - Previous issues with terminology and usage aside, just a quick note that has an internal reference error, I assume to the related Figure 2 below the section, stating "Error! Reference source not found." in the middle of the paragraph. Removed New DEFAULT label - The Revision History lists having added a new Label DEFAULT. Which is not actually added anyhwhere in the document. I see that it was there in an earlier draft, so I assume it was decided to drop the label, and it's just the Revision History which needs to be adjusted to match. ENGMARK coordinate system - Talked about it in the past, the changed definition of the ENGMARK coordinate system origin is highly problematic. From the previous revision I see that the definition changed from trying to define it on black center to trying to define it on block center, this is irrelevant for the practical objections and has the exact same problem. Again, there are plenty of labs who, for quite a lot of years now, rely on the fact that the coordinate source for engraving (using ENGMARK or ENGMASK records) is ER, not SB. (The Reference point for an Engraving operation being the Engraving Reference). Engraving is being decentered/offset from the Block center in plenty of labs by using SBBC__ + BCER__ records. Using the exact same set of job records, a change from 3.12 to 3.13 should absolutely not cause the engraving to move. It even more certainly should not cause the engraving to move to where the lab does not expect, or want, it to be. This definition expansion isn't clarifying things, it's changing things. And in a way that will have clear and significant and unwanted impacts on labs. I absolutely don't see any benefit whatsoever to doing it, just many downsides. Why change the origin of an already widely-in-use label?
  12. Hello, everyone. I hope you are safe and well. With any luck, you'll find a link on this message to a draft of the proposed version 3.13 of the Data Communications Standard. The first draft posted has a draft ID of 30; if any changes are made, and posted here, the draft ID will be incremented. Please download it, review it, and post any questions, comments, or objections on this forum, in this topic. I do not expect task force meetings to take place at the next Vision Expo West. We should try to discuss any issues that you may have with the draft on this forum; if it becomes necessary, we can arrange Zoom or GoToMeetings. I would like to be able to approve this version prior to our next meeting, which I expect to occur at Vision Expo East. DCS v3.13_DRAFT-030.pdf
  13. Hi All, I was informed today that due to financial challenges related to COVID-19 I'm no longer going to be employed by The Vision Council. Tomorrow 5/6/20 will be my last day. I wanted to say that it's been a pleasure working on these committees with everyone, not just during my time at TVC but even when I was at Signet Armorlite. Going forward please direct inquiries related to the DCS or LPDS Committees to Michael Vitale ( Regards, Paul

  15. Paul, this looks good. Section 5.2 will need to have the latest list pulled.
  16. Dear Colleagues, I hope all is well with everyone and their families during this worldwide crisis. I've spoken with the Steve's (Steve Nedomansky and Steve Shanbaum) and they'd like to try and make some progress with the draft review despite losing our face-to-face meeting at Vision Expo East. Attached you will find the most recent draft for the committee to review. Please post your feedback and comments in this thread so we can try and keep things organized. Please submit your feedback by April 30th, 2020. Thanks- Paul TVC Lens Product Description Standard 0.81-DRAFT.pdf
