  1. MUST HAVE SHOULD HAVE COULD HAVE Module # 160

  2. Advanced Bonus Topics Debug Data Capturing Feed History data Overlapping Feed Exercise

  3. Debug Data • Commands that Qi receives can be monitored externally • This data gives us more information on what is happening between the PLC and the Matroller. • Every Command that the Qi receives will be re-broadcast out the Ethernet port (1749) • Trace Debug O/P must be enabled in the Qi ! • Enabling “Trace Debug” • Via Web Pages goto >> Communications > Network > Ethernet • Check “Enable Trace Data” • Any S/W that supports a Winsock connection can be used to capture the data such as Hyper Terminal • (hyperterminal is supplied with Windows) • During commissioning this is an important tool that allows us to view what commands the PLC is sending. • Note: Once you are finished using this feature be sure to disable it. This feature adds an extra load on the CPU

  4. Capturing this Data • Run “HyperTerminal” • Select using: TCP/IP • Host Address: Your QiMPACT’s IP address • Port number: 1749 • Make sure that Connected is displayed on lower left • Test connection by viewing PAC Cross Reference Table • Data should appear on the HyperTerminal screen • Run a few more feeds • What do you see on your HyperTerminal screen? • Tip: Text should appear on your screen

  5. Analysis of the data • The Trace Debug O/P must be enabled in the Qi. • Typical Start Feed Command: • 4199114mp=13,ch=3,cm=1,sq=45,tg=1024.00,gp=0,ng=0,st=0 Qi0.3.1_0616 Clock in ¼ second intervals Channel Material Path Command number Target Qi firmware version # Ovlp feeds Sequence number Ovlp Grp number Command Status ARN06

  6. Data Capture – Feed History • Feed History data is also sent out of the Ethernet Port • This data is always transmitted • History data is always available, and is a string of text as follows: • (*hst* …”DATA IN HERE”….. *hst*) • This data is transmitted out of the Ethernet port and is available to any application to use • Qi365 has been designed to capture and present this data in a user friendly manner • The structure is described in two documents: • HistoryRecords.doc and TestDataHeadings.xls • The String can be copied and then pasted into the supplied spreadsheet and then parsed into the columns

  7. Overlapping Feed Exercise • These are our Material and their Parameters: • Primary Material MP1: • FlowAve: 50 g/s DrainTime: 5 s Feed Alone Time: 8 s • Feed Alone Tolerance: 6 s Target 1000 grams • Secondary Material MP2: • FlowAve: 25 g/s DrainTime: 3 s Target 300 grams • Exercise A • Draw a graph showing the feed time and starting points of these two materials

  8. Your calculations here – answer on next slide – no peeking !

  9. Exercise A Answer • MP1 feed time is 1000 ÷ 50 = 20 seconds • MP1 desired Feed Alone time is: 8 + 6 = 14 s • MP2 feed time is 300 ÷ 25 + DrainTime = 12 + 3 = 15 s • The overlap time is: 20s – 14s = 6s • The Primary will therefore be delayed by 15s – 6s = 9 seconds

  10. Graphical view Feed Time of 12 sec Drain Time of 3 sec Feed Alone Time of 14 sec MP2 - Sec MP1 - Prim Primary delayed by 9 sec Overlap of 6 sec 9s 12s 15s 29s

  11. Review Questions • Is there Debug data always transmitted out of the Ethernet port ? • What is the Port number for this data ?
