Using comport data to start a sequence

All--
    I'm sure my terminology is bad here so allow me to explain what I want to do. I wish to monitor a com port and when the data stream arrives do things like parse, plot, send to indicators and write the data to a file. I have built a series of cases to do each of the tasks in sequence. I need a nice neat way to start the sequence when the data is finished arriving and then wait for the next data transmission. The data arrives about once per minute. Unfortunately, for now, the data will only come in at 1200 bps, so the transmission takes about 3 seconds. I think an event structure would work but I have no idea how to create/uses dataflow on the comport to start the sequence. Thanks in advance for the help.

I tried using the timeout on the "Configure Serial Port" vi but it did not work very well. The example uses a property node with the read function. How does this timeout differ from the Config Ser. port" timeout function?? Thanks.

 I'm not sure which example you are referring to here or which property node with the read function you are talking about.
How come you have 60,000 wired to the property node for data bits?  The only valid setting for that are 5-8.  And the only likely settings would be 8 or 7.  I think you have that setting confused with timeout.
I would recommend opening your serial port and configuring the settings only once during the intialization frame of your state machine.  Close the port only once in a frame that occurs once when you stop the program.  In between, you just carry the VISA reference through the loop by way of shift registers.
(Actually you should be using a lot more shift registers.  You are relying too heavily on local variables to get data from one state to another.  It could possibly cause problems down the road.)
 Your architecture right now is technically a state machine, but basically just a step above a flat sequence structure.  You can use decisions to determine which code to execute next.  See the attached screenshot.

  • Hi I  newly started using Iphone 6, I am not getting all the applications list under Use Cellular date for to restrict my unwanted apps on cellular data

    Hi I  newly started using Iphone 6, I am not getting all the applications list under Use Cellular date for to restrict my unwanted apps on cellular data
    Please help me out

    Hi Rajesh778484,
    Welcome to the Apple Support Communities!
    I understand that some of your applications are not appearing under Settings > Cellular on your iPhone so that you can restrict or allow use of cellular data. If you have some installed applications on your iPhone that are not showing here, the first troubleshooting step I would suggest would be to reset your iPhone. Please refer to the attached article for information on how to perform a reset.

  • How do you use the "Item Containing Start/End Date" in a Calendar?

    Hi
    I want to do a calendar where the days shown will be conditional to a certain interval. Now I though I could achieve that using the Item Containing Start Date of a calendar. But it doesn't seem to work. In the help it says :
    Enter an item in the application which holds the start date of the calendar. The format of the date in this item must be YYYYMMDD.
    This is what I did here
    http://apex.oracle.com/pls/otn/f?p=34530:1::::::
    I have 3 fields. 2 for the Start Date and End Date and 1 for the "Date Item" parameter. Only the latter has an effect on the calendar display, the calendar only displays the month of the "Date Item" (in monthly mode).
    Wether or not I check "Begin at Start of Interval", it doesn't affect the way those fields are affecting the Calendar.
    So, how do we use that "Item Containing Start/End Date" parameter?

  • If you're trying use your hotspot and connected to wifi on your iphone, does the wifi stop working and start using your data instead of staying connected to the wifi?

    Thanks for the quick response. What you have said makes sense but there is no rhyme or reason to he data used. I reset my cellular data counter to zero so both sent and received read zero. I was connected to wifi and let the phone to go into sleep mode. I waited about ten minutes and sent myself the same email four times, each with a 750 kb attachment. It was sent to my .me address so it was push mail on my phone. Sure enough I checked a minute later while bringing the phone out of sleep mode and checked the data. It showed just 10kb sent but 1mb received which just doesn't tally with the 4 x 750kb mails received. It just isn't making sense.
    He knows what you asked and has already answered it!
    I thought I had read where the iOS4 (or maybe just the iPhone 4) was supposed to be able to keep wifi connections alive while inactive. If the phone is sitting there on a charger with a wifi connection available, why use the 3G?

    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.

  • How to create a report using XML data source from Crystal Report Designer

    Hi,
    Iu2019m having Crystal Report Designer XI R2 SP4. Iu2019m trying to create a report using XML data source stored on disk. This is a customer order report and the xml is structured in such a way that it has an order details header part (master) and then it has several order lines (detail). One order line can have several order line characteristics (detail-detail). So what I need to know is now I can design this layout from the designer. If this was done using views I can do it with sub-reports but using xml data this seems to be different. Can you help me to design this layout? I have included the xml and xsd as well.
    Thank you in advance.

    Hi Sourashree,
    Thank you for the response and ideas you have given me so far. I can get the fetch the data from the data source without any problem. That is I do the following,
    1.     New Report
    2.     From Create New Connection-> XML
    3.     Provide the u201CLocal XML Fileu201D and have u201CSpecify Schema Fileu201D checked -> Next
    4.     Provide the u201CLocal Schema Fileu201D  -> Finish
    Then I can see the following under XML
    + CUSTOMER_ORDER_CONF_REP_REQUEST
            CUSTOMER_ORDER_CONF_REP_REQUEST
         CUSTOMER_ORDER_CONF_REP_REQUEST/CUSTOMER_ORDER_CONF_REP
         CUSTOMER_ORDER_CONF_REP_REQUEST/ CUSTOMER_ORDER_CONF_REP/ORDER_LINES
         CUSTOMER_ORDER_CONF_REP_REQUEST/ CUSTOMER_ORDER_CONF_REP/ORDER_LINES/ORDER_LINE
         CUSTOMER_ORDER_CONF_REP_REQUEST/ CUSTOMER_ORDER_CONF_REP/ORDER_LINES/ORDER_LINE/ORDER_LINE_CHARACTERSTICS
         CUSTOMER_ORDER_CONF_REP_REQUEST/ CUSTOMER_ORDER_CONF_REP/ORDER_LINES/ORDER_LINE/ORDER_LINE_CHARACTERSTICS/CHARACTERSTIC_ITEM
    And from here if I add the following three I can get all the fields I need to the report
         CUSTOMER_ORDER_CONF_REP_REQUEST/CUSTOMER_ORDER_CONF_REP
         CUSTOMER_ORDER_CONF_REP_REQUEST/ CUSTOMER_ORDER_CONF_REP/ORDER_LINES/ORDER_LINE
         CUSTOMER_ORDER_CONF_REP_REQUEST/ CUSTOMER_ORDER_CONF_REP/ORDER_LINES/ORDER_LINE/ORDER_LINE_CHARACTERSTICS/CHARACTERSTIC_ITEM
    Then I come to the Linking section. Here I canu2019t link anything. There is a common field called u201CInternal_IDu201D but I canu2019t link using it. So I get a message when I click Next. From here I add all the fields.
    For this point onwards only I need help. How do I group, add fields and design the layout so I can get an report output as follows.

  • Having problems with Verizon iPhone 5 using excessive data. Verizon will not help can anyone give me advice? Have family plan never went over 8gb of data in 6 years, now avg 14 a month and are not using anything different other than having iPhone 5.

    Switched to iPhone 5 on July 31st.  Since then our data usage has doubled.  Verizon will not help find out what the problem could be, they claim they are unaware of a problem.  I told them to look on the customer support page and many have complained about the problem.  Now on the apple site I see it may be an apple problem.  Some one needs to fix this.  Apple you want us to use your products, please do t make it cost us more money just to do what we did prior without problems.  Prior phones were iPhone 4 and we never had issues and never went over 8 gb's for 4 phones.  Now we are doing 14.  Can anyone tell me what is going on.  Getting ready to stop using cell phones all together.

    Well you could Restore it from your backup and see if that helps. If it doesn't Restore it as new and manually add things back until the problem starts again.
    I would also suggest trying a different SIM.
    Without iOS 7 there is no way to isolate what is using the data.

  • I cannot find all my installed apps on the "use cellular data for" tab on the settings menu.

    I have a new iphone 5s and on the first day I've received it, I updated to IOS 8.0.2.
    Today, I've decided to turn my cellular data on and, in order to consume less data, I thought I would disable some of the apps. However, only a few were available/visible on the "use cellular data for" tab. However, when, with the cellular data turned on, I opened a missing app on the phone, it would start to appear on the list (where it wasn't previously). Also, when I go to the app on the settings menu, it would not have shown the option, "use cellular data" before I've opened the app and now it does. Do I need to turn on every single app before I can select my cellular data preferences? I know people with the same phone and their apps appear all, as expected.
    I don't know if this is a problem of my own carrier but I don't think so, because the people I mentioned earlier have the same carrier.
    Any help would be appreciated.
    Thank you.

    Did you try to reset the phone by holding the sleep and home button for about 10sec, until the Appel logo comes back again? You will not lose data by resetting.
    If this does not work, did you try to switch off Cellular Data, restart the phone and switch it back on again?

  • How do I use the commands to start and restart the jmqbroker normally?

    How do I use the commands to start and restart the jmqbroker normally?
    Because I have tried to use "jmqcmd shutdown bkr" and then tried to type
    "jmqbroker" to start up. My screen hangs up and seems that the process
    hangs up. The message is
    [28/Jun/2002:18:29:07 GMT+08:00] [B1060]: Loading persistent data...
    [28/Jun/2002:18:29:08 GMT+08:00] [B1039]: Broker "jmqbroker" ready.
    The prompt is hanged until I press CTRL-C.
    Then I got the following message:
    [28/Jun/2002:18:32:07 GMT+08:00] [B1047]: Shutting down broker...
    [28/Jun/2002:18:32:07 GMT+08:00] [B1077]: Broadcast good-bye to all

    [28/Jun/2002:18:32:07 GMT+08:00] [B1048]: Shutdown of broker complete.
    Then, I use jmqadmin to invoke the console, I can start the broker
    again, it gives me
    Error encountered while connecting to the broker: "MyBroker":
    Broker Host: 'localhost'
    Primary Port: '7676'
    [C4003]: Error occurred on connection creation, - caught
    javax.jms.JMSException
    Please verify that there is a broker running on the specified host and
    port.
    I used ps -def | grep jmq there is no process anymore.
    Is it a bug? Would somebody have any idea on what went wrong?

    'jmqbroker' is the command to start a broker.
    When you type 'jmqbroker' in a command window,
    unless you put it in the background, the shell
    prompt won't return until the broker is shutdown.
    So when you see 'Broker "jmqbroker" ready.', it tells
    you that the broker is running and is ready.
    When you CTRL-C the process, it has the same effect
    as using jmqcmd to shutdown the broker. And so after that,
    there's no jmq processes running since you have just
    shutdown the broker.
    Remember that the jmqcmd/jmqadmin 'restart' command is to
    restart an already running broker. jmcmd/jmqadmin does
    not support starting a new broker instance.
    If you are using csh, end the jmqcmd command with an ampersand ("&")
    to have the broker running in the background. An alternative is to
    stop the process with Ctrl-Z then input the command "bg" to have that
    process resumed in the background.
    The problem with not being able to start a broker using the
    administration console is a documented limitation of the product that
    Yvonne also mentioned. Check the Administrator's Guide for that.

  • What is use of exclusion indicator in access sequence

    what is use of exclusion indicator in access sequence, if we tick this indicator what will happen to pricing procedure..

    Hi sahu
    If you are having more than one condition tables i.e accesss in your access sequence and if you put exclusion indicator in any of the starting tables then system wont search further as it stops searching.
    Ex : say you are having condition tables 501, 502,503
    and you have put exclusion indicator at 502 . then system will start searching from 501 then next it goes to 502 and it stops there and it wont search further.as you have put exclusion indicator at 502.
    But if you have put exclusion indicator to all accesss i.e., conditon tables then system will search from the 1st access and stops at the last access and if any valid condition record is not found in the last record then the system will take the previous conditon table record

  • How to know which transformation code is using the data target..

    Hi,
    Say I have a DSO ZXXX. Now there are transformations for other data targets, where the ABAP code is doing a select on this DSO ZXXX and reading and using that data for the result package.
    Typically if we wany to know if a DSO is used where where we try to do a 'display data flow' on that and find out. But that does not capture if that DSO is being read in the code.
    So is there any way I can find it ?
    Or do I have to manually go to each routines, start, end, mapping related routines etc and try to figure out ?
    thnks

  • How to define data-sources-alias.xml to use Oracle data source

    Hi,
    I created Oracle jdbc Data Source named "MYDS" in Visual Admin.  I added the alias = MYDS_ALIAS.  I set the Initial Connection to 2.  On the Monitor tab, I see a green line running across the screen.  The datasource MYDS is connected to the Oracle.
    Now, I would like to define "data-sources-alias.xml" to use MYDS.
    When creating data-source-aliases.xml it creates the alias by default on ${com.sap.datasource.default} which is the default DB.
    I followed the link --> How to point data-source-aliases.xml to another Datasource
    and my data-sources-alias.xml is now:
    <data-source-aliases>
         <aliases>
              <data-source-name>$</data-source-name>
              <alias>BRANCH50DS</alias>
         </aliases>
    </data-source-aliases>
    The "EAR generatation has finished successfully", but when "Deploy to J2EE Engine", I got the error below:

  • How to use Changed Data Capture?

    Hello,
    I want to use CDC to load my DW in real time. I am testing ODI in that mode.
    I have two tables:
    SRC Employe (empl_ID, name, surname, salaire, age) and TRG Employe( empl_ID, name, surname, CreDate, UpdDate) on SQL Server 2005. I wish to load data from SRC Employe to TRG Employe. I want that this data are charged in real time.
    how to do this? I know that I must use OdiWaitForData and OdiWaitForLogData but in ODI documentations, explanations are not sufficient.
    how to use OdiWaitForData and OdiWaitForLogData?
    thanks in advance

    Hello,
    but when I created a package and added OdiWaitForLogData, pb began. the step that has OdiWaitForLogData succeed. but my interface failed. the step "Load Data" failed.why?
    There is no reason for that. WaitForXXX does not affect the data stored in the CDC infrastructure, but just detects it.
    - What type of CDC are you using: simple or consistent set?
    - Did your interface used journal data only?
    - What error did you get precisely on the "Load Data" task?
    Could you tell me how to schedule a package?For scheduling, I think you should have a look at "Generating a Scenario" in the user manual. under the generated scenario node, you'll see the schedule node and you can start scheduling from here.
