Wait time minimum

I would like to know which the smallest value than I can use  whith the  function wait time and wait time until ... . Is possible use values less then 1ms like microseconds. Because i have a problem in control with a board 6023E a step motor i need send two signals une    for control the direction and other for control the step but this pulses (step) need have  frquencys  larger than 10000Hz

I'd like to refer you to another thread I was in a while back.  The essentials are:
1. Use of a 'timed loop' (requires LV 7.1 I think) where the pulsetrain output is the timing source.  This allows iteration speed to be governed at resolutions below 1 msec. 
2. Timed loops get a very high execution priority, so you'll likely get better consistency than you would with 'Wait (msec)'.  Nevertheless, the timing still won't be guaranteed under Windows.
3. The example I posted doesn't sound like an exact match for your current app, but does illustrate a few ideas you may be able to use.
4. The example includes a 3rd counter used to count # pulses and verify correct behavior.  As mentioned, you'll need to get rid of everything related to that 3rd counter since your E-series board only has 2 counters.  Also, I wasn't able to test on an E-series board.  I think it should work there, but can't verify.

  • Routing - Minimum wait time - only workdays

    Hello,
    we need to block for an operation in the routing 4 days (external processing).
    We dont want to use any external processing data in the operation for purchase order creation, just block the time.
    I've used Minimum wait time as 4 days. The problem is Minimum wait time consider all days, and not only workdays.
    Can you please suggest how to maintain an operation / work center / material master  to allow me to block X-days only for workdays?
    Thanks,
    Evgenij

    I have overall 5 operation.
    - 4 operation, where I want to setup queue time, which CAN be reduced.
    -  1 operation with queue time which should be NOT reduced.
    For 4 operation I'm going to setup reduction strategy in OPJS and link to each operation, using Std Queue time. So in case of backwards scheduling the lead time can be reduced. Do I need to setup min. queue time in this situation?
    I hope you are aware of that if you want to reduce any operation system shortens the operation to min queue time if you do not want this to happen then maintain only standard queue time.
    For 1 operation, I'll not use any reduction strategy, just Std Queue time as you suggested. In this case it will remain for scheduling.
    Yes if you have maintained only queue time and no reduction strategy then system would considers queue time for lead time scheduling.

  • Wait time

    Hi, in our business after machining we need to keep the product in an area for 30 mins. after that the product will be moved to second operation. i think we can capture those 30 mins thru wait time. pls advise where and how to capture that 30 mins. pls note that we want to capture the cost of that 30 mins also. pls suggest.

    Dear,
    In work center queue time is your wait interoperation time or in CA01 or CA02 operation details screen minimum wait time has to be enter in the operation (view "Interoperation times")
    Then go to transaction CA02 ( change routing ) and schedule routing using following menu:
    Extras -> Scheduling -> Schedule
    In scheduling overview screen press on 'Scheduling results' button. Scheduled interoperation time calculated.
    Also note the wait time is scheduled according to the Gregorian calendar, i.e. neither a factory calendar nor the capacity of the work center are taken into account.
    Hope clear to you.

  • The wait time and resolve time is DEPLORABLE

    Today is the third day in a row I have called into Verizon for the same issue. Day one spent 25 minutes on hold and NEVER got to speak to a person before I hung up. Day 2 Had a 15 minute hold before I spoke with someone, who then told me I had to speak to directv about something that was related to the Verizon part of my service, called directv confirmed it was a Verizon thing with a supervisor. Called BACK into Verizon waited for 30 minutes before I spoke with someone, got 30 seconds worth of talk in before another 15 minute hold, he came back on no apology not anything about the absolute rudeness and lack of courtesy. He told me they would have it fixed by the end of the day. Now here it is the nest day still not resolved, So I write this (while on hold waiting to have the call answered, its been 20 minutes) She finally did answer and was down right rude and through me right back on hold. I am so fed up with big business...

    Agree.  I rarely wait more than a minute or two.  And except at really off hours don't hear a foreign accent.  NY area.

  • How to keep waiting time between processed messages !!

    Hi Folks,
    I have got one scenario required waiting time between processed messages. The problem as follows !!
    File --> Proxy scenario. I receive 15 messages from sender side (same messages structure) so working with one interfaces. File picking and transforming this message and split into 2 messages. messages are receiving to receiver. I am using BPM with 7,8 steps like receiving step, block , message transformation step , internal block 1 for sender 1, internal block 2 for sender 2.
    All things are working fine, messages are going to receiver properly. But customer requirement is , wait step required between processed messages before sender1. I have put wait step still, PI picks all messages in one shot processing and waiting for 2 minutes, after 2 minutes sending all messages at the same time, this process is not working.
    I have tried with wait step in mapping (Sarvesh) given excellent idea, still PI works the same way.
    Can someone please explain a bit why the messages or not waiting message by message. I am using EOIO with Queue name and file process mode "BY NAME" and I have tried "BY TIME" as well. I have given priority to this Queue. On BPM Queue assignment : One Queue.
    Please I am expecting positive answer !!
    Many Thanks in Advance
    San

    Hi Rudolf Yaskorski ,
    Not sure about your PI release and BPM model, do you create separate process instance for each file, or do you process files collecting them in one single instance? Are you using parallelization within your ccBPM ?
    I am using serialization, I don't think bpm can do Parallization until PI 7.0, but PI 7.11 has got has queue assignment. But I am using one queue. This must be serialization.
    To me it looks like your issue is not in ccBPM but rather more in polling files (as per your post file CC polls all 15 files in one shot). So if you wish to poll the files not at the same time some workaround is required. Possible options you could check out:
    A. Either implement "wait" in your mapping based on file name or other criteria (e.g. directory name). Check out if respective BPM instances are really created at different times.
    I have used wait step in mapping. These 15 messages has to go through one interface. So I am using one interface. But I have checked mapping process time in all messages on receiver system. Shows same timing, even though I put 40000 ms waiting time in mapping.
    B. Try polling different files (or use different directories) with different channels and coordinate starting / stopping of your channels by scheduling availability for each CC in RWB. E.g. you poll file 1 with CC 1. You start 2 minutes later CC 2 and poll file 2. And so on.
    I am not clear about this . On BPM waiting step is working and it keeps wait all messages, which are coming through one interface. Then it releases all messages at the same time.
    I don't know how to resolve this. I have tried with Transport acknowledgment, but all messages are going to reciver system waiting at receiver system in priority queue and processing in EOIO, but taking so long. Rather all messages go and sits in queue, I want to stop messages by message with 2 minutes time gap. How please?
    Kind Regards

  • Waiting time between entry posting in R/3 and avail. in BW

    Dear SAP community,
    We have set up a process chain which gives us the freedom to load GL account into BW on an ad-hoc basis.
    Unfortunately it is not really ad-hoc after we have  posted an entry in GL account in R/3 we need to wait approximately 1 hour before we run process chain in order to see posted entry. If we run process chain immediatly after posting entry we woul not see the entry in BW.
    Does anyone knows if there is a waiting time from when we post an entry into SAP R3 to when we can run the process chain and see the posting in BW?
    Thanks  a lot for you help.
    Stefanie

    Hi Stefanie,
    What is the Datasource being used?
    For old GL extractors, like 0FI_GL_4, there is a safety interval upper limit of 1 day, meaning data posted till yesterday will be extracted if the chains run today. There are workarouds given by SAP to extract most recent data for these.
    For new GL extractors like 0FI_GL_10, there is a safety interval lower limit of 1 hour, meaning the most current data would be extracted and there would be an overlap of 1 hour between delta loads and some records are extracted twice.

  • Wait Time / Timeout Time in waiting events

    Hi,
    From manual, I came to know that some of waiting events having wait time or time out duration. I have not understood, what happens if it has reached timeout. What happens next ?

( I have not understood what does mean "RENEW", Or what steps will be taken by Oracle, what happens if again reached timeout ) ?

  • How to increase the waiting time for response in Adapter Engine not in IE

    Hi Experts,
                It is a SOAP to Proxy Synchronous interface. SOAP system is sending the request to PI, PI sending the same request to ECC system, After execution of some logic response back to PI in 7 minutes. In ABAP Stack(sxmb_moni) processing the response message also successfully with success flag after completion of these 7 minutes. But exactly 5 minutes later getting the error at Java Stack RWB- in communication channel monitoring i.e
    com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.engine.interfaces.messaging.api.exception.MessageExpiredException: Message bd2bf8d0-b2c2-11e0-c383-001cc4fb5cb7(OUTBOUND) expired.  We have set the "runtime-HTTP_TIMEOUT" parameter as 3600. thats why in Integration engine it is processing successfully.
    kindly suggest me how to increase the waiting time for response in Adapter Engine. Exactly after 5 mins getting the above error in rwb, but in Integration Engine getting successful flag after 7 mins until then it is waiting for response with  status flag Log version.
    Thanks & Regards,

  • Wait step taking longer time than the defined wait time

    Hi,
    We have very simple BPM with 3 steps: Receive, Wait and Send.
    Wait step has following parameters:
    Type: Wait Specified Time Period
    Duration: 1
    Unit: Minutes
    From the above parameters idelly it should wait only for 60 sec and start the next step which is send step. But Wait step is taking following times: 1m 09s,1m 40s, 3m 40s, 1m 41s, 2m 10s, 2m 16s, 2m 46s, 1m 09s, 1m 40s, 3m 39s
    Does anyone know what could be the reason for above longer wait time??
    Thx
    N@v!n

    Hi Naveen,
    How did you measure these times? Tha additional time might be because of the message processing time included or size of the message is bigger to process.. or may be because of the network traffic..!!
    Check the each time stamp from message monitoring tool in RWB and verify for accuracy.

  • How to change wait time-- Urgent

    Hi,
    In monitor screen, under status, I am seeing the wait time date as next month date.
    So the technical status is yellow in color though the data is loaded.
    Where can I change this time.
    Thanks in advance

    Hi,
    When changed Timeout time in Info package it will reflect to particular infopackage only .
    If u changed in RSMO tcoe and settings- menutab
    Waiting time upto status incorrect - it will reflect to all infopackages.
    We can maintain  the value in years, months, days,hours,minutes and second also.

In the mean time the 24hrs watching time is ticking, not good at all. I know there are people that can watch instantly, any ideas or suggestions to solve this problem?
    thx

    Hi,
    After experiencing the same issue and trying different changes ie DNS settings, wireless position, channels etc the solution was the following:
    1) Switch off "Send Data to Apple". This is under Settings-General. Give it a few minutes.
    Hope this helps,

    My question is two fold... does anybody know where in OEM you can control the execution of this query? I would like to reduce the frequency it is run, or if that is not a good idea does anybody have any ideas from a tuning perspective?
    Ignite is reporting 1,440 executions, 621,776,455 buffer gets, and 2 hours of CPU wait time per day.
    Thanks in advance,

    A typical question for this forum.
    We use Oracle, we can't remember which version, and we can't be bothered to post it.
    We don't know Oracle, so we use a third party product (Ignite from Confio) to perform redundant monitoring on our databases, which is already being performed by Oracle Enterprise Manager, for free.
    Instead of trying to use the products which come with Oracle, we would like to wreck functionality, by tampering with things like frequency, and/or even adjusting Oracle provided queries, consequently invalidating our support contract for Oracle.
    And, no, we are not aware, provided the database is doing nothing, queries like this one will automatically surface in the list of top <n> queries.
    I would suggest you start to learn Oracle and dump Ignite. It is of no use to monitor your database with two tools, and OEM is fully integrated in Oracle.
