How to set poll rate in IA OPC sever v5.1

Hi all,
I m very new to labview(using LV7.0), using IA OPC server version 5.1. I have connected 3 slaves on serial communication bus having slave ID 1,4 n 8. So, what should be the value of poll rate, receive timeout and receive gap ?? How they are related to each other?????
Waiting for ur valuable reply
Thanks & Regards,
Ratna

Hi,
In IA OPC server i have created 3 Modbus object for 3 devices, in each object pollrate is 0.6sec, receive timeout is 200msec n retry attemps is 0. Also the receive gap is 100bytes, with all these settings when i start communication i get Garbled communication from modbus secondary11) Bad CRC error and some times No communication response from modbus secondary. On serial communication bus all 3 slaves are connected as Slave ID1, Slave ID2, and SlaveID3, so how the driver will send query and receive response from all 3 devices?? Will it first send query to Slave ID1 then slave id2 and then slaveid 3 and will receive the response in a same manner or in a different manner????
Any suggestions will be valuable to me
Thanks n Regards,
Ratna

How to Set Polling Options of a DB adapter From EnterpriseManager/AdminCons

HI All,
We all know after Dragging a DB adapeter we can manually set the polling Options in J developer
However,
My query is how to Set Polling Options of a DB adapter From EnterpriseManager/AdminCons so that we dun hav to change our code and redeploy if any change is asked for.
My DB adapter is deployed to EM.(SOA Server).
Polling Options are like:
From the Polling Frequency list, select how frequently to poll for new records or events.
In the Database Rows per XML Document field, specify the number of rows per XML document when sending events to Oracle BPEL PM or Mediator. This is the batch setting between the database adapter and its consumer: Oracle BPEL PM or Mediator.
In the Database Rows per Transaction field, select Unlimited or enter a value to indicate the number of table rows to process during a single transaction.
When polling the database for events, you can order the returned rows by the selected column by using the Order By list. The best practice is to choose <No Ordering>, as message ordering regardless is not guaranteed without extra configuration.

Hi,
Inside your composite (in the EM), you can see there is a category table call 'Services and References'.
Under it, find the name of your JCA Adapter, where you've define the polling from the DB. Click on it and go to the property tab.
There you can find all the parameters you've set and more.
After you finish update it, click on Apply (this will automatically poll the data).

How to set polling interval for database adapter in interconnect?help plz!!

Hi
i have 4 database adapters with same name subscribing to same event in 4 different interconnect instances(i.e., same business event and application event in different hubs) and pointing to same source application database , same destination application database.
source application database have one oai bridge schema.When a message has to be sent,message will be enqueued in messageobjecttable.This message can be taken by 4 databse adapters.and send to 4hubs then 4 messages will be sent to destination application instead of single message.
To avoid this,I want to set database polling interval in 4 adapters sych a way that if one adapter take message in MESSAGEOBJECT TABLE,the other three adapters don't pick same message.
this way i can avoid redundacy at destination application.Please reply soon
Thanks

You would seem to have an extremely unusual use case for interconnect. The whole purpose of Interconnect is to concentrate the message processing into one hub and distribute the message to those applications interested in it. The use of 4 hubs from one application is probably not supported for precisely the reasons you are having trouble. Can you give us more details of your use case?
I am not sure that adjusting the polling interval for the different adapters will help. Since at some point you will get a collision where 2 or more adapters poll at the same time.

How to set Exch.rate-acct. field on Billing tab of billing document item

In R/3 4.7, we have billing documents with different values for Exch. Rate on each line item. We want the values to appear also in the Exch.rate-acct. field so the values will apply to the line items on the FI document. They are greyed out for us.
Does anyone know what to set to allow this field to be entered?

Lisa,
Not sure about 4.7, we used userexit_fill_vbrk_vbrp (rv60afzc) back on 4.5 to populate Exch.rate-acct field with the rate which was different from the rate used for invoice. I think you may put some logic into this userexit to populate the field based on your rules.

How to set scan rate with NI Switch scan voltages

Hi
I have SCXI 1130 switch and NI 4070 DMM . I have connected 3 voltage channels on the SCXI .
When I read just one channel at one time, I get correct voltage reading. here I gave scan input as ch0->com0.
Later , i placed a For loop in the block diagram and programmatically wired the scan channel input,
for the switch and read the voltage output from the DMM, i do not get the correct outputs.
That is , for my 3 channels, i gave For loop iteration count as 3 and ,'i ' is taken and appended for ch i ->com0. the DMM measurement is not proper. But if I highlight execution in the block diagram ( if i put the bulb and the probe), i can see the correct output voltages coming out. The moment, i turn off the execute high light, the program gives incorrect output. So do I have to give a scan dealy or what time has to be set to get correct values. I am using software trigger in the bloack diagram.

Hi Hema,
CJC is an acronym for Cold-Junction Compensation, and this value adjusts for the change in voltage caused by the thermocouple wire to copper wire junction.
For example, a J-type thermocouple will have thermocouple wire consisting of iron and constantan metals. When these iron and constantan metals meet the copper at the switch connection, a difference in voltage results. This difference in voltage is the "cold-junction". The difference in voltage resulting from the iron and constantan connection in the thermocouple is the "hot-junction". When you measure temperature using a thermocouple, what you desire is the "hot-junction" change in voltage. Unfortunately, the DMM is going to measure the sum of both the "cold" and "hot" junctions, and a CJC measurement is needed so we can adjust the measurement to remove the undesired offset.
Once Cold-Junction Compensation is performed, converting from voltage to temperature is fairly simple. Each thermocouple type has its own temperature to voltage conversion equation and associated coefficients. Here's a great resource for the equations, coefficients, and specific voltage to temperature tables:
NIST ITS-90 Thermocouple Database

How to set 'error' status with DB poll Adapter in OSB

1. Configured DB Adapter to poll rows with status 'notprocessed' and set the status to 'processed'
2. Configured FTP Adapter to write fetched rows from DB into a CSV file
Now my requirement is if any error like FTP server is not available, how to set the status in DB table to 'error'

Yes Vlad you are right, this will avoid another DB connection created in Error Handler.
I hope this will provide some lights on the usefulness of "Transaction"

How to change the USB polling rate on 1.6.8? OS X Snow Leopard

Hey Guys
i´ve got a problem with my USB-Gaming Mouse (Roccat Kova plus).
The mouse has got a 1000mhz polling rate with 1ms, response time and works up to 3200dpi.
The big problem with my MacBook pro is, that the USB side ports just response with a polling rate of 125mhz (8ms response time)
i know that 125mhz is more than enough for a mouse, but thats not the problem ive got. Everytime when i use the mouse with my MacBook the cursor is jumping arround, just a little bit. Its not a big thing, but its extremely annoying in games like Counter Strike where you need as much precision as possible.
There are many people out there who seem to have the same problem, so i look for a tool that can change the polling rate of the side USB to 1000mhz or can even change the mouse polling rate to 125mhz.
I know that there are some developer tools who can do this, but i hope the community can help me with that.
yours Christian

sometimes you dont see the easyest way to fix it
i always looked for a driver for mac, but there was nothing.
After your reply i installed the original driver software on my old Windows System and i found out that i can change the polling rate under "advanced options".. well, i feel like an idiot now, but its all fixed. I could even change the graphic details from low to very high! Just because there are no more mouse lags! ;D
thx for your fast reply

How to set screen refresh rate for linux console (runlevel 3)?

Hi,
I have a CRT monitor, so the refresh rate is always needed to configure. I use 720x400 resolution in console, but the refresh rate is 70hz. Are there any ways to get it higher in console (with KMS or without)?
Last edited by AleXoundOS (2009-11-04 12:27:09)

thank you for replies
But setting the resolution, e.g. vga=773, would not change the refresh rate, or would it?
It would, but usually not to the maximum provided by the monitor. May be it is real to find the place, where it looks for available resolutions linked with refresh rates...
According to the Gentoo page I can use uvesafb for setting refresh rate as well as other settings. And then I found uvesafb page in ArchWiki. But the way to set proper refresh rate is not so easy as I expected, because I need to install uvesafb and it needs additional daemon. And also I think KMS can't work here. However it's better than nothing, if I don't find any other way, I will try this one.

USB polling rate 1000hz does not work (only 500hz)

I have 3 mouses, a Zowie FK2 mouse, a Steelseries Sensei Raw and a Razer DeathAdder 3.5G mouse. All of them fully support 1000hz USB polling rate (it's one of their main selling points) and I have already tried them successfully (1000hz) on Windows 7.
Following the Arch Wiki guide, I successfully enabled 1000hz mode with usbhid module.
$ cat /sys/module/usbhid/parameters/mousepoll
1
$ systool -avm usbhid
Module = "usbhid"
Attributes:
coresize = "48595"
initsize = "0"
initstate = "live"
refcnt = "0"
taint = ""
uevent = <store method only>
Parameters:
ignoreled = "0"
mousepoll = "1"
quirks = "(null),(null),(null),(null)"
Sections:
.bss = "0xffffffffa005e960"
.data = "0xffffffffa005e000"
.exit.text = "0xffffffffa005b169"
.gnu.linkonce.this_module= "0xffffffffa005e700"
.init.text = "0xffffffffa0044000"
.note.gnu.build-id = "0xffffffffa005c000"
.rodata = "0xffffffffa005c080"
.rodata.str1.1 = "0xffffffffa005c8c4"
.rodata.str1.8 = "0xffffffffa005cd18"
.smp_locks = "0xffffffffa005c7d8"
.strtab = "0xffffffffa0046f80"
.symtab = "0xffffffffa0045000"
.text = "0xffffffffa0054000"
__kcrctab_gpl = "0xffffffffa005c050"
__ksymtab_gpl = "0xffffffffa005c030"
__ksymtab_strings = "0xffffffffa005da40"
__mcount_loc = "0xffffffffa005d7b0"
__param = "0xffffffffa005d750"
__verbose = "0xffffffffa005e200"
So according to the above outputs usbhid is already running with 1000hz (1ms polling rate).
But when using evhz which measures the HZ both with the DeathAdder and the Zowie FK2 I get this:
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
When I use the Steelseries Sensei Raw setting 1000hz using the sensei-raw-ctl, evhz reports 1000hz successfully.
So what is going on? Why the two other mouses are stuck on 500hz and can't get to 1000hz?
I now only use Zowie FK2 which is much better than the other two mouses and I need 1000hz because 500hz has microstuttering which impedes my gaming use.
Is this a bug? How can I fix this?
Last edited by Nektarios (2015-02-17 04:01:26)

In the end I found out that this maybe is just a reporting bug with evhz utility, the mouse runs in 1000hz correctly. I tried dimr.exe with WINE and it reports 1000hz correctly.
Though I find it funny that when I tried mousepoll=2 (500hz) and mousepoll=4 (125hz), dmr.exe still reported ~1000hz. Now I'm not really sure if it is a reporting problem with evhz, or with dimr.exe.

How to set up a FTP and web server and integrate with DMM 5.2

Hi All ...
I need to set up a external server only for content publishing to reduce the overhead of the DMM server .
can anyone guide me on how to set up the external server and intergrate it with the DMM 5.2
Thanks

semuthu,
Notes from the Release Notes:
Compatibility Limitations with Microsoft Internet Information Server (IIS)
DMPs that use firmware release 5.2 are compatible with only one version of Microsoft Internet Information Server.
That supported version is IIS 6.0 for Windows 2003 Enterprise. If you do not have the supported IIS version but
want your DMPs to retrieve assets from a webserver, we recommend that you use Apache instead of IIS.
I would suggest using Apache instead of IIS for the webserver service. IIS can be used as FTP if needed.
There are plenty of Documents on the Web about setting up Apache and FTP for servers.
Using Apache with Microsoft Windows

Quick HOWTO : Ch20 : The Apache Web Server
http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch20_:_The_Apache_Web_Server
Once the Webserver is setup and operational. You simply store your media content on the Webserver
and then have your DMS assets in the media library use an external URL address for its location.
If you want to use external server for other features in the DMM, you can can see how to configure

Reg: How to Stop Polling of JDBC Adapter without Scheduling the adapter

Dear Gurus,
Here I am having one requirement. My clients wants to send data from JDBC adapter (ORcale System table) to R3 system via RFC.
His Requirement::
1. He is not telling the time of data flow from Oracle server so that based on that we can schedule the adapter in the Communication Channel monitoring (Availablitiy Time Planning) or Else we can Schedule by deciding the setting of the polling interval time.
2. He is telling that When ever he waants to send the data he will place one dummy file in the File Adapter FTP location so that it will became an Indication for u to poll the jdbc adapter and to transfer the data to R3.
3. Untill he keeps the file or gives indication he doesn;t want to communicate with Oracle server due to some security and it s a most important data base he doesn't want to disturb that Oracle Server as so many business are running on that.....
We Proposed::
1. Atleast you need to tell the scheduling time or poll interval time so that we can schedule our adapter.
but he s not accepting for this
2. Atleast U need to give access for Data base to enter one more extra field like STATUS CODE so that we will add one number and we keep on Update in the Update table and based on that Update table statement it will poll.
but he s not even accepting for this
3. Finally we prposed that to create another table in the Oracle SYstem as Dulplicate Table which is similar to Standard Orginal table when ever he wants to pick the data please keep that data in this Duplicate TABle so that JDBC adapter will pick the data from thsi TABLE instead of picking the data from that standard table so that it will not effect any standard table data in the table.
but he s not even accepting for this
We have done some R & D:::
1. WE approached even through BPM and via switch conditions is one scenario
   FILE RECEIVE >SWITCH CONDITION> RECEIVE AND SEND or else EXIT
2. Using correlation in anotehr scenario means correlating File adapter and JDBC and based on one dynamica value it will goes to SEND STEP ( RECE IVE --> RECEIVE --> SEND STEPS )
Even though we know this...concept that...we jsut tried::
In BPM we can control the flow in XI 3.0 but we cannot Stop the Polling of JDBC adapter at backend because one the data comes from FILE adapter it will keep on HOLD untill it receives the JDBC from Oracle then based on the condition or Correlation it will goes futher SEND step means after that file adapter is picking file or not ...what ever it may be JDBC will polls at backend and brings that data to BPM"
Hence sugest me How to Stop Polling of JDBC Adapter without Scheduling the adapter or else using STATUS CODE Update statements in JDBC Tables
Regards:
Amar Srinivas Eli

Hi! All,
Finally I decided to do the scenario in two steps:
1: FILE REQ --> JDBC REQ -->JDBC RES --> FILE RECV
2: FILE RECV --> RFC
But I am getting issue while doing first scenario
Desgn :
I have created 2 Synchronous interfaces :
1) FILE 2 JDBC REQ
In this a) out put message is FILE Req
          b) Input msage:; FILE RES
2} JDBC2FILE RECV
        a) Output mesage;; JDBC REQ
        b) Input Msge :: JDBC Response
Mappings:
1) File REQ-->JDBC REQ
2) JDBC RES-->FILE RES
Interface mappings:
1: FILE 2 JDBC REQ--> JDBC 2 FLE RECV
CONFIGURATION ::
1: One Seder File CC
2: Two reciever CC's one is for JDBC RECEIVER and other s FILE RECEIVER
3; One Sender Agreement
4: 2 Recver agreements
5: One Interface Determination and
6: One RECCV Determination
My Question;;
1. First let confirm whether my development steps are right or not ?
2: Another thing s I am not sure reg Configuration Steps means
whetehr one interface determination and one Receiver Determinations are required or not as these are synchronous Interfaces
3: main Issue is::::
If my scenario s FILE2RFC2FILE then I will get RFC response automatically but here issue is this is JDBC
My reqquirement is By sending one Field from fILE to JDBC REQ it needs to send entire TAbLE records as a Response to file as XML
without having Sender JDBC how can I send the JDBC Res to FILE and If that is the case then again JDBC adapter is polling which is contradict to the client requuirement which i explained above.
pleas suggest me the Detailed steps mainly Colloboration agreements and logical routings and
also explain in detail if i can go for BPM
Also give cleear blogs but before giving make sure that it contains detailed screen shots because aIready gone thorugh
Scenario File-JDBC-RFC
File<-->JDBC Sync coomunication.
