Testing PCo 2.1

That is the timestamp when the notification was created; could be different from when the value was changed.
Ideally they need to be the same. But you can expect a difference.

Hey Steve,
yes, I wanted to know the lowest possible interval for the update rate in PCo. If we defined the rate in the OPC server with 50ms I would like to set this value also in the PCo.

That's what we want to test: the performance and the stability of the PCo and the collaboration with MII .

  • OLEDB Fixed Query Comments Create Errors through PCo 2.1

    Testing PCo using OLEDB.  Everything is working fine except that existing Fixed queries with comments keep throwing syntax errors when executed through PCo. 
    Anyone else seen this, and if so what should we use to replace "--" for comment lines?
    The source system has no issues with these comment markers, and they worked fine in UDS 4.0.

    Fixed in SP06.

  • PCO Query: tag not found

    Hi,
    I am writing values to a datablock on a PLC using SAP PCO and OPC as middleware.
    It is working for all tags in the datablock except for 2.
    This is a screenshot of both tags in the OPC Quick client (I am using Kepware OPC server).
    I can read and write the tags from here.
    I have created a small test. In the MII workbench I created a PCO Query.
    Next I dragged the two tags from the tag browser on the left, to the right.
    For both tags I filled in a value.
    When I execute the query I get following error messages.
    M1 Order Dispatch/OrderQuantityTarget: Tag PoederMagazijn/ATS PLC/M1 Order Dispatch/OrderQuantityTarget not found.
    M1 Order Dispatch/OrderQuantityConfirmed: Tag PoederMagazijn/ATS PLC/M1 Order Dispatch/OrderQuantityConfirmed not found.
    Any other tags work fine.
    Thank you for your time.

    Hi Philippe,
    I tested a similar tag name in Kepware with the Simulator device as I do not have a Siemens hardware connection at present. I was able to read and write DWord tags without issues on these versions:
    Kepware V5.15.585.0
    MII 14.0 SP5 Patch 15
    PCo 2.305.2141.1051 (Patch 3)
    Additional question:  What is the Agent Instance Tag Query Cache Mode set for?

  • Problem with PCo 2.1 and ODBC data provider

    I am trying to connect MII 12.0 to an Aspen IP.21 data historian using PCo as the universal data server. Configuration steps so far:
    1) On the machine where PCo is installed, I have created an ODBC data source using Aspen's ODBC driver for SQL+.
    2) In the PCo management console I have configured a source system using the Microsoft OLEDB Provider for ODBC Drivers, and selected the ODBC connection that I created. I click "Test Connection" and get a successful result.
    3) In the PCo management console I have configured a destination system that points to an MII server. I put in the appropriate server/port/version/credentials, and click "Test Connection", and get a successful result.
    4)  In the PCo management console I have configured an agent instance connecting the source from step 2 and the destination from step 3.
    When I start the agent instance, I get the red box with a white X in it indicating that the connection was not successful. When I go to the error logs I see:
    Error     .     6     6076     RS1630IP21T01     Host     failed to create ConnectivityAgentProxy     General PCo Fault: The .Net Framework Data Provider for OLEDB (System.Data.OleDb) does not support the Microsoft OLE DB Provider for ODBC Drivers (MSDASQL). Use the .Net Framework Data Provider for ODBC (System.Data.Odbc)
    So, I installed the .NET data provider for ODBC to try to use that instead of the OLEDB provider for ODBC. However, when I try to reconfigure the source system, I do not see the .NET provider as one of my options. This is after a reboot, and starting/stopping all of the different PCo services.
    Any thoughts experts??

    Install PCo 2.2 on a server that has network access to your IP.21 server, and that your destination server (and SAP MII server in my case) has access to.
    In the PCo2.2 Management Console:
    In the "Source Systems" section:
    Create a source system of type "IP21 Agent"
    On the Server Settings tab, provide the server name of your IP.21 server
    In the "Agent Instances" section
    Create an agent instance, picking the source system you just created
    In the Query Ports tab, under port type, select the type of system you will be communicating to. In my case, this is SAP MII, but you may be using something different.
    Also under the query ports tab, you can enter enter a port number if you like. I just accept the default, which is 9000.
    If you are going to "pull" data from the IP.21 server, this is all you need. If you want to "push" data to a destination system from your PCo server, you will need to set it up under the Destination Systems section. In my case, I am doing a data pull, so I haven't done much with destination systems.
    Not sure what your destination system is, but in my case it is MII. For MII here are the basic steps:
    Create a new UDC data server in the MII menu under Data Services -> Data Servers.
    Set the IP address of the data server to the IP address of your PCo server.
    Set the port number of the data server to the port number you set up in the agent instance.
    Make sure the agent instance is started on your PCo server.
    Create a new business logic transaction containing a Tag query, and configure the tag query to use the new MII data server you just created to query the tag(s) you are interested in.

  • Notification Create time in PCO 2.1

    Hello,
    I am using PCo 2.1.6.0 and I have observed a difference of 4 hrs  between the Notification Create time and the time zone where actually PCo is installed.
    In my current scenario both PCo & the data source (OSI PI) are installed on the same server which follows the EDT/EST time zone.
    The notification message create date that is sent to MII (which also resides in the EST/EDT TZ) show a + 4 hrs (I think it shows GMT). I observe the same time when I do a "Test Notification Delivery" --> "View Sample" for a notification.
    On the PCo Mgmt Console if I navigate to Tools --> Options and further expand Global Properties and click Date/Time format the correct time is displayed.
    Additionally if I run a TAG query against the same Agent the correct time is returned.
    Why is there a difference for the notification then, when everything is in the same TZ? Am I missing some config setting in PCo?  
    I have not come across any SAP note on this issue and could not find any older posts referring to this behavior.
    Thanks for the help.

    Ud,
    Ok, so to fully answer your original question as to why there is a difference in the timestamps of a PCo notification and a MII Query to a PCo agent. 
    The notifications always use UTC which is universal time regardless of timezones or system settings and was agreed upon as the best approach to keep track of when messages were actually created.  If you want current timestamp of the server in the message payload you can add an Expression with the value of "datenow()" and I believe that this will give you the current timestamp of the PCo server.
    When you query a PCo agent from MII, the MII Time Engine will take care of the timezone conversion for you in order to ensure that date from the proper time ranges the user is asking for is returned to them.  Since the MII and PCo servers can be located in diffferent regions/timezones we have to handle this in our time engine.
    Does this make sense?

    Sam

  • MII 11.5 and PCo 2.1 and Tag Query Error

    Hi,
    I have KEPWare OPC server configured with a single tag, and with the OPC Client open.  I have PCo 2.1 configured with a single agent, and 'legacy' ticked with port 9001.  I have a UDS connector pointing to port 9001, and a tag query in 'currentwrite' mode, and can successfully write a value from the query editor (within MII 11.5) to KEPWare, when tested directly within the MII query editor.
    However, when I call the same tag query from within an MII transaction, and set 'TagName.1' and 'TagValue.1' to the values I want, I get the following error:
    "An item with the same key has already been added. at SAP.Manufacturing.Connectivity.Protocol.Custom.PCoQueryRequestHandler.ProcessRequest(Object handler)"
    I see this error in the PCo log.
    Interesting thing is, that within the transaction editor, when I select the underlying tag query, and the editor asks to generate the XML, and I say Yes, the underlying tag query runs fine (I can see the value getting updated within KEPWare).
    I've also tried with/without subscription items in PCo, plus different settings for 'Cache Mode' in PCo, plus using fully qualified tag name (ie: channel.device.tag as KEPWare sees it), etc, but in all cases I get the above error.
    Any ideas?

    Hi Diana,
    I upgraded to PCo V2.1.4.2, still same issue.  And yes, the data server (UDC) is checked as "Writable"!!
    As mentioned, the tag query runs fine in both "Current" mode and "CurrentWrite" mode.  Only when I call the same query from a transaction do I see this error.  Excerpt from Runner Log below;
    2011-02-23 15:20:32,390 [ServletExec: request: time=1298434832343, uri=/Lighthammer/Runner]

    If I leave the transaction Tag Query action (that calls the underlying tag query) without any assignment to TagValue.1, then there is no error, and the error as set in the aunderlying tag query is used.  But as soon as I assign values to TagValue.1 inside the transaction, I get the error.  I've tried passing a value via a local paramater etc, same issue.

  • Switching Kepware servers in PCO

    Hi Experts,
    We have Kepware on a different machine and PCO on another machine. To connect the Kepware server we installed 'OPCCoreComponentsRedistributable(x86)' on the machine where PCO is installed. we were able to create a source system using the details of the kepware server. For some testing we are trying to re-point the PCO to another Kepware server. For configuring the other Kepware server, we made the changes to the 'opc_remote' file to specify the details of the other kepware server. After making the changes to the file, we re-started the server on which PCO is installed. After re-starting when i am trying to create a source system using the details of the new kepware server, i get message 'No OPC servers found on the specified machine'.
    If i specify the other Kepware server that was provided earlier, i am still able to create the source system.
    I know that we can connect to only one Kepware server from PCO, but is it that we cannot switch from one Kepware server to another.
    We are on PCO 2.3 SP04 P7 and Kepware server is V4.190.341 - U.
    Regards,
    Darshan Sheth

    Darshan,
    For DCOM to work with PCo and Kepware, you have 2 options to configure the user access:
    1. Allow full DCOM access for domain users that are members of the server Administrators group, EVERYONE, SYSTEM and NETWORK, and allow PCo and Kepware services to run under LocalSystem account (some network admins will not allow this as it opens potential network security holes)
    2. Define named users or named Domain Group permissions for DCOM.
    2.1. Use the named user or users that are  members of the named Domain Group for the following:
        -  named user for Kepware server_runtime service
        -  named user for PCo Agent Instances
        -  administrative user to log into to PCo remote Desktop
    Avoid hosting PCo and remote OPC Servers on different Domains or on Workgroups -- should always be in the same Domain.
    I strongly recommend that you migrate to Kepware V5 and investigate using the Kepware OPC UA interface along with PCo OPC UA Agent where you are going to have remote OPC Server requirements, and avoid the DCOM issues altogether.
    Installing Kepware on PCo server, or PCo on the Kepware server will remove any DCOM configuration requirements.
    Regards, Steve

  • Write empty value through PCO

    Hi,
    I have a tag on my OPC server with datatype String.
    When I write an empty value to the tag through PCo I always get the error: "Invalid tag value for x".
    Writing a space works but this is not good because the PLC will interpret this differently.
    How can I write an empty value to a tag?
    I am using Kepware OPC and PCO 15.0.0.1959
    Thanks

    If i comment out.write(value) it prints fine to file. below it saves "test" at every columns.
    So that narrow it to this line "String value = (String)custTable.getValueAt(j, k);"
    for (int j = 0; j < rows; j++){
              for (int k = 0; k < columns; k++){
              String value = (String)custTable.getValueAt(j, k);
                   // out.write(value);
                    out.write("test");
                    out.newLine();
                    out.close();getValueAt dont return any data at all when it meet an empty column?

  • PCo 2.2 - ECC Connection Issue

    Hello,
    We have got PCo 2.2 version. I have to call a simple BAPI from PCo agent.
    I have created new destination system of type: RFC Destination (SAP NW).
    I have followed the steps mentioned in:
    http://help.sap.com/saphelp_pco22/helpdata/en/bf/3a68c28c1f4b8190d55b3e1e85a716/content.htm

    Please let me know if you have any clue on this.
    Thanks in advance.

    Hi Michael,
    I want to test the functionality of "RFC destination" in PCo 2.2 (and also to create an agent which use this destination for notification).
    Also, I have filled all the details on the 'Query Port' tab. But I am getting error as host 'xxx' unknown.

  • Pco monitoring issue.

    Hi Experts,
    I m trying to achieve Pco monitoring in SAP MII 14.0. I m refering following document:
    http://help.sap.com/saphelp_pco21/helpdata/en/f2/b1d0e885284db2baabef7eea15373e/content.htm
    I m able to do the Alert Configuration using active monitoring.
    But what condition should i check in MII transaction or which parameter from remote monitoring will tell me that PCo is down?
    I want to send e-mail once PCo is down.
    I have enabled the active monitoring and configured the MII system and got test connecttion as success.
    I am able to see the all projects in MII server . I configured the transaction and input variable (xml). After click on ok ,getting success message.
    After that I could not see any trx in transaction manager.
    I made dataserver connection to pco as error but still I could not see the configured trx in transation manager.
    Pls suggest me to overcome this issue.
    Configuration:

    Regards,
    Raj.

    Hi Raj,
    Question: But what condition should i check in MII transaction or which parameter from remote monitoring will tell me that PCo is down?
    Answer: The MII Transaction will called only when the PCo agent goes down or not able to connect to its source system. So you need not check anything in MII. The input param of the MII transaction will receive the error detection time-stamp and the node name (PCo instance or PCo and agent instance).
    Question: I made dataserver connection to pco as error but still I could not see the configured trx in transation manager
    Answer: Making the MII PCo data server go down or disabling it will not execute the alert or call the configured MII transaction. When the PCo agent is not able to connect to its source system then the configure MII transaction will be called.
    Hope that these clarifications will clear your doubts.

  • Error handling from PCO Query

    Hi,
    In my project I am integrating with a PLC through SAP PCO and OPC server.
    I am currently testing error handling if something fails on any of the involved systems.
    As a first test I stopped the agent instance that I use to read data from the PLC.
    When I try to write through the agent instance with a PCO Quaery I get no errors.
    The 'Success' attribute of the PCO Query is 1.
    The 'LastErrorMessage' attribute is empty.
    The only indication is the 'Output'which contains an error message.

    However, the same <Message> tags are used for success messages as well. So there is no clear way to identify an error.
    Is there any other way I can be sure the PCO query was able to write and catch any errors?
    FYI: we are using PCO 2.3 and MII 14.0
    Thanks!

    A small update. I tried again by upgrading the PCO version to 15.0 But still the same.
    I did the following 2 test cases:
    Unplug the UTP cable to the PLC and write data via PCO query
    Disable the agent instance and write data via PCO query
    In both cases the PCO Query returned the following output:
    Success: 1
    LastErrorMessage: <empty>
    The only information that I get is in the results but it is not a good practice to interpret this because I don't know all the possible messages.

  • MII 12.1 and PCo 2.1.5.1

    Hi guys,
    Hopefully this will be easy points for someone.  I am trying, for the first time, to connect our MII 12.1 to a newly install PCo 2.1.5.1.
    I also have a Phoenix Contact OPC DA server installed on the PCo server and (I think) I have PCo configured to see the Phoenix server.
    All I am trying to do now is configure MII to be able to do a TAG query through PCo.  I tried creating a UDC Data Server (no PCo option was available).  I used the PCo server's IP address and, at this point, I have tried a variety of ports (not sure how to tell which is correct).
    Can someone please point me in the right direction or point me toward some documentation that might be helpful?
    Note that we have successfully been using MII 11.5 talking to UDS and a Phoenix OPC server.  We are trying to get the same kind of thing working with MII 12.1 and PCo.
    Thank you!
    -Mike

    Using the same 11.5 UDC data server configuration in your 12.1 system should also work (12.1 tag query pointing to the already running UDS).
    Swapping the data server port and IP address (or just port if they are on the same server) should allow you to toggle your 12.1 application tests between the UDS serviing up the OPC data as compared to PCO.

  • SAP PCO Socket Connection VS HyperTerminal

    Hi All,
    We're trying to process an IP Barcode Scanner message using PCo notifications. How should I configure the subscription item / notification so that the received message is captured as using the HyperTerminal software?  Is there any documentation we should be aware of?
    Many Thanks,
    Paul Radulescu

    Hi Steve,
    We did our tests this morning. The source socket connection settings are below:
    I also attached a small log (FScan_Gi.txt) around one scan, where the alert is being raised, and the message is being sent to the destination system dummy transaction which only writes the file in the MII Web space (i.e. FS_msg_03.xml)
    My take on the multiple streams is that the scanner we used is a fixed industrial type one. The label being scanned contains multiple barcodes and the scanner scans all of them at once, delimiting the message with some CONTROL CHARACTERS, giving some headaches going forward.
    If I define an XML query and read the message saves "as is" by the dummy transaction above, I get a nice, but firm message :
    which comes from the control characters inserted by the scanner between the barcodes. PCo transmits the message as is, MII saves it as is, but when I try to open and process it .. I can't. Opening it in a transaction in workbench using the text-loader gives me a "prolog" error
    Funny. I feel like I get the best out of it sometimes
    Definitely I have to get rid of those control characters .. even by truncating the message. There are three barcodes being scanned, I presently need only the last one .. so my question is .. Can I use the expression editor and look for the message content after the "~" sign in the string over there (see FS_msg_03.xml) with something like stringpart('Fscan_GI', ~-location, length-of-the-string-after-~) I code below ?
    I have to wait again for the scanner to be available next Tue and test this without copy-pasting the content in the Value box above, but are you envisioning any possible "prolog" errors in the PCo log this time?
    Cheers,
    Paul.
