PCo 2.1

Hi,
We are looking at upgrading to PCo 2.1. Can somebody comment about its capabilities in detail? Its my understanding its going to have UDS capabilities as well besides the inherent listening capabilities. If you could share some documentation, that would be great too.
Regards,
Chanti.

Hi Chanti,
Here are few features of PCo 2.1,
1) Agent Toolkit (VisualStudio .NET)
2) Custom agent development
3) Provides Execution Services (i.e. Query) in addition to the existing notification capabilities
4) New query capability available with MII V12.2
5) Also supports legacy query and command capability (UDC queries) for MII 11.5, 12.0, 12.1
6) Remote PCo configuration from the MII system without logging into the computer hosting the PCo instance
Also supports some new agents other than OPC DA and OPC A&E,
1)OPC HDA Agent
2) OPC UA Agent
3) OLE-DB Agent
4) OSISoft PI
Hope this helps!!

Error in creating PCO Connector in SAP MII 14.0

Hello,
We have successfully installed SAP PCo 2.3 in one of the servers. This PCo Server is independent of the server on which MII Application is installed. So DCOM had to be done and it was achieved successfully.
On PCo Server, in management console, we were successfully able to add Source System - PHD as shown below:
After that I created an instance of Source system and kept it running.
Now when I am trying to create a PCo Connector in MII 14.0, I am getting following error:
So I have few questions about it:
1) Am I missing any configuration step?
2) Is it mandatory to setup Destination System in Management Console as MII. I am getting an error while configuring MII system as destination system. Error is as follow:
3) Is it any per-requisite to Create a PCo Connector in MII?
4) Is there anyway I can browse the tags from Management Console only without using MII just to check connection to PHD?
Any help in this matter will be really helpful and will be appreciated.
Thanks,

Hi Rohit,
I checked and found that PCo Mgmt service was not started. SO I started it and now I am able to get the XML when I open PCO Mgmt URL in the browser of PCo Server
But,
When my agent is running, I don't get Browse button enabled in "Subscription Items" tab.
When I stop the agent instance, I can see Browse button enabled in "Subscription Items" tab. But when I click on browse, it gives me following error:
Not sure what's wrong?

How to read the tag values sent by PCo to MII transaction

Hi everybody,
I have an Agent created inside PCo and its listening to a data server. I have also created a notification object which triggers my MII Transaction (after certain condition is getting fulfilled).
Now, I want to pass certain values from PCo to MII using the notification object. For this I have tried 2 options:
1. I defined one input parameter in transaction of type 'XML'. But this did not work. When I used 'Tracer' to check the received values, it showed empty.
2. Since XML variable did not work, I tried with 'String' variable. It worked but the entire input data was in 'String' format.
Actually I used XML_Saver to save the string and given filename as '.xml'. When I opened that xml file, it was looking like this:
<<unable to write XML here>>
Considering the above 2nd option, how can I extract the particular 'Tag' values from XML string. Since the string is not in the format of 'Rowset/Row/Row', I cannot specifically assign/map those tag values to any other variable inside MII transaction.
===========

Hi, I was trying to post the xml string. It was not possible yesterday (because, SDN editor has converted xml part into some irregular string).
Now, I am trying to post the string by removing the special characters. Please try to understand it.
Now, my question is how to retrieve the CDATA value 5599999999 using xpath. Please help.
NotificationMessage
Body
Values
Expression1 type xsd string
CDATA 5599999999

Using Labview to save image from PCO camera(12 bit images)

Hello,
I have labview 8.5 version in my Winxp. I have PCO camera (pixelfly). So far I know that it saves 12 bit images. I used normal save pattern of labviewas png,tiff or jpeg. As .pngit saves the images as 32 bit and as bmp it takes 8 bit images. But the picture quality is not good. I used IMAQ to take single picture and to save it I used IMAQ Write File 2. I used the following mechanism.
1) IMAQ ImageTo Array--> To unsigned word integer--->IMAQ ArrayToImage--->IMAQ Write File 2---> save it as .png file.
Please inform where I made the problem. Why the picture is not as like as 12 bit images of PCO Camera.
Thanks,
Stuttgart University,Germany.

IMAQ Create.vi supports Grayscale(I16) and RGB (U64). Both should be suitable for 12Bit Greyscale.
Documentation of "IMAG Write File 2.vi" says:
IMAQ Write TIFF File 2
Writes an image to a file in TIFF format.
Note 16-bit monochrome images and 64-bit RGB images are nonstandard extensions of the TIFF standard. Most third-party applications cannot read 16-bit monochrome or 64-bit RGB TIFF files. For compatibility with most applications, write 16-bit monochrome images or 64-bit RGB images into PNG files.

Issue in PCo 2.1

Hello Experts,
We are facing an issue with SAP PCo while working in SAP MII 12.2.We are not able to start a particular agent instance.First we are stopping the agent instance and then when we are trying to start the same it is taking a huge time and finally showing the following error.
"Error 1053: The service did not respond to the start or control request in a timely fashion."
The PCo version is 2.1
Kindly advise.
Regards,
Shawna

Hi Shawna,
Please provide more information on your system.
What patch or SP is PCo on?
What version, SP, and build/patch are your MII and NW installations?
What are you connecting PCo to (what historian or OPC data source)?
Where is PCo installed relative to NW/MII and relative to the data source (firewalls?)?

How to pass tag name and value dynamically in the output of PCo notification?

Hi,
I have a requirement to develop such a scenario where there can be multiple no of tags in PCo (Say 10) but there will be single notification to push the tag name when the value got changed and the changed value to MII. for any value change for any of the tag, the notification will be trigger. So As per my knowledge I have to pass the tag name and value dynamically in the "output" tab of the notification. But need your support to find out how to pass them dynamically.
Thanks in advance.
Regards,
Suman

Hi Suman/Jeedesh,
As per Pco notification, it will trigger whenever any of the tag value changes in Agent instance subscription items.
For above issue, My suggestion
1. Create DB table name TAGLIST with 200 tags as rows in columns (Tagname, TagValue)
2. Based on notification trigger, create a transaction and update values w.r.t TagNames in above table
3. Next time, when notification trigger with fresh value for any of the tag, cross check with existing TagName with Value and update in DB table.
4. And in the mean time, send those Tag details vie mail trigger or as per requirement
Instead of creating 200 notification, above is a just alternate way suggestion to achieve dynamic tag value change notification.
Hope it might solve your problem

Transporting PCo Setting Through Landscape

Hello,
We are using PCo 2.1 and MII 12.1. We have 3 instances of each for development, staging, and production.
In order to transport changes from one environment to another, I am using PCo's Export/Import capability. This works ok except that, after importing, I have to manually edit the Destination System's Server Name setting to change it to point to my staging MII host instead of my development MII host. I have the same issue going from staging to production.
I would like to avoid the manual editing. Is there a way around this?
Thanks,
Mike

Mike,
I belive you could just import the Agent by iteself. Instead of importing the source and destination everytime.

Ajay.

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?

PCO 2.2 - OPC and IP21

Hi,
We are looking at connecting to IP21 via PCO OPC DA connector.
Can PCo only poll the IP21 OPC server for eventing or can one set up the IP21 OPC server to advise PCO on data changes for
eventing purposes ?
Also what is required on the server where PCo is installed to enable OPC connectivity, for browsing the IP21 we have established that you need the following dlls in the PCo system directory :
cimsrvapi.dll
CimWin32Util.dll
infoplus21_api.dll
ip21admin_client.dll
ip21ezrpcw32.dll
ip21winrpc32.dll
libc21.dll
PCo is running on Windows server 2008 R2 and the IP21 is not on the same box.
thanks

Hi ,
I got it working to be able to get the notification working. Although one still cannot browse the IP21 tags, and all tags are still shown as a name space.
a. I installed the Matricon IP21 OPC server on the same box as IP21 Historian.
b. I connected to the IP21 server and configured new aliases in the Matricon IP21 OPC server to look at the IP21 tags
c. I then configured PCo OPC DA agent to look at the Matricon IP21 OPC server and got the subscriptions to work, and PCo can browse the MAtricon IP21 OPC server tags that I configured , so the browsing seems to work via this OPC server
d. Then I tried to fire up the OPC DA agent in PCo that I previously configured to look at the Aspentech IP21 OPC server, and the configuration now started to work (still can't browse the tags)
e. I uninstalled the Matricon IP21 OPC server and the configuration in step d. still worked.
So the conclusion is that the Matricon IP21 OPC server did some sort of a configuration that made the orginal configuration functional, this however now leaves me the question of what did this driver do to get things working.
Now I sit with a new challenge I have PCo installed on a seperate server and in a different domain as the IP21 OPC server.
What I have so far
1. The Same local user on both the PCo box and the IP21 OPC server with Admin rights
2. I can see the IP21 OPC server from the PCo box and access it
But the issue is as soon as I fire up the Agent to run it fails to start with the following error:

Response time too slow when there is competition in the same connector PCo

Dear all, I'm having a problem with using PCo 2.1.
I created all the conections in PCo with OSIsoft PI and when I create a TagQuery
on MII to get the values of a tag is not occur problem in response time.
But when I have another TagQuery or Transaction, which is collecting data at the same
time, sharing the same connector, the time response is very slow.
Using the UDS this problem does not happen.
So problem is that when there is competition in the same connector, the response time is extremely slow.
Has anyone experienced this?
Regards!

Hi Udayan,
Thanks again for attention,
I found this problem on the two MII versions, 12.0 and 12.1.
The UDS and PCo are on different servers and using different ports too.
I didn't find errors on netweaver about this, but I'll verify one more time.
On true, on version 12.0 of MII there is two connections with PI, one PCo and another UDS, that are using the same port. But this does not happen on the MII version 12.1, there I'm using different ports.
Thank you very much!

Pro*Cobol PCO Compilation problem in Linux

Hi,
DB :oracle 11g on RHEL 5.5
when we are compiling the (Pro*cobol ) PCO code it is giving us the error :
System default option values taken from: /oracle/oracle11g/app/product/11.2.0/dbhome_1/precomp/admin/pcbcfg.cfg
Error at line 320, column 35 in file BR2385.PCO
WHERE A.SOC_NO = :PARAM-SOC
..................................1
PCB-S-00223, Undeclared variable "PARAM-SOC".
when we change the pcbcfg.cfg file with flag : declare_section=no it's compile without error.
But in this scenario cobol app doesn't run.
if we declare the undeclared variable in the section
EXEC SQL BEGIN DECLARE SECTION END-EXEC.
PARAM-SOC PIC X(25).
EXEC SQL END DECLARE SECTION END-EXEC.
and compile it with declare_section=yes then cobol app. run fine.
Are different files generated (cob,int,gnt) after compilation with the option declare_section=no and declare_section=yes.
Pls help us in this regards. we have lot of file which having these issue and we don't want to do manual changes "EXEC SQL BEGIN" in it.
Thanks in advance..

Your code is faulty and has to be fixed.
No compilation problem is present, the compiler correctly barfs.
As this is not a support forum, kindly keep your non-issues out of this forum.

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.

PCo 2.1 and Proficy iFix using OPC DA

I'm finding some interesting behavior when trying to access Proficy iFIX HMI / SCADA with PCo 2.1 using OPC DA.
PCo Version 2.1.0.55
iFIX version 5.1
SCADA OS: Windows XP Pro, SP3
MII Version 12.1.5 Build(99)
What happens is that when I do a tag list in a tag query, instead of getting the tags, I get the propertes of the tags in the tag list, so what I think PCo's OPC client is doing is resolving to the lowest level of the tag list, which of course would be a tags individual properties. iFIX UDS does not exhibit this behavior.
I've tried a variey of settings in PCo, including "Force Flat Namespace" to no avail. Is there an option to set how far down the tag list drills?
Here is my setup, I know most of these settings have nothing to do with my problem but here they are for completness:
Source System Type: OPC DA
OPC Server Name: OPC Data Access 2.0 for ifix
Specification: DA 2.05A
Acquistion Mode: Synchronous
Read Source: PCoCache
Force Flat Namespace: False
Synchronous Read Source: Device
Acceptable Data Quality: Good
Activate Items: Both
Agent:
No Subcription Items
Communication: MII
Tag Query Cache Mode: Cache:

What happens if you try to add some Tags using the Subscription tab on the Agent Instance? Do you get the same behavior in the OPC Browser in PCo?

PCO 2.1 and PI Historiam

Dear all,
I have MII 12.2 recently installed and also PCO 2.1.
I want to display PI Historian data through an OLEDB connection as i was doing with the UDS before.
I have defined the connection in PCO successfully as Source System. Do i need to make any additional configuration in PCO? Create an agent?
Then when i go to the MII, in order to define the data server, which type i should use? OLED or PCO connector?
If i select PCO connector, the system is asking for a URL or select a registered PCO instance and i have no idead on what to define here.
I would thank any hint as I'm absolutely new with the PCO.
Thanks

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.

Edited by: Udayan Upreti on Sep 19, 2011 9:30 AM

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?
Regards,
Sam
