Connectivity loss between PLC and Kepware

Hi Experts,
I m working on SAP PCo and PLC connectivity using Kepware.
I m trying to find out ways to find connectivity loss between
1) PLC and kepware
2) kepware and PCo
For 2nd approch,if connectivity loss is there then PCo instance will go in error state and using remote monitoring we can get alert.
But m not able to find any way for 1st approch.
If PLC connection lost then only tag quality in kepware is bad.
Is there any way in PCo expression editor to check tag quality so that i can trigger MII transaction?
Thanks in advance.
Regards,
Neha

To add to Hubrisnsx's comment ... are you provisioned Ethernet or MoCA for the WAN connection?
Edit: Never mind, I see in the first post you said MoCA. So, if the MoCA channel is staying up, then it sounds like it might be something inside the ONT.
Keep in mind that while some Verizon folks do drop by these forums from time to time, that this is primarily are user to user forum where customers can help one another.

I have siemens plc s7-300 and labview how can i communiction between plc and s7-300

Hi all good morning
iam new user for labview
now iam working one new projects with labview and s7-300 automation plc so how can i communication between plc and s7-300 using profibus or ethernet cables can any one help me with example
thanks
best regards
vijaynagar.

Dear vijaynagar,
it would be posible to communicate with our Comsoft PROFIBUS products like DF PROFI II, FNL or cRIO PB.
Please have a look at:
- DF PROFII: PCI, PCIe, C-PCI or PC104+ card with LabVIEW drivers: Link
- FNL: Ethernet/PROFIBUS Gateway: Link
- cRIO PB, C-Series module for National Instruments FPGA chassis: Link
The DF PROFI II can be bought directly from Comsoft, the cRIO PB can be bought from National Instruments.

Sven

(UIX XML) Sharing Connection objects between BC4J and custom java.

If I have a UIX XML page that contains some BC4J application modules, then in the event handler I call [public static EventResult handleMyEventEvent (BajaContext context, Page page, PageEvent event..) ], which in turn calls some java classes I have written that take a java.sql.Connection object and access the database doing some updates/inserts with this Connection object (via JDBC)....HOW CAN I USE THE SAME TRANSACTION AS WAS USED IN THE BC4J APPLICATION MODULE...i.e. CAN I SHARE THE CONNECTION OBJECT BETWEEN BC4J AND MY OWN JAVA CLASSES THAT USE JDBC?
What are the best ways to share such a transaction?
Thanks,
Paul.

Would it be easier to use a custom method on the bc4j Application module?
Take this scenario...
1. User opens UIX XML web page which opens a bc4j App Module..it has a VO based on all employees.
2. User presses the add button and a new employee is created (using the bc4j App Module).
(Notice: no commit yet!)
3. User presses the submit button...fires event REVIEW_SALARY.
4. This event is 'handled' in the event section of the UML XML...it calls:-
public static EventResult handleREVIEW_SALARYEvent (BajaContext context, Page page, PageEvent event)...
5. I now want to call a java class I wrote that computes an employees new salary and updates the employee record with this new salary. This update will fail unless it is part of the same transaction as the one used by the bc4j App Module (that inserted the new employee).
How best to proceed from here?
How about having a method on the bc4j App Mod's VO called 'reviewSalary'? Calling this would use the same transaction? I could then call my java class from within the VO's method? However do I still have the same problem in that my java class expects to be passed the connection object?
The approach you suggested previously seems a touch dangerous....in that these are not 'publically exposed'...and a new release of JDev may break my code.
Thanks,
Paul.

Connection failures between iMac and Macbook Pro

I'm experiencing frequent connection failures over my wi-fi network between my iMac and Macbook Pro on an otherwise strong, stable network. I can connect both of my computers to the Airport Time Capsule that I use as my wireless router without a problem, but for some reason I get connection failures between the computers say, 50% of the time. Sometimes it works fine, others it just hangs before giving me an error message. Any suggestions?
OS 10.9.3 on both machines
Apple Airport Extreme Time Capsule
iMac, 3.06GHz i3 (2010)
Macbook Pro Retina, 2.4 GHz i7 (1st Gen)

Hi jt in nyc,
Some checks:
Use Airport Utility on one of the machines
- Click on the Time Capsule ( enter password if prompted )
- Click on the Edit button
Under Airport Utility -> Wireless -> Wireless Options
Are the Time Capsule Wireless options set correctly?
- Country -> you know this, change if it is not
- 2.4GHz and 5GHz Channel set to Automatic
- Click on Cancel button to return to the Airport Utility graphic diagram.
- Click on the Time Capsule
- Click on your machines listed beside wireless clients
Are the machines reporting an excellent quality at different distances from the Time Machine?

Connecting OC48 Between ASR9K and ASR1K

Hi there.
I don't know the first thing about the WAN something like POS...
Now I'm facing some problem with connecting OC48(POS) between ASR9K and ASR1K.
There are new 9K and new 1K in same server rack for the test.
So i tried to test these for connecting OC48
9K and 1K is directly connected by OC48
9K : A9K-SIP-700 // SPA-2XOC48POS/RPR // SFP-OC48-SR
1K : ASR1000-SIP10 // SPA-1XOC48-POS // SFP-OC48-SR
After connecting these two devices directly, ASR1K shows the interface status is up/up
but ASR9K ... the interface status is down/down.
I didn't configure anything. Do i need to configure something ?
When i connected POS port 1 and POS port 2 directly in the same ASR 9K chassis, the interface is up/up
please help me out
Thank you in advance. :)

exactly, so the transmit side of the 9k needs to be connected to the receive side of the 1k.
the transmit side of the 1k needs to be connected to the receive side of the 9k.

Problem with Internet connection sharing between eMac and Powerbook G3

Hi,
I seem to be having a slight problem with internet connection sharing.
My eMac is the main machine with the internet connection, and its running 10.4.6, the Powerbook G3 is running 10.2.8.
I can connect them all up and get online with both, but I the problem I am having is when I turn the Firewall on on the eMac, the powerbook can't connect.
Is there anyway I can keep the Firewall enabled and still use internet connection sharing?

How do I know which ports the Powerbook is using?
Also I had web sharing enabled on the eMac and it made no difference at all.
Plus I don't know if this means anything to you, trying to decipher it myself, all I can make out myself on there is port 80.

Hi Yadagiri,
Please check the reply from Carlos in the below thread
Re: increasing heapsize of java on WINDOWS 2003
Also check your sm59 RFC destination, i guess there is some problem.
Delete AI_RUNTIME_JCOSERVER(RFC connection between the Java engine and the ABAP engine) and create it again.
Hope tht will resolve ur issue...

Testing SSL Connections, differences between ABAP and JAVA stacks

Hello,
   I am trying to test an outbound SSL connection to a partner.   I already have multiple outbound connections to many partners, but this new one is causing an issue.   Our firewalls between the two sites are opened as required, I verified that I can telnet to the 443 port of their sever.   I then attempted to connect to their URL, via a Java SOAP message, and it is rejected. Some kind of error regarding our handshake.
   In an attempt to troubleshoot the issue I entered their URL in SM59 as a HTTPS connection, tested it, it worked fine.   Which indicates to me that the ABAP side works fine.
   I do the same on the Java stack, via the SOA Manager: Destinations, and it fails.
"Error during ping operation: Error while silently connecting org.w3c.www.protocol.http.Http.Eception: Peer sent alert: Alert Fatal: unexpected message"
I was thinking that maybe the remote partner only allows specific types of SSL version connection, and the Java side is too low. i.e. the partner only allows TLS v1, and we are attempting to use SSL v2.    Is there a place to set this on the Java side? I know I can set inbound parameters on ICM via SMICM.
Any help or assistance would be most appreciated.
Thanks,
Michael Montone

Hi,
I suggest that you verify if you use the same release of the SAP Cryptolib for the ABAP and the Java stack.
This could explain a difference of support for SSL or TLS.

Olivier

Packet Loss between ASA and 871

We are running a Cisco ASA 5505 and remote clients are 871's. We currently use a EasyVPN configuration between the single ASA and our 13 871's.
Today (1) out of the (13) tunnels is experiencing packet loss. I have power cycles the broadband router on the 871 end and the 871 and the situation still exists.
Does anyone know what would cause this and how to troubleshoot it?
Thanks,
Jason

Have you contact broadband provider on the 871 side to rule out any issues on the link? what broadband ADSLAM pppoa? start first rulling out physical issues WAN interface, LAN interface stats and work your way up, is this is something that suddenly developped? from what you post indicates it seems this tunnel have been fine, it could be broadband link issues but fist investigate with provider to go the next step.
what do you see in 871 router logs in terms of links, turn on logging informational before staring debugg proceedures.

Connection mode between SAP and PI

Hi Experts,
i now have the below question.
we know normally there are three ways of connection between SAP ECC and PI.
1. proxy
2. RFC
3. IDoc
then what is the connection mode for these three connections?
eg. ABAP connection, HTTP connection, TCP/IP connection?

Hi Aditya,
As far as I know:
1. proxy    uses type 3 connection (ABAP)
2. RFC       uses type T connection (TCP/IP)
3. IDoc      uses type 3 connection (ABAP)
However, let us wait for the response of others.
Regards,
Mark

Connection lost between SA520 and WAP200

Hi guys!
I have a problem with the connection between a SA520 and a WAP200. Following scenario exists.
SA520:
two VLANs configured with following settings:
VLAN1: 192.168.167.1/24
VLAN2: 192.168.2.1/24
VLAN1 is for a dedicated network for some private computers connected to port one to four of the SA520
VLAN2 is for guests and bound to the optinal port of the SA520.
inter VLAN communication from VLAN1 to VLAN2 is activated.
One WAP200 is directly connected via ethernet cable to the optional port of the SA520 with following IP: 192.168.2.240/24. Two further WAP200 are existent and repeating the signal to increase the range of the W-LAN.
Now, if I ping from a computer within VLAN1 to the IP of the WAP200 (192.168.2.240) I get replies from that device. But after some amount of pings the connection between the two devices will be lost (no replies), and after 4 to 10 seconds the connection will be restored again. The weird thing is that I wasn't able to discover a reproducible scenario to hang the connection. Some time the connection between the two devices lives for ten minutes and some times it will break down after 30 seconds.
Does anybody have a hot tip where the fault for this behavior can be?
Thanks in advance and best regards

The Connector 1.0 spec does not provide any API's for testing a connection. The 1.0 RA's dont provide any testing capabilities to allow the container to do so. Even if some 1.0 RA's provide such capabilities, the container cannot rely on these non-standard features. So the container cannot really gaurantee that the connection handed to the application is good. There is no way to know unless the application uses it. The Connector 1.5 specification provides API's for test connections.

How to connect ratings between iPod and iTunes

Hey I just got an iPod and I want the ratings I set on the pod to update onto my computer. When I connect the iPod I can see the songs on the iPod have the ratings I set when I was using the iPod, but the original songs on the computer aren't updated.
Any advice?
Or do the ratings only flow one way? Thanks a lot guys,
Josh

It works for me; i.e. when I set ratings on the iPod, and then I sync the iPod, the ratings in the iTunes Library change to what I set on the iPod.
Maybe it depends on the iPod model?

Connection Error between ITS and SAP: R/3 system

Dear All,
Recently we have migrated our Backend SAP: R/3 Servers to AIX/Oracle platform. The server landscape is running on two application servers and one central instance with load balancing.
We have changed all RFC destinations from the SAP:R/3 and ITS side and tested the connection.
We are not able to login to backend SAP:R/3 server through ITS.
The following error appears
"Fatal Error!
The ITS failed to handle this request
The HTMLBusiness interpreter failed to interpret the template.
The internal error message is:

Hi saikat180965,
Might be the problem is being caused by missing templates. Please have a look in the ITS traces to get more information about the missing file.
