All of these security features are easily configurable using a user friendly graphical interface and do not require a public certificate provider or access to the Internet. Apr 23, 2015 · Hi, I am using IDF for Splunk to retrieve kepware tags data for reporting where splunk shows me realtime as well as history data of kepware tags. can anyone please tell me where the Kepware history data is stored exactly which splunk shows. is it in Kepware only or in Splunk?. If you provide me backup data file path and name it will be highly appreciable. Thank you.
Another solution this days is Kepware Kepserver EX. It can act like OPCDA client direct on one node inside the 800xA system and act as OPCUA server to outside. This solution is much more secure but also takes a bit more time. Within the DCOM Configuration Manager, look within the main window and locate your OPC server. (RSLinx, Kepware, etc.) (This is the same window used for the OpcEnum step.) Right click on the OPC server and select properties. Set the Authentication Level to Default. On the client machine's fire wall allow port 135 incoming coneciton Note: For initial testing disable the firewall on both the server and the client .. Note down the user ID and password of the windows user account under which the opc server is running and create the same user name and account on the remote machine (This is to establish trust ...
The most common cause is a incorrect port specified by the client. It also can be caused by a firewall or anti-virus software. Be sure those 2 don't blocking any ports needed by sysaid.

This way, we don’t have to worry about DCOM issues since the OPC Client and OPC Server are combined. The only communication between these 2 nodes is through the Wonderware Suitelink protocol. As long as Port 5413 is open in any firewall, communication should be seamless from the Galaxy using the DDESuitelink object.

A default instance of SQL Server listening on the default port 1433 on Windows 2012 R2 server: In this scenario you need to ensure an exception is added to TCP port 1433 in the Windows firewall Open Windows firewall on the system hosting SQL server default instance and click New Rule under Inbound Rules.
A small paragraph in the catalog suggests that a Siemens OPC server (PC Access) will connect to the S7-200 Smart over TCP/IP; I would be enclined to believe that the connection to the Kepware OPC should be established without problem. Local Discovery Server (LDS) Overview. The UA Specifications Part 4 - Services and UA Specifications Part 12 - Discovery describe the purpose and operations of a local discovery server.
Verify that the server and client can connect to each other on the network and that port 135 is open (use telnet). If port 135 is not open, check for issues related to a firewall or other network restrictions. For more information, see the OSIsoft Knowledge Base topic titled “Configuring ports for DCOM for use with the OPC Interface. www.kepware.com 4 DCOM - Secure by Default 1. Overview This white paper intends to provide users with information and instruction on how to configure the Distributed Component Object Model (DCOM) for use with OPC clients and servers. The information discussed will include the following: •
Also, ensure your firewall is not blocking traffic on the port that KEPServerEX is using to communicate. Go to the OPC Connections > Quick Client in the Configure section of the Gateway, under the Kepware > Channel1 > Device1 folder, you will see the Tag folders.

DCOM Configuration. Dcomcnfg. Part 5. OPC and DCOM Configuration. Typical problems and solutions. The idea itself makes some sense; however, the reason why the cert has not appeared automatically in the KEPware server "rejected certs" is probably because the client cannot reach the endpoint, and that it is what has to be resolved first (or only). It should not be necessary to open a port other than the port indicated in the server's URL.
DCOM can use any port. Microsoft has a way to restrict the ports used by DCOM. OPC uses DCOM to talk to a program on a different PC. If your firewall does ip address translation (ie if it is a hardware firewall), then DCOM (and therefore OPC to a remote PC) will not work.

Nov 11, 2015 · All the remote sites are connected to a central firewall. The Kepware server is doing the same thing, connecting back up to the firewall via IPSec VPN. I can see pings across all remote sites so routing is good. I even went as far as allow all traffic for testing.
Windows Firewall Configuration When setting DCOM configuration and testing OPC Server for remote connectivity, it is recommended that Windows Firewall be temporarily set to 'Off'. After connectivity has been established, Windows Firewall should be re-enabled with OPC-specific exceptions added to allow for OPC Server connectivity. OPC UA communication takes place using various TCP/IP ports. To locate OPC UA servers on other hosts, OPC Toolbox uses the OPC UA Local Discovery Service for that host, which is hosted on port 4840. Every other OPC UA server on a host uses a different port for communication.
