OmniServer Client & Software Connectivity Interfaces

The same as with the devices, OmniServer can support client connections using any and all of the standard client interfaces listed above simultaneously (i.e. you can have more than one client access OmniServer at the same time without any problems).

OmniServer Server Edition and the OmniServer Professional Edition give you access to the OPC UA Server interface, in addition to the other standard client interfaces.  See the link below for more detailed information:

OPC-UA provides a way to connect clients and servers in a secure manner, without relying on Microsoft DCOM . This is a big advantage because it means that you are no longer saddled with the headaches associated with having to configure DCOM. This is because DCOM plays no role in data transport.

OPC-UA can also allow users to make secure connections through firewalls and over VPN connections . In addition, it expands the ability to provide factory floor information to other business systems, as a result of the object-oriented model described above.

OPC UA was the result of several advancements and changes in the way data was commonly being accessed and exchanged. Some changes that lead to the need for a new architecture include:

• Microsoft's COM and DCOM (the basis for previous standards) were deprecated and are now considered legacy technologies.
• Web services gained importance in data exchange between machines and for communications to factory floor devices.
• Earlier specifications were decoupled and did not integrate well, e.g. items in a Data Access server could not communicate directly with items in an Alarms and Events server.

OPC UA is designed for exchanging information in an object-oriented manner, rather than as isolated data points. This increases the accessibility of your plant floor data by letting you re-use information stored in a common object. OPC UA also incorporates a service-oriented model, which increases interoperability with other platforms and greatly improves security (all without the headaches of DCOM).
