How does OmniServer communicate with my devices?

OmniServer can communicate with any device connected to the computer via RS-232, RS-422, RS-485, TCP/IP, and LPT. Three flavors of TCP/IP are supported (TELNET, TCP, and UDP).

Is there a limit to the number of devices?

OmniServer can also support all the above mentioned devices simultaneously, so there is never a problem with mixing or matching devices. Up to 512 devices and topics can run at one time (although you are limited on the resources available on the computer).

Can I talk to more than one different type of device? For example, can I talk to a weigh scale, a barcode reader, and a PLC, all at the same time?

Yes. Other than the physical limits mentioned above, there is no limit to the different types of devices to which you may talk at any one time with OmniServer.

How do I get the data from OmniServer to my application?

OmniServer Server Edition and the OmniServer Professional Edition supports the following transports:

• OPC Data Access 2.x
• DDE (CF_TEXT)
• Advanced DDE
• Packed DDE
• WonderWare's Suitelink

OmniWedge supports the Keyboard Wedge where data can be sent from the your device directly to any Windows program that can support keystrokes.

OmniServer Professional Edition additionally supports the following wedges:

• Keyboard Wedge
• Database Wedge
• File Wedge

Can I use all the client transports listed above at the same time, as I can with the devices?

As with the devices, OmniServer can support all the client transports listed above simultaneously, so you can have more than one client access OmniServer without any problems.
