OmniServer Download Version 3.5.0.0
(Updated 14 October 2024)

Your free trial download includes

• The full functionality of OmniServer including all client interfaces and client wedges.  One installer for all three OmniServer Editions.
• Fully functional without any tag or device count limitations.
• Flexible OPC DA Test Client is included for easily testing your OmniServer protocol (Connect your own HMI, SCADA, MES, Historian and other client applications later.)

If you are an existing license holder with a valid support and maintenance agreement, you can also use this download to update your current OmniServer installation.

To get started, we strongly recommend you review our OmniServer video tutorial resources, and if you are having problems, we strongly suggest you start with our Omniserver Troubleshooting Guide and Flowchart and other online resources. If you are still having problems with your trial, you can contact our support team for assistance. 

Your free trial has these limitations

• The OmniServer free trial runs for 2 hours at a time and must then be reset by restarting the OmniServer Poller process/service.
• At the end of each 2 hour period, any client connections to the free trial will be discontinued and have to be re-established after restarting the polling process/service.

Purchasing a license for the desired Omniserver Edition will remove these demo limitations and you can put your configuration built with the trial into production use.

If you are having problems, and you know the 2 hour timeout has not occured, we strongly suggest you start with our Omniserver Troubleshooting Guide and Flowchart and other online resources.
