Upgrading for Existing License Holders

If you are an existing license holder with a valid support and maintenance agreement, you can also use this download to update your current TOP Server installation. To renew or re-instate your support and maintenance agreement, please contact us.

Your free trial has these limitations

• The TOP Server free trial runs for 2 hours at a time once communications to a device/system starts and must then be reset by restarting the TOP Server runtime service.
• There are no artificial limits that cause the ability to run for 2 hours at a time to end after a certain number of days.
• 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 runtime service.
• If you need a longer period trial or test license that won't time out after 2 hours, please contact us. 

Purchasing a license for the desired TOP Server driver, driver suite or plug-in will remove these demo limitations and you can put your configuration built with the trial into production use.
