The following checklist provides information that you can use to help you get started with installing the Tetra UNICORN Agent. For more information, see the latest Tetra UNICORN Agent installation guide.

Pre-Installation

Hardware

[ ] Make sure that the Agent can be installed on the same machine as the UNICORN client.

📘

NOTE

The host machine should not be used by the scientist for experiments at the same time. When the Agent is running, they might interfere with each other.

[ ] Make sure that the hardware is compatible with the UNICORN client.

Software

[ ] Make sure that UNICORN Software is installed (v6.x or v7.0-v7.8).
[ ] Install .NET Framework 4.8. Talk to your customer success manager (CSM) to learn how to install this.
[ ] Get the latest UNICORN Agent installer. Talk to your CSM to learn how to get this.
[ ] Verify that the UNICORN HDA Service is up and running in Windows Services.

[ ] Verify that the OPC Component is installed.

Optional Step: Install the OPC Core Components Redistributable

If the OPC Core Components Redistributable is NOT installed, do the following:
[ ] Install the OPC Core Components Redistributable from the UNICORN Installation package (DVD).
[ ] Install the OPC Component from the Tetra UNICORN Agent Installation folder. To do this, make sure the following two components are enabled/installed:
[ ] Component #1: Enable .NET 3.5 on the Windows Machine (in Windows Features).

[ ] Component #2: Visual C++ Runtime (2015-19). This can be downloaded from MSDN. Search the keyword Visual C++ Runtime (2015-19).

Required Step: Verify OpcEnum and Uncheck Logon for HDA Clients

[ ] After the OPC Core Component is installed and the service running, verify that the OpcEnum is up and running (check Windows Services).

[ ] Uncheck Logon required for HDA clients. You can find this in UNICORN Administration → Tools → Options → OPC Settings.

📘

NOTE

You must turn off Logon required for HDA clients for testing the HDA connection. However, you can turn it back on later, if you want the Agent to access UNICORN by using a user account. For more information, see Passing User Credentials (HDA Logon Required).

Installation

[ ] If this is an upgrade, review the upgrade instructions to make sure that you've completed the steps involved with preparing for and completing an upgrade.
[ ] If you're installing the Agent for the first time, double-click the Agent Installer to proceed with the installation. For more information, see the latest Tetra Unicorn Agent installation guide.
