Chapter

Testing KEPServer Communications

Objectives

This chapter shows how to test KEPServer communications on a

development computer to verify your project configuration and tags.

Use the OPC Quick Client

Included with the KEPServer server installation is a simple tool for

testing OPC tags called the OPC Quick Client. When you create a

new KEPServer configuration, there are several system and

communications tags that are also created. In this section, you'll verify

communication with the tags you’ve created before incorporating

them into an HMI project.

1. Select Tools>Launch OPC Quick Client from the main menu. Or

click on the OPC Quick Client icon.

2. Highlight the name of the device that you plan to test in the left

pane. This will display the tags that you have created in the right

pane.

3. Right-click the tag in the right pane that you plan to test, and

select Synchronous Write.
