Measurement Computing PointScan Road Map rev.2.0 - Manual (Page 25)

Step 11) Start up the KEPServerEX Software
The KEPServerEX software is used to set up and implement an OPC server. This server automatically
polls the PointScan modules and updates its data base with the current value of the process variables
monitored by those modules. Information in that data base can then be accessed by compatible OPC
clients, such as DASYLab or Kepware’s Quick Client.
General information on KEPServerEX is available on the Kepware CD. Insert the CD in the drive and
let it auto-start as described in Step 10). Then click on the “Product Specifications” menu item and
select KEPServerEX from the list. The system will show you several pages of general information
about the features and operation of KEPServerEX.
For more detailed instructions on configuring KEPServerEX, close out the Product Specifications
window and click on the Menu button to bring up the first menu on the Kepware CD. Click on the
“Product Support” selection and you will see several useful documents, including a Quick Start Guide,
an Installation Guide, and a KEPServerEX Help Manual under the White Papers option.
To start up and run the KEPServerEX software, go to the Windows Start menu, select the KepWare
Products program group, and then click on KEPServerEX.
The following steps show how to configure KEPServerEX specifically for PointScan/100 and /200 type
modules. They include information on how to:
• add station names and channel tag names
• specify device IP addresses and channel Modbus addresses
• prove the IO communication with all devices using the OPC button
• save the configuration for backup purposes
Note: In any of the KEPServerEX configuration windows, you can always click on the
button for more information on how to fill out the forms.
Step 12) Configure KEPServerEX
Adding a KEPServerEX “Channel”
The first step in the configuration process is to create a new KEPServerEX “Channel.” Note that the
word “channel” in this context means a communications channel or driver, not a process input such as
a thermocouple input or voltage input channel. The steps are:
(a) Click on the “Click to add a channel” link in the upper left hand portion of the
KEPServerEX window.
(b) In the “New Channel - Identification” window either accept the default channel name, or
enter a new one, then click on . Note that the name must not exceed 256
characters.
TIP: Change the name to something other than “channel.” A meaningful
channel name will stop confusion from occurring when accessing the
actual channel tags through DASYLab. A good idea is to use a project
name, for example, “Test_Lab_Monitor.”
(c) In the “New Channel - Device Driver” window, make sure that the “IOtech PointScan
/100” device driver is selected. Then click on Next.
