KEPServerEx
After completing your work with the IOtoolKit, you will need to install the KEPServerEx OPC Server
Software and then configure KEPServerEx. OPC stands for OLE for Process Control, where OLE is the
acronym for Object Linking and Embedding.
The IOtoolKit CD (p/n 1075-0601) includes a free, unlicensed version of the KEPServerEx software,
related instructions, and prompts.
Note: The free unlicensed version of KEPServerEx [included on the IOtoolKit CD] supports up to three
hours of operation before it is necessary to re-boot the system. A licensed version of KEPServerEx
software, that provides continuous operation, can be purchased through IOtech. Contact
information is provided on the cover page of this document.
Install the KEPServerEx Software
1. Insert the IOtoolKit CD (p/n 1075-0601) into the CD drive.
Note: The CD should auto-start. If the CD does not auto-start, run the CD start.exe from the
Windows Desktop.
2. Browse to the contents of your CD drive.
3. Open the KEPServer folder.
4. Double click on disk1.
5. Click on setup.exe.
6. Follow the prompts to complete the installation.
7. From the Windows Start menu: select Programs, then KEPServerEX.
The program will now load.
Configure KEPServerEx
KEPServerEx configuration is discussed in help files that are included on the IOtoolKit CD
(p/n 1057-0601). Reference notes to those documents are provided below.
DASYLab can only recognize the short data format; thus, KEPServerEx must be
configured for short data format.
The scan rate must be specified for a fixed scan rate, not to transmit data only when a
change occurs.
Reference Notes:
Refer to the KEPServerEx Help document [located on the IOtoolKit CD] for information
regarding 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 <QuickClient>
button
• save the configuration for backup purposes
Refer to the EtherTRAK Help document [located on the IOtech Toolkit CD] for a list of
modbus addresses for each module’s channel type. Channel configurations [for specific
channels] require that the modbus address and the data format be specified.
After completing the KEPServer configuration, use the OPC <QuickClient> button to test all PointScan
modules and channel configurations.
