Protocol Requirements
In order to create a profile you must obtain protocol documentation from the device manufacturer. Many hardware vendors will provide the protocol documentation with the device or will post it as a .pdf on their website. Be sure to have the device model no. and determine whether your device has either a serial or Ethernet option.
| The U-CON's transaction editor uses a menu driven interface, which allows the configuration of read & write transactions (data packets) to establish runtime communications with the device. After you create these transactions upload them as Tags in our reliable and field proven OPC/DDE server. |

U-CON Support and Profile Development
Kepware will provide basic assistance with your U-CON project and can review the device protocol to determine if a profile can be created. Members of Kepware's U-CON Certified Developer program may be available for consultation and profile development for a fee. You can review and download submitted profiles at the U-CON Profile Exchange, search our database of System Integrators or contact Kepware Technical Support for assistance. If you are interested in becoming a Certified U-CON Profile Developer please submit this short form for additional information.

Creating Read / Write Transactions
The development of a custom communication profile begins by defining the tags or data that needs to be read from or written to a serial device. After the tags have been defined the next step is to define the transactions needed to communicate with the device. The transaction editor provides a wide range of tools and actions that can be used to build the messages that will be sent to a device. Additional actions allow the responses from the device to be processed and turned into tag data available to your OPC client applications.
Step 1: Defining Tags
The first step is to define the tags required by your OPC application.
Step 2: Defining the Transactions
The next step is to define the transactions that read or write data from your tags.
Step 3: Testing your Profile
Finally use the diagnostic view and OPC Quick Client to test your driver profile.
