U-CON driver

U-CON is a universal translator between the proprietary serial world and OPC. With the U-CON driver, developers can easily create OPC data item tags that represent almost any value from the serial device. As with other OPC devices, tags can be read-only or read-write and consist of any data type.

The U-CON transaction editor makes this possible by allowing developers to create the command structure for a tag as a series of simple steps. For example, the screen shot in Figure 1 shows the command structure for reading a temperature probe. The transaction steps are generated using a menu system to create an easy-to-read state machine, as shown in Figure 2.
