KEPServerEX is somewhat unique in its approach to providing OPC connectivity for a number of devices. In most cases OPC servers are written as single function programs that can handle only a single device type or protocol at a time. The result is that multiple OPC servers are required to handle a range of devices and protocols. KEPServerEX is written as two separate components. The server component (KEPServerEX) houses all of the user interface and OPC technology. Device specific drivers plug into this server component. If only one communications driver could be plugged into the server at a time then we would have gained nothing. KEPServerEX allows you to use a number of communications drivers concurrently.
Notice in the figure below that we have configured KEPServerEX to communicate with Allen Bradley, General Electric, Mitsubishi and Siemens Devices using the one server interface. Also notice that you can configure multiple devices (Mitsubishi) under one channel.
