Abstract
A universal network adapter for a control system provides an appliance receiving a user selection of network cards for different proprietary network types and an internal interpreter running custom scripts downloadable to the appliance to map the network protocols of the different networks to a single common network communicating with the programmable controller. A buffer table interposed between the networks provides for a consistent ordering of data transfer in separate input and output sessions. Configuration data may be held by the appliance to configure the networks and the devices using the same scripting translation.
