PLCIO is a UNIX/Linux library that allows applications to communicate directly with a PLC. Using standard Ethernet or Serial connections, applications can read or write memory and data values on a PLC, or respond to messages sent by a PLC. PLCIO does not require any custom bus interface cards or external specialized drivers.

Enterprise applications that currently depend on PLCIO include warehouse management, ASRS, tracking/barcode, and a variety of embedded control systems. The common requirement in all these applications was to interface large, complex data systems with PLC automation technology.
