ABNet allows direct communication from a VMS platform such as a VAX, Alphaserver, virtualized VAX or Alpha or HP Integrity system running VMS to a variety of Allen-Bradley ControLogix PLCs via direct Ethernet connection or via ControlLogix DHRIO Gateway to Data Highway PLUS. Allen-Bradley PLCs ControlLogix, CompactLogix, SLC, and PLC 5 PLCs are supported.
The ABNet interface can be called from a user’s C or FORTRAN program. ABNET follows the Rockwell Interchange for VMS call format so that Interchange can be replaced with ABNet just by linking against ABNet libraries - No programming changes or compiles required! ABNet support many of the DTL Interchange calls, and additional calls can be added as needed.
