VMS Interface to Allen-Bradley® PLCs
Salem Automation, Inc.'s ABNet Software allows direct communication from VMS applications on physical or emulated VAX, AlphaServer, HP® Integrity™ platforms to Allen-Bradley PLCs via direct Ethernet connection or via ControlLogix® DHRIO Gateway to Data Highway Plus™. Supported Allen-Bradley PLCs include ControlLogix, CompactLogix™, PLC-5® and SLC™.
The ABNet interface can be called from a user’s C or FORTRAN program. ABNet follows the Rockwell Interchange VMS call format so that Interchange can be replaced with ABNet by just linking against the ABNet libraries. No programming changes or recompile required!
