4 RSLinx – Training Guide
RSLinx can transfer data to and from Allen-Bradley PLCs using common
Allen-Bradley communications devices such as the PCMK, 1784-KT board
or the 1770-KF2B module.
It supports the Allen-Bradley SLC-500, PLC-2, PLC-3, PLC-5, and PLC-5/250 families of
processors all in one package.
It is a complete communications software package, not requiring any external driver
software to operate - it is not a TSR (memory resident). It does all of the
communications work for commercially available DDE compatible Windows programs as
well as Windows programs that a user may design.
With RSLinx and a DDE compatible Windows application such as Excel, a user can
install, connect to a PLC, and be on-line collecting data in about 5 minutes.
In some ways, RSLinx is three drivers in one:
• It includes direct driver level access between the PLC and other Rockwell
Software products.
• It provides DDE (Dynamic Data Exchange) access to any DDE compatible
software program.
• In addition, it now supports OLE for Process Control (OPC).
