140 CPU 651 x0 Product Overview
General 
Description
The Quantum-140 CPU 651 x0 module (see p. 23) is among the newest in a series 
of Quantum processor modules. It combines standard PLC functions with the 
diagnostic possibilities of a Web server. The 140 CPU 651 x0 communicates using 
an RJ-45 connection.
The 140 CPU 651 x0 module is in a double-width standard Quantum housing, which 
requires 2 sequential slots in a Quantum rack. Its server functions are diagnostic 
only, so use software to configure services.
