Megaplex-4100

Chapter 1 Introduction Installation and Operation Manual
System Functional Block Diagrams
The functions available from a Megaplex-4100 chassis depend on two factors:
• The type of CL modules installed in the chassis. The capabilities of each type
of CL module are described in the Common Logic (CL) Modules section on
page 1-18.
• The types of I/O modules installed in the chassis.
The resulting functionality is described by means of functional block diagrams:
