Appendix 2  Compar

ison with a Single CPU System

  

This section describes comparison between a single CPU system and multiple CPU system.

*1

"Number of CPU modules" indicates the number set in "No. of PLC" of PLC parameter ("Multiple CPU Setting").

*2

When a module occupying two slots is mounted, the maximum number of mountable I/O modules is the number 
obtained by "25 - (Number of CPU modules + 1)".
When a module occupying three slots is mounted, the maximum number of mountable I/O modules is the number 
obtained by "25 - (Number of CPU modules + 2)".

*3

If a Motion CPU or PC CPU module is used in a multiple CPU system, the Q3RB, Q6RB, and Q6RP cannot be 
used.
