System Configuration
Section 1-2
1-2-3 Restrictions on System Configuration
The following restrictions apply to the CP-series Expansion Units and CP-
series Expansion I/O Units that can be connected to CP1L CPU Units.
■
Number of Expansion Units and Expansion I/O Units Connected
A maximum of three Units can be connected to a CPU Unit with 30 or 40 I/O
points and one Unit can be connected to a CPU Unit with 20 or 14 I/O points.
■
Mounting Restriction
When connecting CP-series or CPM1A-series Expansion Units or Expansion
I/O Units to a CPU Unit with AC power, provide a space of approximately 10
mm between the CPU Unit and the first Expansion Unit or Expansion I/O Unit.
If sufficient space cannot be provided between the CPU Unit and the first
Expansion Unit or Expansion I/O Unit, use the PLC in an ambient temperature
of 0 to 50
°
C.
