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.

Restrictions in the External Power Supply Capacity
The following restrictions apply when using the external power supply from a
CPU Unit with AC power.
CPU Units with 30 or 40 I/O Points and AC Power (CP1L-M @@ DR-A)
When CP1W or CPM1A Expansion Units or Expansion I/O Units are con-
nected to a CPU Unit with 30 or 40 I/O Points and AC Power (CP1L-M
@@ DR-
A), it may not be possible to use the entire 300 mA from the external power
supply due to restrictions in the power supply capacity. The entire 300 mA
from the external power supply can be used if Expansion Units and Expansion
I/O Units are not connected.
DeviceNet I/O
Link Unit CPM1A-DRT21 As a DeviceNet Slave, 32 inputs and 32 out-
puts are allocated. 200 g max.
CompoBus/S
I/O Link Unit CP1W-SRT21
CPM1A-SRT21 As a CompoBus/S slave, 8 inputs and 8 out-
puts are allocated. 200 g max.
