Restrictions On System Configuration - Omron CP1E Series User Manual

Allocation of I/O Words
Expansion Units and Expansion I/O Units are allocated I/O bits in the order the Units are connected
starting from the CP1E CPU Unit. When the power to the CPU Unit is turned ON, the CPU Unit checks
for any Expansion Units and Expansion I/O Units connected to it and automatically allocates I/O bits.

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 CP1E CPU Units.
Restriction on the Number of Connected Units
A total of up to three Expansion Units and Expansion I/O Units can be connected to a CPU Unit with
either 30 or 40 I/O points. Expansion Units and Expansion I/O Units cannot be connected to CPU Units
with 20 I/O points.
Restrictions on External Power Supply Capacity
The following restrictions apply when using the CPU Unit's external power supply.
AC-power-supply CPU Unit with 30 or 40 I/O Points
The power supply capacity is restricted for AC-power-supply CPU Units with 30 or 40 I/O points. It
may not be possible to use the full 300 mA of the external power supply, though a CPU Unit can con-
nect any CP-series Expansion I/O Unit or Expansion Unit.
The entire 300 mA from the external power supply can be used if Expansion Units and Expansion
I/O Units are not connected.
Refer to 2-4-1 External Power Supply Capacity When Expansion I/O Units or Expansion Units
are Connected for details.
AC-power-supply or DC-power-supply CPU Unit with 20 I/O Points
There is no external power supply on AC-power-supply or DC-power-supply CPU Units with 20 I/O
points.
