■ CP-series PLCs
■
CP1E CPU Units with 20 Points
There are no specific restrictions.
■
CP1E CPU Units with 30 or 40 Points
Normally, only one device can be connected to pin 6 (5-V power supply) on
the connector for the built-in RS-232C port or the connector for the CP1W-
CIF01 RS-232C Option Board of a CP1E CPU Unit. If two devices are con-
nected to one CPU Unit, a maximum of two Expansion Units can be con-
nected.
If only one device is connected to one CPU Unit, the normal number of CP-
series Expansion I/O Units and Expansion Units can be connected. For CP1E
CPU Units with AC power supply, however, it may not be possible to use the
external power supply up to 300 mA. If Expansion I/O Units and Expansion
Units are not connected, the external power supply can be used up to 300
mA.
For details, refer to the manual for the PLC.
■
CP1H CPU Units
Before performing operation, check that the current consumption for the entire
system is within the specified range for the CPU Unit.
■
CP1L CPU Units with 14, 20, 30, 40, or 60 Points
All CP-series Expansion I/O Units and Expansion Units can be connected.
For CP1L CPU Units with AC power supply, however, it may not be possible to
use the external power supply up to 200 mA.
If Expansion I/O Units and Expansion Units are not connected, the external
power supply can be used up to 200 mA.
For details, refer to the manual for the PLC.
