System Configuration
Section 1-2

Restrictions on System Configuration
The following restrictions apply to the CPM1A Expansion Units, CPM1A
Expansion I/O Units, and CJ-series Units that can be connected to CP1H
CPU Units.
■
Number of Expansion Units and Expansion I/O Units Connected
A maximum of seven Units can be connected. If eight or more Units are con-
nected, an I/O UNIT OVER error will occur and the PLC will not operate.
■
Number of Words Allocated
The total number of either input or output words allocated to Expansion Units
and Expansion I/O Units must be no more than 15. Even if no more than
seven Units are connected, an I/O UNIT OVER error will be generated if 16 or
more input or output words are allocated.
■
Current Consumption
The total combined current consumption of the CP1H CPU Unit, Expansion
Units, Expansion I/O Units, and CJ-series Units must be no more than 2 A for
5 V and 1 A for 24 V and the total power consumption must be no more than
30 W. For CPU Units with AC power supply, the current consumption from
external 24-VDC power supply output must be included.
■
Number of CJ-series Units Connected
No more than two CJ-series Special I/O Units or CPU Bus Units can be con-
nected to the CP1H via a CJ Unit Adapter. No CJ-series Basic I/O Units can
be connected.
Example: Calculating the Limit on the Number of Connected Units
In this example, because each CPM1A-TS002 Temperature Sensor Unit is
allocated four input words, no more than three of these Units can be con-
nected. (Three Units
×
four words = 12 words.) After these have been con-
nected, there remain unallocated three input words and 15 output words. The
following table provides an example of Units that can be mounted in combina-
tion without exceeding these limits.
