I/O Allocations to CompoNet Master Unit
Section 5-3

I/O Allocations to CompoNet Master Unit
The system allocates words in an Input Area and Output Area to the Smart-
Slice I/O Units using the node number of the SmartSlice I/O Terminal. These
words are in the I/O memory of the CPU Unit of the CompoNet Master Unit.
You can also use the CX-Integrator to set I/O allocations.
Note
You can also use Software I/O Allocation Mode to allocate words to a Dummy
Unit. A Dummy Unit is a SmartSlice I/O Unit that is not connected in the
SmartSlice I/O Terminal. Refer to
6-7 Software Setting of I/O Allocations
on
page 60 for more information.

Overview of I/O Allocations
This section gives an overview of I/O allocations to the CompoNet Master
Unit.
1.
Status of the CompoNet Communications Unit
The Status Word shows the status of the SmartSlice I/O Units in the
SmartSlice I/O Terminal.
2.
I/O Data for SmartSlice I/O Units
The system allocates the bits or words to the SmartSlice I/O Units in the
SmartSlice I/O Terminal in the same sequence as the unit numbers. It al-
locates lower bits first and words with lower addresses first.
