Allocating I/O Data
Section 5-2
Alarm Status Area
The Digital I/O Slave Unit's Alarm Status Area contains the following 16 bits.
These bits indicate serious errors in the Unit.
5-2
Allocating I/O Data
Input and output areas in I/O memory in the Master Unit are allocated to the
I/O data of Word Slave Units in a CompoNet Network. Node address areas
are allocated in order of node addresses for Slave Units of the same type. In a
CompoNet Network, Units are allocated node address areas of the size
required for each Unit, based on the node address set for the Unit.
5-2-1
Data Allocation for Word Slave Units
Word Slave Units are allocated node address areas in units of 16 points (one
word).
• Units with 8 inputs or outputs are allocated one word (the node address
set for the Unit).
• Units with 16 inputs or outputs are allocated one word (the node address
set for the Unit).
• Units with 16 I/O points (8 inputs and 8 outputs) are allocated two words
(the node address set for the Unit). The data is allocated to the lower
bytes of the words, and the upper bytes remain unused.
