Alarm Status Area
The Bit Slave Unit’s Alarm Status Area contains the following 16 bits. These
bits indicate serious errors in the Unit.
Note
Bit Slave Units with Compact Connectors support only the EEPROM Data
Error Flag.
9-2
Allocating I/O Data
Bit Slave Units are allocated node address areas in units of two points (two
bits).
• Input Units and Output Units
Units with two points are allocated two bits (the node address set for the
Unit).
Units with four points are allocated four bits (the node address set for the
Unit and the next node address area).
• I/O Units
Units are allocated four bits (the input and output node address areas).
