5-1
Status Areas
An Environment-resistive Slave Unit has two internal status areas: the
Generic Status Area and the I/O Status Area. The status flags in these areas
are turned ON and OFF based on the threshold values set by the user for
each function in that Unit.
5-1-1
Generic Status Area
The Environment-resistive Slave Unit's Generic Status Area contains the fol-
lowing 16 bits. These bits indicate minor errors in the Unit.
5-1-2
I/O Status Area
The I/O Status Area for an Environment-resistive Slave Unit consists of the
following 8 bytes (64 bits). The I/O Status Area indicates the short-circuit and
disconnection error status for each terminal.

Power or Load Short-circuit
Detection Flag
OFF: Normal
ON: Short-circuit
Turns ON when there is a
short in the power supply or
load connection to the con-
nected devices, including wir-
ing mistakes and connected
device failure.
05
Disconnection Flag
OFF: Connected
ON: Disconnected
Turns ON when the sensor
power supply is not connected
or the load is disconnected
due to a wiring error, failure in
the connected device, etc.
