Status Areas
A Temperature Input Unit has two status areas. The flags are turned ON and
OFF based on the threshold values set by the user for each function in that
Unit.
If any flag in a Status Area in the Slave Units connected to the Master Unit
turns ON, a corresponding status flag in the Master Unit turns ON. Bit 12 in
the Master Unit corresponds to the Warning Status Area and bit 13 corre-
sponds to the Alarm Status Area.
The Temperature Input Unit's status area information can be read by using the
CX-Integrator or explicit messages.
Warning Status Area
The Temperature Input Unit's Warning Status Area contains the following 16
bits. These bits indicate minor errors in the Unit.
Master Unit
The Master Unit has a Warning Status Bit and Alarm
Status Bit.
The status of each of these bits is an OR status of the
bits in the status area in the connected Slave Unit.
Transmitted to Master Unit
Temperature Input Unit
The Status Area in the Temperature Input
Unit has a Warning Status Area and an
Alarm Status Area.

Voltage drops below the voltage set as
the threshold for monitoring.
3
Unit Maintenance Flag
OFF: Normal
ON: Error (Threshold exceeded.)

tion Time exceeds the value set as the
threshold for monitoring.

Temperature Input Warning Flag
OFF: Within range (below set moni-
tor value)
ON: Out-of-range (equal to or above
set monitor value)
Turns ON when the temperature data
exceeds the displayable range or the
monitor value set for the comparator
function.
9
Cumulative Counter Exceeded Flag
OFF: Within range (below set moni-
tor value)
ON: Out-of-range (equal to or above
set monitor value)
Turns ON when the cumulative value
exceeds the set monitor value.
