ture Input Units The status does not turn ON
even if the monitor value is
exceeded. • The required Analog Smart

tionally if the monitor value is
set to 0.
The following conditions apply
to Temperature Input Units
only.
Enable the required function.
Set the monitor value setting to
a value other than 0.
(Check the decimal point posi-
tion then set the monitor value
again.)
• The input's decimal point
position for a Temperature
Input Unit was in the wrong
place when the monitor value
was set.
Check the decimal point posi-
tion and enter the monitor
value again.
• The expected analog input
value is not received or the
expected analog output is not
output after changing the
input type, display mode, or

• The Unit does not operate as
expected after changing the
allocated I/O data or a func-
tion enable bit.
• The changes will not be
enabled until the power is
cycled or the CX-Integrator is
used to reset the Unit.
• Cycle the power or reset the
CX-Integrator.
