Troubleshooting Section 12-2
Slave Units with
Power Short-circuit
Detection Function The short-circuit detection sta-
tus does not turn OFF after a
power short-circuit has been
detected, even though the
error has been fixed. The status will not turn OFF
until the power for the node
where the error was detected
is reset. Cycle the communications
power after fixing the error.
Slave Units with
Unconnected Line
Detection Function The Unconnected Line Detec-
tion Status Flag turned ON for
an unused input. Unconnected line detection is
enabled for an unused input. Disable unconnected line
detection for that input.
The Unconnected Line Detec-
tion Status Flag turned ON
even though the sensor power
supply was connected. Current consumption is low.
(Output current: 3 mA max.) Disable unconnected line
detection for that input (so that
the unconnected line detec-
tion function does not operate.)
The short-circuit detection sta-
tus does not turn OFF after a
unconnected line has been
detected, even though the
error has been fixed. The status will not turn OFF
until the power for the node
where the error was detected
is reset. Cycle the communications
power after fixing the error.
Slave Units with Load
Short-circuit Detec-
tion Function The short-circuit detection sta-
tus does not turn OFF after a
load short-circuit has been
detected, even though the
error has been fixed. The status will not turn OFF
until the power for the node
where the error was detected
is reset. Cycle the communications
power after fixing the error.
Slaves with Discon-
nected Line Detec-
tion The Disconnected Line Detec-
tion Status Flag turned ON for
an unused output. Disconnected line detection is
enabled for an unused output. Disable disconnected line
detection for that output.
The Disconnected Line Detec-
tion Status Flag turned ON
even though the external load
was connected. Current consumption is low.
(Output current: 3 mA max.) Disable disconnected line
detection for that output (so
that the disconnected line
detection function does not
operate.)
The short-circuit detection sta-
tus does not turn OFF after a
load short-circuit has been
detected, even though the
error has been fixed. The status will not turn OFF
until the power for the node
where the error was detected
is reset. Cycle the communications
power after fixing the error.
Analog I/O Slave
Units and Tempera-
ture Input Units The status does not turn ON
even if the monitor value is
exceeded. • The required Analog Smart
Function is not enabled. The
status will be OFF uncondi-
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
unit.
• 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.
