Analog input Slave Unit
The disconnection
indication does not clear.
The sensor is
disconnected.
Restore the sensor
connection.
Check the connected
sensor and input type.
Disconnection is not
detected.
Disconnection can not be
detected for ranges other
than 1 to 5 V and 4 to 20
mA.
Check that the input range
is correct.
A disconnection is
detected even though it is
not disconnected.
The connected sensor
does not conform to the
input range set on the
Unit.
Check the type of
connected sensor and the
range setting on the Slave
Unit again.
The user adjustment error
is too large.
Execute user adjustment
again.
The conversion cycle is
too long.
The number of AD
conversion points is set to
maximum (4 points).
Reduce the number of
points if some inputs are
unnecessary, and execute
conversion again.
User adjustment is not
accepted.
Attempted to make
adjustment with inputs
outside the compensation
range.
Enter a voltage (current)
within the compensation
range with the input
device and make
adjustment again.
If a voltage (current) within
the compensation range
cannot be entered, check
the method being used to
connect the input device.
Analog output Slave Unit
Cannot hold expected
outputs when
communications errors
occur.
The output value that is
set for communications
errors is incorrect.
Change the setting to hold
outputs for
communications errors.
The conversion cycle is
too long.
The number of DA
conversion points is set to
maximum (2 points).
Reduce the number of
points if some outputs are
unnecessary, and execute
conversion again.
User adjustment is not
accepted.
Attempted to make
adjustment with values
outside the compensation
range.
Use a voltage (current)
within the setting range to
make adjustment again.
If the final output cannot
be adjusted within the
correctable range, check
the method being used to
connect to the output
device.
