AMB
Red LED is ON.
(Diagnosis is
activated)
Analogue input or output
device power supply is
short-circuited.
Check the parts with error by using the LED display,
unit diagnostic data, CoE or web server.
Re-wire the short-circuited part, or check if the cable
and the analogue input/output device are normal.
0 and 1 red
LEDs are ON.
Input value exceeds the
upper limit of the range
when the range is set to
current input type.
Check the following when the range of the Analogue
input unit is set to current input.
(1) Set the input value of the analogue input device so
that it does not exceed the upper limit of the range.
(2) Voltage is input from the analogue input device.
Ensure the range of the input unit matches the
range of the input device.
Red LED is
flashing.
(Diagnosis is
activated)
(1) Input value exceeds
the upper or lower limit
of the range.
(2) Input or output value
exceeds the upper or
lower limit value (the
limit is set by user).
(1) If the input value from the analogue input device
exceeds the upper or lower limit of the range,
select the appropriate range so that the input value
is within the range. Or invalidate diagnosis.
(2) If the input (output) value from the analogue input
(output) device exceeds the upper or lower limit of
the user set value, adjust it so that the input
(output) value is within the range of the user set
value. Or invalidate diagnosis.
All red/green
LEDs are
alternately
flashing.
An internal memory error
occurred in the Analogue
input/ output unit.
Turn OFF the power for the unit, and then turn it ON
again. If the error is not eliminated, stop the operation,
and contact SMC.

L#B1
Red LED is ON
(C/Q or P24)
(Diagnosis is
activated)
Short circuit of L + power
supply, C/Q terminal, or
P24.
Check the parts showing an error using the LED
display, diagnosis data, CoE or web server. Re-wire
the short-circuited part, or check if the cable, IO-Link
master, and IO-Link device are normal.
All red/green
LEDs are
alternately
flashing.
An internal memory error
has occurred in the IO-
Link master unit.
Turn off the power to the unit, and then turn it on
again. If the error is not eliminated, stop using the
product, and contact SMC.

DFB
Red LED is ON.
Short circuit of power
supply.
Check the parts showing an error using the LED
display, diagnosis data, CoE or web server.
Re-wire the short-circuited part, or check if the cable
and the input device are normal.
Red LED is
flashing
Frequency count value
(value set by user) has
exceeded the upper or
lower limit.
If the frequency count value exceeds the upper or
lower limit of the range, adjust it so that the count
value is within the range of the user set value.
