Types of error and error code
 Error code list
The following error codes may occur in the DL-PN1.
 DL-PN1
Error code Description Cause Actions
0 No error - -
51
Unassigned ID
error
The main unit assigned no ID
within 10 seconds after the
DL-PN1 had been started.
Check if the number of connected sensor
amplifiers exceeds the maximum number of sensor
amplifiers that can be connected to the main unit.
"Types and Number of Connectable Sensor
Amplifiers" (page 3)
Check the connection with the sensor amplifiers
and then turn the power on again.
If this error cannot be recovered, contact your
nearest KEYENCE office.
52
Start-time
communication
error
Communication between
sensor amplifiers ended
abnormally before ID
assignment completion.
Check the connection with the sensor amplifiers
and then turn the power on again.
If this error cannot be recovered, contact your
nearest KEYENCE office.
53
Unsupported
sensor amplifier
connection error
A sensor amplifier not
supported by the DL-PN1 is
connected.
Check the model of the connected sensor amplifier
and remove the sensor amplifier if it is not
supported by the DL-PN1.
54 Mixed model error
Sensor amplifiers outside the
specifications have a mixed
connection.
Check if the models are mixable.
55
Start-time
communication
error
ID number assignment is
successful but communication
failed during the subsequent
initial communication.
Check the connection with the sensor amplifiers
and then turn the power on again.
If this error cannot be recovered, contact your
nearest KEYENCE office.
56
Current limitation
error
The number of connected
sensor amplifiers exceeds the
allowable range.
Use sensor amplifiers within the allowable range.
57
Communication
error between
sensor amplifiers
An error occurred during
communication between
sensor amplifiers.
Check if there is a noise source around the DL-PN1.
If the sensor communication indicator is solid red,
turn the power on again.
100 System error The IP address is incorrect.
Contact your nearest KEYENCE office.
101 System error
A default gateway setting error
occurred.
102 System error
An attempt to read data in
EEPROM such as the MAC
address has failed.
103 System error
An attempt to start the protocol
stack has failed.
104 System error
An attempt to access
FlashROM has failed.
150 System error
The number of held IDs is
incorrect.
151 System error
The number of sensors is
incorrect.
152 System error An initial read error occurred.
