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.
