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.
