Code

Description

Breakpoint in an ISR.

The error is logged, and the ISR context resets the device. Post-reset the

error is detected and the device’s state is changed to hard-offline. This is to
prevent a possible endless repetition of this condition.

System Image Write Protect.

Writes to the system image are trapped, the error is logged, and the device

resets.

129

Bad event.

This run-time error is checked only in the development environment. This
error could occur if the network configuration is invalid, if the network

management tool is malfunctioning, or if the Neuron Chip firmware image

is corrupted. If this error occurs, try reloading the device.

130

NV length mismatch.

This error may occur rarely due to network transmission problems. The
length of the data in a network variable update message is inconsistent

with the length expected by the device. Rebuild and reload the images if

this error continues to occur.

Note this error does not get set in conjunction with the change of a network

variable type for a NV of changeable type. However, if such type change is

performed in an inappropriate manner, this error might be logged upon the
first arrival of the incorrectly sized network variable data.

131

NV message too short.

This error may occur rarely due to network transmission problems. This

error could occur if a network message is corrupted.

132

EEPROM write failure.

This error may occur rarely due to Neuron Chip, transceiver, or application
failure.
This error occurs if too many erase/write cycles have been performed on the

EEPROM or flash memory. Up to 10,000 erase/write cycles per byte can be
performed in the on-chip EEPROM. This error will also be logged if an

EEPROM write is attempted when a device is online and has EEPROM

locking enabled.

133

Bad address type.

This error could occur if the network configuration is invalid, if the network

management tool is malfunctioning, or if the Neuron Chip firmware image

is corrupted. If this error occurs, try reloading the device.
