Total Number of Errors Sent (Response)

Total Number of Send Collisions (Response)

Address Disagreement

The address conversion method was set for automatic generation, but the node address and the last byte of the local IP address do not agree, or other host sections are 0.

EEPROM Error

An error occurred in the EEPROM memory in the Ethernet Unit.

The total number of packets received by the Ethernet Unit is returned.

The total number of errors detected while the Ethernet Unit was receiving is returned. The types of error detected are short packet errors, alignment errors, CRC errors, frame length errors (received frame: 1,515 bytes or more), and communications controller overflow errors.

The total number of packets sent by the Ethernet Unit is returned.

The total number of packet errors detected while the Ethernet Unit was send- ing is returned.

The number of packets damaged by 16 collisions with data from other nodes during Ethernet Unit transmissions.

Precautions

Counting of the total number of packets received, total number of receive errors, total number of packets sent, total number of errors sent, and total number of send collisions is discontinued when the counted value reaches the maximum value.
