Command Block
Response Block
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.
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.
