Command/Response Reference Section 11-3
Note If this bit turns ON for the CS1W-ETN11 or CJ1W-ETN11, the Ether-
net Unit has malfunctioned.
Address Mismatch
The address conversion method was set for automatic generation, but the
node number 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.
Total Number of Packets
Received (Response)
The total number of packets received by the Ethernet Unit is returned.
Total Number of Receive
Errors (Response)
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, and CRC errors.
Total Number of Packets
Sent (Response)
The total number of packets sent by the Ethernet Unit is returned.
Total Number of Errors
Sent (Response)
The total number of packet errors detected while the Ethernet Unit was send-
ing is returned.
Total Number of Send
Collisions
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.

Parameters
Test Data (Command,
Response)
This command specifies the data to be sent to the specified nodes. Up to
1,998 bytes can be specified. The response sends back data identical to the
data specified in the command. An abnormality is assumed if the data
returned in the response differs from the test data sent.
Precautions
The test destination node is the destination node specified in the CMND(194)
instruction operands.
