The total number of packet errors detected while the Ethernet Unit was sending
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,

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 spe-
cified in the command. An abnormality is assumed if the data returned in the re-
sponse differs from the test data sent.
The test destination node is the destination node specified in the CMND(194)
instruction operands.
Always specify the unit address of the Ethernet Unit in the CMND(194) instruc-
tion.
