HOST
The Ethernet Unit will output error status to the following word in the CIO Area
of the CPU Unit. This information can be used in troubleshooting errors.
Word = CIO 1500 + (25 x unit number) +18

Status Manipulated by
The IP address is set incorrectly.
The node address set on the rotary
switch on the front of the Unit does not
agree with the host ID in the IP address.
This probably can occur when the
address conversion method is set for
automatic address generation.
The Unit operation mode change function
is in effect.
