70 DC communications
error
COM, DC E There exists an abnormality in communications
between R/W Heads and DCs.
• Problem with positioning due to DC speed or
distance.
• Obstacles causing mis-operation.
71 Disagreement error VERIFY E Read or write processing could not be done
correctly.
72 DC not present NO DC E DC was not present within communications
range when execution of write or head
commands was attempted.
7A Address too high ADRS E An address has been specified which falls
outside the DC memory area.
7C R/W Head not
connected
R/W H E R/W Head is not connected.
7D Write protect error PROTECT E The production date (year, month, day) area or
the write protected area has been specified by a
write command.
• Host communications errors are errors which occur during communications
between the host computer and the ID Controller.
• Local communications errors are errors which occur during communications
between the ID Controller and R/W Heads/DCs.
• All
error data is stored in the ID Controller , and error codes and error messages
can be read using the Monitor Unit (see Section 4 Monitor Unit Operation ).
6-3-2 Host Communications Errors
The ID Controller can detect the six types of host communications errors given
above in the following way.
• Vertical parity and overrun errors are detected in character units, FCS errors
and frame length maximum errors are detected in frame units.
• When
one of the above errors is detected, reception of an invalid command is
assumed and processing of that command is not performed, and the error
response is returned immediately after recognition of a carriage return <>.
• For the frame length maximum error, when the 272nd character is received,
reception is interrupted and an error response is returned.
• If incoming data is suspended for two seconds while command reception is
underway,
a reception interruption error response is returned. When this hap -
pens, there is no carriage return, thus resulting in a format error.
