60 Words Block Format for Mailbox In Message (Input Image)
When the
Block Transfer Size
=
60
, it takes three Output blocks to form one
complete mailbox message request. Each Output block will be responded to with
a corresponding Input block with the same ID number.
Note:
Since the same three
Output Block IDs
are always used for 60-word block format requests,
the
Input Block IDs
will always be the same three numbers, as well,
100
,
101
, and
102
.
