ZCDG Data Definitions
ZCDG-TKN-DIAG-NEW-UPDATE 
ZCDG events include this token to specify the new data that replaced the old as part of 
an UPDATE operation. The value of the token is a variable-length string. The length of 
the string, expressed in bytes, is stored in the first byte of the string, which is not 
included in the length computation. The token might appear more than once if the data 
is longer than 255 characters.
ZCDG-TKN-DIAG-OLD-UPDATE 
ZCDG events include this token to record old data that has been replaced as part of an 
UPDATE operation. The value of the token is a variable-length string. The length of the 
string, expressed in bytes, is stored in the first byte of the string, which is not included 
in the length computation. The token might appear more than once if the replaced data 
is longer than 255 characters.
ZCDG-TKN-DIAG-PHYS-ADDR 
ZCDG events include this token to convey the physical address of a controller.
This token is of type ZCDG-TYP-DIAG-PHYS-ADDR, which is based on the structure 
ZCDG-DDL-DIAG-PHYS-ADDR: 
Z-PRIME
contains the primary controller’s physical address.
