21 Uses Rating Table Object This parameter has rating-dependent defaults and limits that can be obtained from the Rating Table Object. The
Offline Read Full includes the default value for the smallest rating and limits. These limits accommodate the full
range of values that are allowed in the family of devices using this particular combination of Family Code and
Config Code. The Online Read Full includes the rating-dependent default and limit values for this particular
combination of Family Code, Config Code, and Rating Code.
22 Writable Referenced
Parameter
This bit must be zero unless the parameter is an Extended Parameter Reference. If the parameter is an Extended
Parameter Reference, then:
0 = The referenced parameter can be read-only or writable.
1 = The referenced parameter must always be writable (including while running).
23 Disallow Zero This bit must be zero unless the parameter is an Indirect Selector or Extended Parameter Reference. If the
parameter is an Indirect Selector or Extended Parameter Reference, then:
0 = Allow zero
1 = Disallow zero
If this bit is cleared, indicating that a value of zero is allowed. The device must support the ‘Zero Text’ parameter
attribute so that a software tool or HIM can obtain text from the Zero Text parameter attribute.
If this bit is set (indicating that a value of zero is disallowed), a software tool or HIM does not allow you to enter a
value of zero.
24 Datalink Out This bit is used by offline tools and indicates a datalink Out parameter. Set bit 20.
25 Datalink In This bit is used by offline tools and indicates a datalink In parameter. Set bits 20 and 22.
26 Not Writable While I/O Active This parameter cannot be written if the I/O data being exchanged between the Host and the peripheral is valid.
27 Command Parameter This parameter commands the drive to complete and action, such as ‘Reset Defaults’ or ‘Autotune’, and then
returns to a value of zero. Offline software tools do not allow setting this parameter to anything other than a
value of zero. If an offline file contains a Command Parameter with a nonzero value, the offline software tool
changes the value to zero. Command parameters cannot have values that do not return to zero.
28 Current Value Is Default This bit identifies a parameter that does not change if a ‘Reset Defaults’ is commanded. For example, if a drive
contains a Language parameter that is set to German, setting defaults leave the parameter set to German.
Likewise, if the parameter is set to French, setting defaults leave the parameter set to French.
29 Use Zero Text If the ‘Disallow Zero’ bit is set, this bit must be cleared. If the ‘Disallow Zero’ bit is cleared, then:
0 = Use Disabled Text parameter class attribute.
1 = Use Zero Text parameter instance attribute.
