Appendix A.3. Extending the List of Show Attributes
The list of attributes and attribute states that the driver recognizes can be extended by modifying the configuration CSV file.
Appendix A.3.1. ShowResponse Attributes Driver Table
Column Title Function Legal Values
Protocol Specify protocol used Sim4100
sim4100_Attr_Name
The SHOW command response consists of a number of
attributes and their current state/values. This parameter
is used to add a new attribute to the table.
The exact character
sequence must be
specified. May include an
= sign.
sim4100_Attr_Offset
This parameter defines the offset in the Data Array where
the current state/value of the attribute with the name
defined above must be stored. Ensure there is sufficient
space for attributes with multiple values.
May not be zero.
sim4100_Attr_Method
This parameter selects the method for converting the
current state/value for storage in the Data Array. 1,2,3
May not be zero.
Appendix A.3.2. Show Response Attribute States Driver Table
Column Title Function Legal Values
Protocol Specify protocol used Sim4100
sim4100_Attr_State_Name

predefined attribute states. Define a state word such as ‘Normal’ and associate
a value using the ‘value’ parameter.
sim4100_Attr_State_Value
This parameter is the value to be
associated with the ‘name’
May not be zero.
The following example adds three attributes and 4 attribute states. If a device reports an attribute of ‘LIGHT STATE’ as
‘BRIGHT’ then the driver will load array element 32 with the value 41.
