4. 1 1. Parameter Index Location
Set
1. Write the primary index value into R43,999.
2. Write the secondary index value into R43,998.
3. Write the desired format value into the appropriate format register.
4. Write the value to the appropriate parameter register.
Parameter-specific index method
4. 1 1. Parameter Index Location
Set
1. Write the primary index, secondary index, and data format values into the
appropriate format register.
2. Write the value to the appropriate parameter register.
Format words (R46,000 to R46,999)
Format words are unsigned integers that contain up to three values (described below).
The number of values used in the format words depends on the
Location
that is used.
4. 1 1. Parameter Index Location
is used to access the format words: Global Index Method or Parameter-specific Index
Method.
Global index method
4. 1 1. Parameter Index Location
Set
Only the final digit of the format word determines the decimal offset (below).
Parameter-specific index method
4. 1 1. Parameter Index Location
Set
All three decimal fields are used to determine the parameter value's primary index,
secondary index, and decimal offset.
Format registers
Each format register is made up of three decimal fields:
• Decimal offset
• Secondary index
• Primary index
The primary and secondary indexes correspond to those that are used by the parameter.
