Detailed Description
2.9 Sum offsets and setup offsets
Creating a new sum offset
If the compensation data set (x) does not yet exist, it is created on the first write operation to
one of its parameters (y).
$TC_SCPxy[ t, d ] = r.r
When working with setup offsets, "sum offsets fine" are written with the $TC_SCPx system
variables.
Note
When working with setup offsets, the data set for the setup offset is created when a data set
is created for "sum offset fine", if a data set did not already exist for [t, d].
Creating a new setup offset
If the compensation data set (x) does not yet exist, it is created on the first write operation to
one of its parameters (y).
$TC_ECPxy[ t, d ] = r.r
Note
When working with setup offsets, the data set for the "sum offset fine" is created when a data
set is created for setup offsets, if a data set did not already exist for [t, d].

; Parameter y of sum offset x is assigned the value "r.r.".
The other parameters of x have a value of zero.
; The value "r.r" is assigned to the parameter y of setup
offset x. The other parameters of x have the value zero.
