Is a status report required, "Yes/No".
Is a statistics report required, "Yes/No".
Linking a number of Masking Parameters (AND/OR)
For an AND operation, enter the parameter name at the "Masking Param. =" prompt.
This condition is OBLIGATORY for all of the selected points.
For an OR operation, enter an exclamation mark "!" before the parameter name. This
condition is NOT OBLIGATORY for all of the selected points.

1. Masking Param.=.: RSUP

Explanation
The exclamation mark (!) before the parameter OSV indicates that this is an "OR"
operation between two or more masking parameters, i.e. one OR the other limiting
condition must apply (RSUP=No OR OSV=Yes).
If there were no exclamation mark, it would be an "AND" operation, i.e. ALL limiting
conditions must apply (RSUP=No AND OSV=Yes).
In the above example the VISONIK DCS will process all of the points whose parameter
RSUP=No or whose parameter OSV=Yes.
In the case of parameters with numerical values it is recommended that small ranges
should be entered for the parameter value in order to take internal rounding differences
into account.
e.g. AI = 19.5 .. 20.5 instead of 20
