Special columns
The check-box column plays a special role in tabular views. A check box is
shown active/inactive if:
The value calculated from the rule operation is 'true' or 'false'
(comparison rules except 'true-false' and '&').
Example: ( '\\TABLE\\TOOL\\T\\?\\TL', '<>', '0', 'true', 'false' )
-> 'TL' <> '0' means "activated"
'TL' = '0' means "not activated"
A value that is permanently defined as 'true' or 'false' can be determined
(comparison rule 'true-false').
Example: ( '\\TABLE\\TOOL\\T\\?\\TL', 'true-false', '-1', '0' )
-> 'TL' = '-1' means "activated"
'TL' = '0' means "not activated"
Masking bits to a numerical value of "bit is set" or "bit is not set" results in
(comparison rule '&')
Example: ( '\\TABLE\\TOOL\\T\\?\\PLC', '&', '1' )
-> Masking bits to the integer value 1 and comparing it to the 'PLC' byte
results in:
Logical '1'. This means "activated."
Logical '0'. This means "not activated."
