2 Limits Limit value MIN, limit value MAX
Default: Empty
The limit values are separated by a comma. Limits can be specified for types I, C and R
in decimal formats or as characters in the form "A", "F".
Toggle field List with predefined entries in the I/O field: The list starts with a * and the entries are
separated by commas. The entries can be assigned a value.
For the toggle field, the entry for the limit is interpreted as a list. If only one * is entered,
a variable toggle field is created.
Default: none
Table identifiers Identifiers of a table containing NCK/PLC values of the same type, which can be
addressed via a channel block. The table identifier is differentiated from limits or toggle
fields by the addition of a % sign in front of it.The file containing the table description can
be specified by adding a comma after the identifier and then inserting the name of the
file.
3 Default setting If a default setting has not been configured and no system or user variable has been
assigned to the variable, the first element of the toggle field is assigned. If no toggle field
has been defined, there is no default setting, i.e., the status of the variable is "not
calculated".
