7.11.4 Setting items in Operation action
Constants can be used for [Operation tag] and [Component] that are operands.
The following shows the constant types and values that can be entered in the
[Component] column.
Table 7.82 Constant types and values available for [Component]
Constant type
[Number]
[String]
[Date String]
Variables can be used for [Component] of [Substitution tag] or [Component] of
[Operation tag].
By using a variable, a value computed in [Operation action] can be assigned to a
database, or to a tag component (In the latter case, operation is performed based on
a value extracted from the database).
The following table shows the variable types and values that can be entered in the
[Component] column.
Up to 64 variables can be set for one job.
(1) A variable is valid only in a single job execution and is not held.
(2) The initial variable value before substitution processing is the numerical value
of zero.
(3) If a type that cannot be converted is assigned to a tag component when a
substitution tag is the tag component, "Type conversion to tag component
error" is displayed.
Check the source type and the data type of the tag component.
