- 90 7.11 Job Setting - Actions
7.11.1 Setting items in Communication action
Variables can be used as component values for each action or as condition values
of [Select/Update/Delete conditions].
The following table lists data types of variables and those of assignable fields.
If the type of a variable does not match the data type of its substitution target field,
an error occurs, resulting in cancellation of job execution.
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.
