7.11.1 Setting items in Communication action
Tag components 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 tag components and those of assignable
fields.
If the data type of a tag component does not match the one of its substitution
target field, an error occurs, resulting in cancellation of job execution.
The data type of a tag component will change through operation processing of a
job.
