Triggers for Starting
and Ending Trend
Data Collection
There are two ways of starting and ending trend data collection, as described
below.
Trigger Tags
Trigger tags can be used to start and end trend data collection according to
the status of the specified tags.
Set the tags as follows, depending on the type of tag data (contact ITEM or
analog ITEM):
Contact ITEM: Data collection starts and ends according to the ON and
OFF status.
Analog ITEM: Data collection starts when the tag value is equal to or
greater than the batch start value that has been set, and it
ends when the tag value is less than the batch stop value.
Batch Trend Screen Operations
Trend data collection can be started and stopped at any time from the Batch
Trend Screen.
Use the following procedure to start trend data collection.

collection conditions are already satisfied.)
