Appendix 11 Target List and Operation Details of the Device/Label Access Service Processing Setting
941
A
Execute END Processing between Programs
This setting is useful to give priority to the device/label access service processing in a system with a large number of
programs. Because operations such as access to devices are performed between program executions and during the END
processing, requests as many as the number of programs can be processed during a single scan. As a result, it can reduce
the response for the device/label access service processing.
Ex.
When "Execute END Processing between Programs" is enabled
(1) Synchronization with program is unnecessary.
(2) Requests for operations such as access to devices are processed between program executions and during the END processing.
