saved when the Tuning Screen is closed.
Note With CX-Process Tool version 3.2 or higher, up to four Tuning Screens can be
opened at the same time. Opening more Tuning Screens, however, will increase
the communications load and can cause large errors in the data monitoring/log-
ging refresh cycle.
Data logging is started when the Tuning Screen is opened.
The following ITEM data is logged for each function block in the Tuning Screen.
