7-15-1 Display History Record Function
The display history record function serves to record the order of display and dis-
play frequency of screens during operation. The recorded data can be displayed
and checked either from the System Menu or during operation.
Procedure for Using the Display History Record Function
The procedure for using the display history record function is as follows.
(1) [Setting the screen attribute]
When creating screens with the Support Tool, set the “History” attribute for
screens whose display history is to be recorded. For this setting, a character
string (“title”) can be registered to indicate the contents of the screen. Title is
up to 24 characters in length.
Only screens for which the “History” attribute is set are objects of the display
history record function.
(2) [Initializing the display history]
Before recording can be started, the display history must be initialized from
the System Menu of the NT31/NT31C to clear the past records.
(3) [Recording the display history]
Operate the NT31/NT31C as usual.
When a screen for which the “History” attribute is set is displayed during op-
eration, the time of display and number of times it has been displayed are re-
corded.
