Setting History Data
(1) When creating screens with the Support Tool, use screen attribute desig-
nations to register history attributes and messages (within 24 characters) for
the screens you want to save in the history.
(2) Whenever the screen number registered for history attributes is desig-
nated by the host, the occurrence and message are saved in memory. The
capacity of the history is 1,023 screens in chronological order or 255 occur-
rences per screen in frequency order. The only things that can be recorded
are screen numbers and messages. History record data is backed up by a
battery, so, as long as the battery is installed, the contents will be retained
even when the power is turned off.
(3) Before beginning to record, initialize the history data by transmitting an
Initialize History command from the host, or by selecting Init. Hist. from the
Maintenance Mode. If the history data capacity is exceeded, newly occur-
ring history data will not be saved.
