Whenever the screen number registered for history attributes is designated
by the host, the occurrence and message are saved in memory.
•
The capacity of the history is 256 screens.
•
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 lithium bat-
tery is installed, the contents will be retained even when the power is turned
off.
•
Before beginning to record, initialize the history data by transmitting an Ini-
tialize History command from the host, or by selecting Init. Hist. from the
Maintenance Mode.
•
If the history data capacity is exceeded, newly occurring history data will not
be saved.
