The display history function is a function whereby the display of each screen dis-
played during operation is recorded in order of display occurrence and order of
display frequency. The maximum number of displays that can be recorded is
1,023 for recording in order of display occurrence and 255 for recording in order
of display frequency. Once these limits are reached, no more records can be
stored, and so the records must be periodically initialized (deleted).
The display history data memory can be initialized by a command given from the
PC (page 241).
When the display history data memory is initialized, the alarm history memory is
also initialized.
Using the System Menu, initialize the display history data memory by following
