This function displays a history of the key stroke and signal operations,
performed by the CNC operator, when a failure or CNC alarm occurs.
The following history data is recorded:
(1) MDI key operation sequences
Example: A to Z, <POS>, <PAGE ↑>, [SF1]
(2)On/off status transitions of selected input and output signals
Example: G0000.7
↑ , SBK ↑
(3)CNC alarm information
Example: P/S0010
(4)Time (date, time) stamp
Example: 01/01/20
09:15:30
The history data can be read or written to an input/output device.
Setting bit 4 (OHS) of parameter No. 3206 to 1 enables operation history
signals to be selected as parameters and signal selection data to be
input/output (read/punched) as parameters. In this case,
selecting/deselecting these signals on the operation history signal
selection screen causes the corresponding parameter values to change
automatically. Changing the parameter values also changes the displays
on the operation history signal selection screen.
The input/output signals selected as operation history targets are
displayed on the ”operation history signal selection screen.” Input/output
signals can be selected as operation history targets on the ”operation
history signal selection screen” and, if bit 4 of parameter No. 3206 is 1,
they can specified directly using parameters. Up to 20 addresses can be
used for signal selection. Selecting one signal uses three types of data,
that is, a signal type (X, G, F, or Y), address, and bit. These data types
correspond to parameters as listed below.
