Interface, Description, and Example
F_ISON Interface:
F_ISON(Cell position)
Description:
At the data on the cell specified by the argument, when the value
acquired at this time increases than the value acquired at previous
sampling, this function returns TRUE.
Otherwise, and the argument is not a numerical value, this function
returns FALSE.
In case that the sampling interval is set long, this function may not
return the correct value. Refer to "5.1.2 Setting the Monitor Data
Sampling Interval" for the relation between the sampling interval
and the monitoring data.
Example:
The cell F6 has the monitoring data of machine signal in the bit type,
and you want to get the rising state
(0 → 1) for the logging data output, set the following condition
formula to the "Condition".
= F_ISON(F6))
F_ISOFF Interface:
F_ISOFF(Cell position)
Description:
At the data on the cell specified by the argument, when the value
acquired at this time decreases than the value acquired at previous
sampling, this function returns TRUE.
Otherwise, and the argument is not a numerical value, this function
returns FALSE.
In case that the sampling interval is set long, this function may not
return the correct value. Refer to "5.1.2 Setting the Monitor Data
Sampling Interval" for the relation between the sampling interval
and the monitoring data.
Example:
The cell F6 has the monitoring data of machine signal in the bit type,
and you want to get the down state
(1 → 0) for the logging data output, set the following condition
formula to the "Condition".
= F_ISOFF(F6)
