Curve Sampling Status Flag When the HMI samples a trend graph or X-Y chart, the curve sampling status flag (bits
0 to 3) is turned ON. After the sampling operation is completed, the curve sampling
status flag is turned OFF. Curve Sampling Flag 1 of control block corresponds to Curve
Sampling Status Flag 1 of status block, Curve Sampling Flag 2 of control block
corresponds to Curve Sampling Status Flag 2 of status block and vise versa.
Curve Clear Status Flag When the HMI clears trend graph or X-Y chart, the curve clear status flag (bits 8 to 11)
is turned ON. After the clear operation is completed, the curve clear status flag is
turned OFF. Curve Clear Flag 1 of control block corresponds to Curve Clear Status Flag
1 of status block, Curve Clear Flag 2 of control block corresponds to Curve Clear
