Curve Sampling Flag Bits 0 to 3 (flags 1 to 4) control the curve (Trend Graph, X-Y Chart, X-Y distribution or
Curve Input) sampling. When this flag is turned ON, HMI will read continuous data
from the set PLC address to sample once, changes the data to the graph and shows it
on HMI screen (For more details on the settings of curve element, please refer to
section 3.8.10). To control the curve sampling flag again, this flag must be turned OFF
and then ON again.
Each curve element has to be assigned to a sampling flag where the sample flag is
setup in the detail property of the element. To enable the curve element, set the
corresponding bit in this register. For example (refer to Table 3-4-1 and Fig. 3-4-5), if
D2 or $17.0 is set to 1, the curves of figure 1 and 2 will be activated and show on the
screen and the curves of figure 3 and 4 will not. When D2=1, it indicates that Bit 0 of
D2 is 0 (0000 0000 0000 0001).
