The chart can display a maximum of 20 lines.
To display multiple items of data, set the sampling conditions and data size for the data to display to the
same settings. The data cannot be displayed if its sampling conditions or data size is different.
Device Display: Display the values of multiple, continuous devices as a single line chart. The data size
for the devices is 16 bits.
Updating and erasing the display is controlled by the lower 2 bits of the start address
value (control status) of the continuous devices.
The number of device values to display is specified by the value of start address + 1.
The device values from start address + 2 are displayed on the chart.
