Data is written to the write address of each tag ITEM using a Before Writing
Numeral/String macro, as follows:
$W2047=GETNUMVAL();
WRITECMEM([DEV_Q,K1/P/I/D/MH_LMT/ML_LMT/MV_IDX],$W2047,1);

Tag ITEMs Y1, Y2, and MV are displayed in graph format. The following table
shows the characteristics of each tag ITEM's line.
Tag ITEM Color
Y1 (016) Green
Y2 (029) Yellow
MV (089) Blue (Color
