Blended PID (Block Model 013)
Section 6-17
The following table shows the units that are displayed. These units are fixed.
The following values are used in communications with the PLC.
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);
2: Realtime Trend Graph
Tag ITEMs Y1, Y2, and MV are displayed in graph format. The following table
shows the characteristics of each tag ITEM's line.
The following screen is a Tuning Screen for a Blended PID face plate built
using the Face Plate Auto-Builder for NS in a 640
