Batch Flowrate Capture (Block Model 014) Section 6-18
The following values are used in communications with the PLC.
The overrun, pre-batch, and flowrate limitation settings are set as follows:
• Storage format: UDINT
• Characters displayed: 5 integer digits and 1 tenths digit
• Units and scaling: Set to ×0.001 during conversion.
Data is written to the write address of each tag ITEM using a Before Writing
Numeral/String macro, as follows:
• Macro for the overrun, pre-batch, and flowrate limitation settings:
$W2047=BCD(GETNUMVAL()/1000);
WRITECMEM([B0/BP/B1],$W2047,1);
RETURN(1);
• Macro for the MV index position:
$W2047=GETNUMVAL();
WRITECMEM([MV_IDX],$W2047,1);
RETURN(1);

Tag ITEMs Y1 and MV are displayed in graph format. The following table
shows the characteristics of each tag ITEM's line.
