Outline Section 1-1
Hex and 0000 to 7D00 Hex are converted to −320.00 to −0.01 and 0.00 to
+320.00%, respectively, before they are processed.
2. Any data range in CPU Unit I/O memory corresponding to 0 to 100% on
the Loop Controller can be specified. (The data range is dependent on the
specified input range and output range in the user link table.)
CX-Process Tool scales these percentage values to engineering units val-
ues, and SCADA software or a PT monitors and sets the values in engi-
neering units. (For details, see 3-1 Configuration of Function Blocks.)
3. The Loop Controller does not process analog data in engineering units
(scaled values). (All analog data is processed in percentage values.) To
monitor/and set analog data in engineering units, the analog data must be
scaled on CX-Process Tool and then monitored and set on SCADA soft-
ware or a PT.
