■
Set value
The set value (E2) is valid only when b0 of the set value pattern (SVPTN) is set to 0 (Used). To use the upper loop MV as the
set value (E2), specify the device (12) where the manipulated value (MV) of the upper loop is set.
If E2 is not used, specify a dummy device (SD820).
■
Execution cycle (
T)
Set the execution cycle (
T) in SD816 and SD817 in single-precision real number.
Processing details
This instruction performs two-position (on/off) control (2-contact ON/OFF) every control cycle.
The instruction also performs the following steps: SV setting, tracking, MV correction, and MV output processing.
The following is the processing block diagram of the S.ONF3 instruction. (The numbers (1) to (7) in the diagram indicate the
order of the processing.)
■
SV setting processing (1)
The following processing is performed depending on the control mode (MODE) setting.

Processing details

If the set value (E2) is specified, engineering value transformation processing (refer to the
following expression) is performed, and then "tracking processing (2)" is performed.
If the set value (E2) is not specified, "tracking processing (2)" is performed without performing
engineering value transformation processing.
MAN, AUT, CMV, CMB, CAB, LCM, LCA, LCC
"Tracking processing (2)" is performed.
