■
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 ratio calculation when the specified control cycle is reached.
At this time, the instruction also performs the following steps: control mode (MODE) determination, engineering value
transformation, tracking, and variation rate limiter.
SPR: Set value, R
n
: Current ratio value, DR: Variation rate limit value, Cy: Control cycle
The following is the processing block diagram of the S.R instruction. (The numbers (1) to (6) in the diagram indicate the order
of the processing.)
