Execution Times for the STL Instructions (in µs), continued
Table F-4
Instruction
OW > = Execution time when comparison is true
Execution time when comparison is false
PID Basic execution time
Adder to recalculate (K
prior to the PID calculation. Recalculation occurs if
the value of K
c
previous execution of this instruction, or on a
transition to auto control.
PLS Basic execution time
R Total = Operand time + (LM) (Length)
Counter execution time
Timer execution time
Other operand execution time
Counter length multiplier (LM)
Timer length multiplier (LM)
Other operand length multiplier (LM)
If the length is stored in a variable instead of being a
constant, increase the basic execution time by
adding:
RCV Basic execution time
RET Basic execution time
RETI Basic execution time
RI Total = Basic time + (LM) (Length)
Basic execution time
Length multiplier (LM)
If the length is stored in a variable instead of being a
constant, increase the basic execution time by
adding:
RLB Total = Basic time + (LM) (Length)
Basic execution time
Length multiplier (LM)
RLD Total = Basic time + (LM) (Length)
Basic execution time
Length multiplier (LM)
RLW Total = Basic time + (LM) (Length)
Basic execution time
Length multiplier (LM)
RRB Total = Basic time + (LM) (Length)
Basic execution time
Length multiplier (LM)
RRD Total = Basic time + (LM) (Length)
Basic execution time
Length multiplier (LM)
