Overview of Timing Modes
The following diagram shows how an instruction determines the appropriate
timing mode.
The following instructions support the concept of Program/Operator control.
• Enhanced Select (ESEL)
• Totalizer (TOT)
• Enhanced PID (PIDE)
• Ramp/Soak (RMPS)
• Discrete 2-State Device (D2SD)
• Discrete 3-State Device (D3SD)
Program/Operator control lets you control these instructions simultaneously
from both your user program and from an operator interface device. When in
Program control, the instruction is controlled by the Program inputs to the
instruction; when in Operator control, the instruction is controlled by the
Operator inputs to the instruction.
Program or Operator control is determined by using these inputs.
