■Input data 2
Processing details
This instruction outputs data in the specified mode (automatic or manual mode).
• In automatic mode, the instruction outputs the value selected by the selection signal (e1) from the input values 1 (E1) and 2
(E2).
• In manual mode, it outputs the manipulated value (MV).
The following is the processing block diagram of the S.SEL instruction. (The numbers (1) to (7) in the diagram indicate the
order of the processing.)
■Engineering value transformation (1)
The instruction performs engineering value transformation using the following expression.
■Input value 1 (E1), 2 (E2) selection processing (2)
Specify the input value selection (e1) of the set value pattern (SVPTN) to specify which input value is to be used, 1 (E1) or 2
(E2).
• Input value selection (e1) = 0: Input value 1 (E1) is used. Selected value (PV) = process value 1 (PV1)
• Input value selection (e1) = 1: Input value 2 (E2) is used. Selected value (PV) = process value 2 (PV2)
Selected No. (SLNO): The bit corresponding to the input value E1 or E2 is set to 1.
