1. A compute/math instruction executes ...... each time the instruction is scanned as long as the rung-condition-in is true.
a) Once
b) Twice
c) Repeatedly

2) When the arithmatic operations are carried out in the PLC, if the data type for source and destination is not similar then,
a) loss of accuracy and rounding error occurs
b) Instruction takes more time to execute.
c) Both 1 and 2 above

3) ........... parameter stores the result of the math instruction
a) EnableOut
b) EnableIn
c) Dest

4) The data type of EnableOut is
