Implementation Of PLC Arithmatic Instructions

Review Questions

1.    State different input parameters associated with “MUL” instruction.


2.    For evaluating arithmetic operation which instructions are generally available in PLC?


3.    What happens if arithmetic instructions are implemented using mix data types?


4.    In case of “SUB” instruction which action is performed if the rung condition input is true?


5.   In case of arithmetic instruction what is the status of enable out during pre-scan?
