Answer as soon as impossible .. before 30 mins please

1. State which one instruction (OSR, LIM, FFU,LPU, S00, TND, NEQ. SBR, RET) is best suited to the application shown Make a subroutine stop running and return control to the routine that called b)Store a group of 8 binary bits by moving bits in one at a timae )Determine if a number is outside of a specitied range d.) Remove the most recenty added word of data from a register Cause a pre-defined sequence of lights to turn on in a repeated patterm f) Determine it two numbers are different from one another. Which of the following statements are true? (Circle the letter of each true statement) a.) A user may force I/O in a PLC program to troubleshoot hardware b) An MEQ instruction is used to determine if a number is more than or equal to another 2. number. c) The SQC instruction can be used in a SLC500 to determine if a set of inputs match a given sequence d.) After the last step in an SQ0 instruction is completed there is a return to the 0 step e.) In a Controllogix system, a single SQO instruction can be used to control 32 discrete outputs f) Every JMP instruction must have one and only one SBR instruction associated with it For a SLC500 processors, how many 16-bit words of memory would be required for each of the following situations? 3. a) The destination of an FAL instruction with an address of N7 6 and a length of 8. b ) The destination of an FAL instruction with an address of #N7 2 and a length of 8. C) The file of a BSR instruction with an address of#831 and a length of 32. d) The file of an SQO instruction with an address of #83:5 and a length of 6. 4. An MVM instrution in a L00 has the following values before it is energized Mask COF3h Destination 0010 1100 1110 0010 What is the value at the destination after the instruction is energized?

Answer 1

Lim: Test whether one value is within the unit range of two other values. NEQ: Test whether one value is not equal to a second value. BSR: BSR command is an output instruction that loads data into a bit array one bit at a time SQO: sequence output: controls sequential machine operation by transferring 16-bit (1 word). FFU: It is used to unload words from FIFO stack, in the same order as the words entered. First word entered is the first word out. LFU: used to unload words from LIFD stack, in the opposite order were entered. TND: Temporary End: stops the processor from scanning the rest of the program file. SBR: SBR (subroutine) instruction must be the first instruction on the first rung in the program files that contain sub routines. RET: RET moves the end of sub-routine execution (or) end of sub-routine file. It resumes execution of program where JSR command instruction was placed.
