What is the use of JMP (Jump instruction paired) instruction in PLC? Correct Answer Causing PLC to skip over rungs

JMP instruction of PLC:

  • The JMP instruction is used to cause the PLC to skip over rungs.
  • The Jump (JMP) instruction is paired with the Label (LBL) instruction by designating the same address number to each function.
  • When the jump rung is TRUE, it causes the ladder program to skip over rungs of the ladder program.

 

If the rung containing the JMP instruction is Then the Program
TRUE Skip from the rung with the JMP to the rung containing the designated LBL
FALSE Does not execute the JMP

A 5-stage pipelined processor has Instruction Fetch (IF), Instruction Decode (ID), Operand Fetch (OF), Perform Operation (PO) and Write Operand (WO) stages. The IF, ID, OF and WO stages take 1 clock cycle each for any instruction. The PO stage takes 1 clock cycle for ADD and SUB instructions, 3 clock cycles for MUL instruction, and 6 clock cycles for DIV instruction respectively. Operand forwarding is used in the pipeline. What is the number of clock cycles needed to execute the following sequence of instructions? Instruction Meaning of instruction I0 : MUL R2, R0, R1 R2← R0 * R1 I1 : DIV R5, R3, R4 R5 ← R3 / R4 I2 : ADD R2, R5, R2 R2 ← R5 + R2 I3 : SUB R5, R2, R6 R5 ← R2 – R6
Rita has the longest jump of 3 m 40 cm. Tanu is second. Her jump is 20 cm less than Rita's. Rihanna comes third. Her jump is only 5 cm less than Tanu's jump. By how many centimetres Rihana could not secure the first rank?
Which of the following assumptions is/are made in the analysis of hydraulic jump? 1. It is assumed that before and after jump formation the flow is essentially two-dimensional and that the pressure distribution is hydrostatic. 2. The length of the jump is small so that the losses due to friction on the channel floor are small and hence neglected. 3. The channel floor is horizontal or the slope is so gentle that the weight component of the water mass comprising the jump is very high.

Which of the following statements are true with regard to energy dissipation below a dam? (i) If the upper conjugate depth of a hydraulic jump is below the tailwater, little energy will be dissipated (ii) An upturned bucket will protect the dam from scour by moving material toward the dam. (iii) A secondary dam may increase tailwater height, thereby causing a hydraulic jump to form at the toe of the main dam. (v) A slopping apron above streambed level may be used to control the hydraulic jump so that it occurs on the apron. 
Consider the atomic jump. An atom next to a vacancy can make a jump provided it has enough thermal energy to overcome the activation energy barrier to migration. However, most of the time the adjacent site will not be vacant and the jump will not be possible. The probability that an adjacent site is vacant is given by_________. (X is the probability that any one site is vacant, z is the number of nearest neighbours)
