Question

Thank you for any help here with the following questions.

(1) The content of register R0 and a ladder logic program are given below. Determine which statement is true.

(2) What decimal number will be stored in register R50 after the toggle switch I1 is closed?

(3) The content of register R0 and a ladder logic program are given below. Which of the following statements is true?

The instruction on the right is a Compare instruction. R15 R14 R13 R12 R11 R10 R9 R8 R7 R6 R5 R4 R3 R2 R1 RO 0 0 0 0 0 0 0 0 0 001 0 111 ADD Toggle Switch RO Source 1 R20 Source 2 R50 -Destination

Explanation / Answer

1. The first problem is adder which adds data of R20 and R0 and stores the result at R50 as R20 has 13 as given in the first statement and the decimal value of content of R0 from the given data is 23 ( in binary 10111) so 13 amd 23 gets add up and the result 36 is stored at R50.

2. Here multiplication function is performed, whatever is stored in the R0 is multiplied with 2 and result is stored at R50.

As R0 has 13 ( binary 1101), it gets multiplied with 2 and the result 26 is stored at R50.
