Question

The ____ instructions always interprets a 1 status as true and a 0 status as false. XIC XIO contact all of these In order to energize the starter coil: pressure switch, the temperature switch and the manual pushbutton must be closed. the pressure switch, or the temperature switch, or the manual pushbutton must be closed. the pressure switch and the temperature switch or the manual pushbutton must be closed. All of the above. Which of the following is not an advantage that PLCs offer over the conventional relay-type of control system? Smaller size Less expensive Higher current capacity More reliable. At the start of the PLC scan the: status of all inputs are read status of all outputs are updated program is executed diagnostics and communications tasks are executed. The decimal number 28 would be written in binary as: 11100 00111 10110 01011. The basic rule for an XOR function is: if one or the other, but not both, inputs are 1, the output is 1. if one or more inputs are 1, the output is 1. if one or more inputs are 1, the output is 0. if one or more inputs are 0, the output is 1.

Explanation / Answer

Question 9 answer XIC

XIC Stands for "examine if closed"

Here if input value is 1 the instruction is true which allows the instructions to the right to be executed.

If the input value is 0 the instruction is false which disables instructions to the right.

1 -True

0 - False

On the other hand XIO "examine if open" is opposite 1 - FALSE 0 is TRUE

Here if input value is 0, the instruction is true which allows the instructions to the right to be executed.

If the input value is 1, the instruction is false which disables instructions to the right.
