What Are the Three Steps of a Sequential Scan Cycle

Question

Examlex · Accepted Answer

The Answer is The first step is to check all the inputs.For the binary inputs,if the proper amount of voltage is present,it will put a 1 in box in the memory that correlates to that terminals address.If the input is analog,it will put a group of 1s and 0s into a word's worth boxes with the corresponding address,based on the amount of voltage or current present at the terminal.The next step in the sequential scan sequence is to read the program from top to bottom,left to right.The third part of the scan cycle is to connect or disconnect output connections.If the output is digital in nature or the on/off type,a 1 in the data box for that address instructs the output module to make a connection between the designated terminal screw and the common connection.If the output is analog in nature,a specific voltage or amperage is sent to the terminal screw that matches the data in the word of data for that address.
