What type of logic element is formed by arranging two XIC instructions in series in a PLC program?

Arranging two XIC (Examine if Closed) instructions in series in a PLC program creates an AND logic element. In a PLC, the XIC instruction checks if a specific condition is true (i.e., if the input is closed or has a high state). When two XIC instructions are connected in series, both conditions must be true for the overall output to be activated.

This series arrangement mirrors an AND logic operation, where the output is true only when all inputs are true. If either of the XIC instructions evaluates to false, the entire series path will not allow the output to be activated. Thus, this configuration achieves the intended AND logic functionality in the programmable controller's discrete control processes.
