Both normally open and normally closed pushbuttons can be represented by the XIC or XIO instruction.
Normally Open
Describes a switch or relay contact that is open (disconnected) in its resting state and closes (connects) when activated.
XIC Instruction
A "Examine if Closed" instruction in PLC programming, used to check if a specific condition or input is true.
XIO Instruction
"Examine if Open" instruction in PLC programming, used to check if a Boolean input condition is false before executing the subsequent logic.

Final Answer :
True
Explanation :
Both normally open (NO) and normally closed (NC) pushbuttons can be represented using the XIO (eXamine If Open) and XIC (eXamine If Closed) instructions in ladder logic. The XIC instruction is used to examine if the input is closed or energized, while the XIO instruction is used to examine if the input is open or de-energized. Therefore, both types of pushbuttons can be represented using either XIC or XIO instructions.
