What is XIO and XIC in PLC?

The XIO, also known as Examine If Open, instruction perform the function opposite to the XIC (Examine if Closed). It’s a fundamental instruction for working with Programmable Logic Controllers (PLCs).

What is XIC instruction in PLC?

The XIC, also known as Examine If Closed, instruction is one of the fundamental instructions used in ladder logic programming for Programmable Logic Controllers (PLCs). This instruction is always found on the left side of a ladder rung and will verify if the specified bit is in a logic HIGH state.

What are the basic instructions used in the PLC programming?

Types of Instructions in PLC Programming

• Relay Logic Instructions. Examine if Closed (XIC)
• Input Transition Sensing Instructions. Positive Transition Sense (PTS)
• Output Instructions. Output Energize (OTE)

What is an xic symbol?

The symbol for the Examine If Closed (XIC) instruction is: ——–] [——– The XIC instruction looks and operates like a normally open relay contact. There is a memory bit associated with each XIC instruction that is linked to the status of an input device or internal condition.

When the XIC instruction is associated with a physical input?

When the XIO instruction is associated with a physical input, the instruction will be set to 1 when there is no input voltage applied to the terminal. Both normally open and normally closed pushbuttons can be represented by the XIC or XIO instruction.

When using an XIC instruction the reference address could be an?

When using an XIC instruction, the reference address could be: A bit from an input device, an output device or an internal relay. A normally open limit switch is wired to an input module and programmed using XIO instruction.

When using an XIC instruction the reference address could be group of answer choices?

When using an XIC instruction the reference address could be quizlet?

The address I:1/3 identifies an input module residing in slot___ of the PLC chassis. When using an XIC instruction, the reference address could be: a bit from an input device, a bit from an output device, and a bit from an internal relay.
