When the SQI instruction is paired with the SQO instruction as illustrated:

A) the same control address, length value, and position value are used for each instruction.
B) the sequencer input instruction is indexed by the sequencer output instruction.
C) it allows input and output sequences to function in unison.
D) all of these.

SQI Instruction

An instruction in some programming languages or PLCs used to perform a sequential input operation or process.

SQO Instruction

A sequencer output instruction used in PLC programming to output a sequence of bits or words to control devices.

Sequencer Input

An input to a system that determines the sequence in which operations or events are to occur, often used in automated or programmed processes.
