I/O information is referred to as what?

I/O information, which stands for Input/Output information, encompasses both the data that is fed into a system (inputs) and the data that is produced by it (outputs). Referring to I/O information simply as "data" captures the essence of what is being dealt with in a PLC system. In this context, "data" can include any kind of information processed or exchanged, whether it be the signals coming from sensors (inputs) or the control signals sent to actuators (outputs).

Saying "data" allows for a broader understanding of the concept, emphasizing the overall exchange of information between the PLC and the external devices. This term is inclusive of both inputs and outputs, providing a holistic view of how information moves in a system controlled by a PLC. By using the term "data," it becomes clear that we are referring to all kinds of relevant information that the PLC interacts with, thereby acknowledging the system’s comprehensive role in process control and automation.
