What are analog module ports referred to as?

Analog module ports are commonly referred to as channels because each channel corresponds to an individual input or output point that can handle an analog signal. In the context of PLC systems, a channel often represents a designated path through which an analog signal can be processed, such as voltage or current levels. This terminology reflects the modular nature of PLC systems, where each channel can be independently monitored or controlled, allowing for precise manipulation of the analog signals entering or exiting the system.

While other terms like connections, lines, or nodes might be used in broader contexts within networking or electrical engineering, they do not specifically convey the functionality and role that "channels" indicate in the context of analog module ports in a PLC setup. "Channels" implies a structured approach to signal processing, maintaining clarity on the handling of multiples signals through the various pathways provided by the analog module.
