OPC80

OPC80 is a designation that appears in a variety of technical contexts, typically used as a generic reference in education, glossaries, and vendor materials. There is no single, universally recognized definition for OPC80, so its meaning depends on the publication or domain in which it is used.

In hardware and automation contexts, OPC80 is often described as a compact programmable logic controller (PLC) family intended for small to mid-size automation tasks. Descriptions commonly cite a modular I/O approach, with digital inputs and outputs and optional analog channels, plus a network interface for industrial communication. Typical networking support might include Ethernet-based protocols and, in illustrative materials, compatibility with OPC UA or Modbus TCP. The emphasis in these references is on reliability, a small form factor, and straightforward integration with supervisory systems.

In software and protocol contexts, OPC80 can be used as a hypothetical version tag for an extended OPC interface, such as a reference to an “OPC 8.0” style protocol that would enable data access, eventing, and modern security features in industrial environments. It is frequently employed as an educational or illustrative label because OPC technologies are well-known in industry.

History and standardization: due to its broad and informal use, OPC80 does not have a single official specification. Accurate understanding depends on the source, vendor, or context in which the term is encountered.
