To ensure interoperability and seamless access to device information, it is necessary to standardize on the form and basic contents of the information models for certain device classes independent of a specific communication protocol, thus enabling seamless instrumentation information flow throughout the enterprise.
This is the Process Automation Device Information Model (PA-DIM™).
Ethernet-APL is an enhanced physical layer for single-pair Ethernet (SPE) based on 10BASET1L. It will enable long cable lengths and explosion protection via intrinsic safety with communication and power over two wires.
Based on IEEE and IEC standards, Ethernet-APL supports any Ethernet-based automation protocol and will develop into a single, long-term stable technology for the entire process automation community.
