1. AI: Ethernet Global Data

Each system wide PPS function block broadcasts a portion of its instance data onto the Ethernet global data highway. This data is used to interface with the function block from an HMI station in order to monitor and control a process system.

The Ethernet global data for the PPS AI block is as follows.
