3.2 OPC UA for PROFINET Drives Terms from Profile Drive Technology – Encoder Profile [ PI 3162 ENCP ]

Excerpt from [PI 3162 ENCP], chapter 4.1.

3.2.1 Output Data

Data, which a device cyclically receives from the controller and which it outputs to the device application or the peripherals.

3.2.2 Input Data

Data, which a device cyclically sends to the controller.

3.2.3 IO Data

For Devices, all Input and Output Data (cyclic transmission).

3.2.4 DO IO Data

For a Drive Object (PROFIdrive), all Input and Output Data (cyclic transmission).

3.2.5 Process Data

For Devices, all data related to the control process (e.g. gain factor, state variables, …). The Process Data typically is mapped on parameters (access is with acyclic transmission).
