4.1.2 Encoder Object

The main functions of a PROFINET Encoder are defined by the Encoder Object (EO). The general architecture of an Encoder Object is shown in Figure 2.

Figure 2 – General Encoder Object architecture ([ENCP] chapter 5.2.3)

As defined in [ENCP], the EO shall have the following minimum functionality:

Parameters

Measuring task

IO Data (setpoint values, actual values)

Support for diagnosis mechanism

Clock synchronous operation

Fault buffer

The OPC UA for PROFINET Encoder Information Model provides access to parameters, IO Data, diagnosis, and fault buffer information.
