InvDeviceCoE402

This class is the basis for DS402-based inverters. In this context, the term CoE (CAN over EtherCAT) refers to the transmission of the CiA DS402 protocol via EtherCAT.

	Class is Abstract Since the class is defined as `ABSTRACT`, the class cannot be instantiated and must be implemented using inheritance.

Syntax:

FUNCTION_BLOCK ABSTRACT FB_InvDeviceCoE402 EXTENDS FB_InvDeviceEc
