OutputCoE408

This class can be used for a DS408 based hydraulic valve. In this context, the term CoE (CAN over EtherCAT) refers to the transmission of the CiA DS408 protocol via EtherCAT.

Syntax:

FUNCTION_BLOCK FB_OutputCoE408 EXTENDS FB_OutputBase

I/O variables

Name	Type	Direction	Description
