Class 0 Connection Details
General
Class 0 connections are only supported for safety connections. The CompactCom device will act as a
transparent bridge for safety connections, meaning that open and close requests for safety connections
and safety I/O data will be forwarded to the safety module. Class 0 connections use UDP transport.
Class 1 Connection Details
General
Class 1 connections are used to transfer I/O data, and can be established to instances in the Assembly
Object. Each Class 1 connection will establish two data transports; one consuming and one producing.
The heartbeat instances can be used for connections that shall only access inputs. Class 1 connections
use UDP transport. Null forward open is supported.
