B Implementation Details
B.1 SUP-Bit Definition
The supervised bit (SUP) indicates that the network participation is supervised by another net-
work device. In the case of EtherNet/IP, this means that the SUP-bit is set when one or more
CIP (Class 1 or Class 3) connections has been opened towards the module.
B.2 Anybus State Machine
The table below describes how the Anybus Statemachine relates to the EtherNet/IP network
Anybus State
WAIT_PROCESS
ERROR
PROCESS_ACTIVE
IDLE
EXCEPTION
B.3 Application Watchdog Timeout Handling
Upon detection of an application watchdog timeout, the module will cease network participation
and shift to state EXCEPTION. No other network specific actions are performed.
