Introduction

EtherNet/IP (EtherNet Industrial Protocol) is a real-time Ethernet which is mainly used in

automation technology.

The EtherNet/IP bus monitor ibaBM-ENetIP is a device for acquiring the cyclical data

exchange between EtherNet/IP scanner (master) and adapters (slaves). The device can

be integrated into an existing EtherNet/IP network with one or more EtherNet/IP scan

ners (master).

The ibaBM-ENetIP bus monitor can be operated in an EtherNet/IP network without inter

ferences using the TAP interface (Ethernet). The device works as sniffer, i.e. it listens to

the cyclic data exchange of the IO data (implicit messaging) between EtherNet/IP scan

ner (master) and adapters (slaves).

The entire communication via the TAP interface is being mirrored to a monitor port and

can be recorded using an external network analysis tool.

On the optical-fiber side, ibaBM-ENetIP works with the ibaNet protocol 32Mbit Flex. With

this protocol, measuring and configuration data are transferred via a bidirectional fiber

optic connection.
