Module overview

The EtherNET/IP Module is schematically equivalent to:

Fig. 219 EtherNet/IP Module

1. System LED (SYS)

2. Module Status LED (MS)

3. Network Status LED (NS)

4. Interface X1, standard RJ45

5. Interface X2, standard RJ45

LEDs Behavior

The subsequent table describes the meaning of the various LEDs found on the device.

LED	Color	State	Description
MS	Off	Off	No power
	Green	On	Device operational
	Green	Flashing	Standby
	Red	On	Major fault
	Red	Flashing	Minor fault
	Red/Green	Flashing	Self-test
NS	Off	Off	Not powered, no IP address
	Green	On	Connected
	Green	Flashing	No connections
	Red	On	Duplicate IP
	Red	Flashing	Connection timeout
	Red/Green	Flashing	Self-test
Ethernet LED	Off	Off	No link established
	Green	Blinking	Module is transmitting
	Green	Solid	A link is established

Module configuration

The module configuration can be seen under CONFIGURATION in Communication.

Fig. 220 EtherNet/IP Adapter configuration

Note

The IP settings are only displayed when at least one port of the module is connected otherwise N/A is displayed.

Tip

To change the IP address, use an external tool such as the Molex Industrial Communication Competence Center (ICCC) EtherNetIP Tool.

Network topology

When multiple EtherNet/IP devices are to be connected, three topologies can be implemented:

• Daisy chain and/or star topology:

  Modules are connected like a daisy chain where Module 1 is connected to Module 2, and so on. The last module does not require to be connected back to the master.

• Ring topology:

  Modules are connected such that they form a ring, Module 1 is connected to Module 2, and so on. The last module is connected back to the EtherNet/IP Scanner, thus forming a ring.

• Tree topology:

  Modules are connected such that they form a tree. A Module is the root node to which multiple Modules (branches) can be connected. The last modules (at the end of the branches) do not require to be connected back to the master.

Please, review your requirements to choose which topology best fits your needs.

Assemblies

EtherNet/IP allows exchanging cyclic real-time data using assemblies. There are two types of assemblies corresponding to the two directions: consuming and producing assemblies.

All the necessary commands, parameters and output data are implemented in assemblies so that you can easily and fully integrate your EYE+ into your application. Assemblies are mostly mirroring the TCP Protocol interface while providing a specific and convenient interface to use. We highly recommend you read the TCP programming guide before integrating EYE+ using the EtherNet/IP Module.
