Commissioning for EtherNet/IP

Configuration
Implicit and Explicit Messaging
The Ethernet IO modules support implicit and explicit messaging for EtherNet/IP communica-
tion. IO process data is transmitted on a cyclical basis via assembly objects and an existing
connection using implicit messaging.
Low-priority data, non-time-critical data, configuration and diagnostic data can be exchanged
via non-cyclical messages using explicit messaging.
Connections and Assembly Object
The Ethernet IO modules support connection types Exclusive Owner, Input Only and Listen
Only for exchanging IO process data and communication via implicit messaging.
•
Exclusive owner
This connection is bidirectional: the controller sends data to the module and the module
sends data to the controller. This type of connection is known as exclusive owner because
it connects
one
module to the controller in each case.
•
Input only
With this type of connection, only the module sends data to the controller. The module
sends a heartbeat, possibly at reduced intervals. This enables the controller to detect
interruptions to the connection.
•
Listen only
This connection corresponds to the input only connection but can only be established if
an exclusive owner or input only connection also exists between another module and the
controller.
An
“
exclusive owner
”
connection is only available for modules with output functionality (variants
16DIO and 8DI8DO). By selecting the corresponding instance ID for the assembly object, you
determine whether the module adds diagnostic data to the standard process data.
The 16DIO-variant Ethernet modules are universally applicable and provide a variety of profiles
for basic configuration. Using these, you can preconfigure a 16DIO module as a 16DI, 16DO or
8DI/8DO module, among other things, and replace a module where required, for example.
Each I/O channel can be used as an input or output for the 16DI/DO profile. If an I/O channel is
used as an input, the PLC programmer should not set the corresponding output bit.
By using the preconfigured alternate profiles, the risk of incorrect configuration is reduced
through the use of profiles 16DI, 16DO or 8DI/8DO. In these profiles, the I/O channels are con-
figured as "input" or "output."
Ethernet IO modules of type ICE1-8DI8DO-G60L-C1-V1D ICE1-16DIO-G60L-C1-V1D have
the DCU function. For these, the process data is extended in both directions by 18 additional
bytes.

The device performs a reset to factory settings. The network parame-
ters are also reset to the default values. Communication is not possi-
ble in this operating mode.
