Ethernet/IP (EIP)
The iPAK2v2
control’s EtherNet/IP has the ability to exchange control setting parameters,
control Inputs data and
Outputs (Status) data with a PLC, HMI or computer. Both Implicit messaging and Explicit messaging are offered by the
iPAK2v2 control.
8.3.1
Implicit Messaging
The iPAK2v2 control uses Implicit messaging for Inputs/outputs (control status) data exchanging with other EtherNet/IP
devices.
To communicate with the iPAK2v2 control through Implicit message, the controlling device (usually a PLC) must work as
an Originator to initiate a class 1 connection. The following
shows the required parameters to setup the
Originator.

Input Data Structure
The iPAK2v2 control accepts 4 bytes of input information from a PLC or any EtherNet/IP devices through Originator-
>Target (O->T) message. This should be interpreted as 2 16-bit words input data, see
