7 Ethernet Industrial Protocol (EtherNet/IP™)
7.1 Description
The EtherNet Industrial Protocol (EtherNet/IP™) is an open communication standard
based on the classic Ethernet protocols TCP/IP and UDP/IP.
EtherNet/IP™ was defined by the Open DeviceNet Vendor Association (ODVA) and
ControlNet International (CI).
With EtherNet/IP™, Ethernet technology is expanded to include the CIP (Common In-
dustrial Protocol) application protocol. CIP is known in the field of automation engin-
eering because it is also used for DeviceNet™ and ControlNet as an application pro-
tocol.
7.2 Process data exchange
The device can exchange the following process data words with an EtherNet/IP™
master (PLC), depending on its use:
• MOVIPRO
®
SDC up to 8 process data words
• MOVIPRO
®
ADC up to 120process data words
The process data length sets the EtherNet/IP™ master on opening the connection.
In addition to a controlling "Exclusive Owner Connection", up to two additional "Listen
Only Connections" are possible. This means the actual values of the drive can also be
read out by stand-by controllers or visualization devices.
If there is already a controlling connection via Modbus/TCP, you cannot activate an
"Exclusive Owner Connection" via EtherNet/IP™ before a power-on reset.
