8. Ethernet/IP Communication
8.1. Overview
The Ethernet/IP interface is a CIP Modbus Translator Device (CIP Type 29) providing access to a virtual Modbus device (CIP Type
28h) defined according to CIP Volume 7 specification.
8.2. Usage Requirement
To fully use the functionality of the Ethernet/IP Modbus translator requires a compatible Network Master device that supports use
with a Modbus Translator Device (CIP Type 29) defined according to CIP Specification.
o Alternatively, the device may be support as a Generic CIP Bridge Device which supports cyclic communication only.
o Consult your PLC / Control Device vendor to determine compatibility.
When using the device to control the drive it is necessary to ensure that the amount of data and frequency of data exchange does
not exceed the amount of data which can be successfully exchanged on the Modbus sub-network within the permitted time.
o Recommended minimum RPI is 100ms.
o When Acyclic telegrams are exchanged, Cyclic telegrams should be paused.
Whilst the Optitools Studio PC software supports communication through the Ethernet network for device commissioning, it is not
recommended to use this continuously during operation of the drive as the additional communication load may exceed the limit
resulting in loss of Cyclic communication.
o In this case, connect the PC software to the drive serial port using the USB / RS485 adaptor.
Use port D1 or D2 of the external Ethernet adaptor.
Use port D1 or D2 of the Compact 2 Ethernet adaptor.
Use one of the available ports labelled “IOIOI”.
o Do not connect via Ethernet if data logging is required.
8.3. Operation
Cyclic control and monitoring of the drive is achieved by a Class 1 connection to the mapped Modbus PDI and PDO parameters.
This can be achieved using one of the following methods.
8.3.1. Configuration
The interface supports the following Ethernet/IP classes:
0x01 Identity
0x02 Message Router
0x06 Connection manager
0x45 Modbus Serial
0xF4 Port
0xF5 TCP/IP
0xF6 Ethernet Link
8.3.2. IP Address
The default IP address is 192.168.1.253, Subnet Mask 255.255.255.0
IP configuration can be changed using:
The TCP/IP Class 0xF5. Values will not be applied until an Identity Class 0x01 reset is executed
Via the internal webserver interface.
8.3.3. EDS File
EDS files are available from the Invertek website, www.invertekdrives.com.
Multiple EDS files are included to support a variety of Master network devices, e.g. Rockwell Automation, Codesys. The EDS files
contain the necessary path information to establish a connection as described below in further detail and may be used directly with
compatible master systems.
When creating the network configuration, add the CIP Modbus Translator device to the Ethernet/IP network and then add the
Optidrive to the Modbus Subnetwork below.
