EATON
www.eaton.com
Operation
Cyclic data
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 as follows.
Method 1: Class 1 connection to Drive Assembly object
Drive IO control can be achieved via Class1 connections to the
Assembly Object (0x04).
The controller must implement the forward open request to the
DX-NET-ETHERNET2-2 Port 3, address 1.
For Drive specific allocation, refer to Drive Manual and/or
EtherNet/IP EDS file.
For Drive specific read/write limitations, refer to Drive Manual
and/or EtherNet/IP EDS file.
The following connection setting will establish a Class 1 connection
to transfer Drive PDI/PDO Modbus registers.

Method 2: Class 1 connection via DX-NET-ETHERNET2-2
‘Forward Open Assembly’ object
The DX-NET-ETHERNET2-2 provides the Vendor Class ‘Forward
Open Assembly (0x0300)’ which negates the need for the control
to provide the forward open mapping.
For Drive specific allocation, refer to Drive Manual and/or
EtherNet/IP EDS file.
For Drive specific read/write limitations, refer to Drive Manual
and/or EtherNet/IP EDS file.
The following connection setting will establish a Class 1 connection
to transfer Drive PDI/PDO Modbus registers.
