6.8. Drive parameter access
6.8.1. Overview
The OPT-2-ETHEG-IN is a Modbus translator device. This means that all data accessible from the drives Modbus RTU interface may
also be accessed via the Ethernet/IP interface.
For details of the relevant Modbus registers available for each drive, refer to the drive documentation.
6.8.2. Supported Ethernet/IP Classes
The OPT-2-ETHEG-IN supports the following Ethernet/IP classes to allow communication with a connected Drive:
 0x01 Identity
 0x02 Message Router
 0x04 Assembly
 0x06 Connection manager
 0x0F Parameter
 0x44 Modbus.
Drive parameters may be accessed using unconnected or Class 2/3 connection via following methods:
Status LED Function
0x0F Parameter
0x0E Get_Attribute_Single
Individual parameter Read/Write
Instance 1 = holding register 0
0x10 Set_Attribute_Single
0x44 Modbus Object
0x4E Read_Holding_Registers
Multiple parameter Read/Write
Instance 1 = holding register 0
0x50 Write_Holding_Registers
0x04 Assembly Object
0x18 Get_Member
0x19 Set_Member
NOTE
All Optidrives support the following Modbus RTU Commands:
 0x03 Read Multiple Holding Registers.
 0x06 Write Single Holding Register.
Sequential blocks of available Modbus Registers may be read either by using multiple 0x0E Get_Attribute_Single commands or by
using a single 0x4E Read_Holding_Registers to read multiple register values in a single command.
In order to write parameter values to the drive, each individual parameter must be written in a singularly, either using 0x10 Set_
Attribute_Single or 0x50 Write_Holding_Registers. It is not possible to write multiple parameters in a single command.
