4.5.3 ETHERNET/IP INTERFACE
EtherNet/IP (Ethernet Industrial Protocol) is a communications protocol
developed by Rockwell Automation, managed by the Open DeviceNet
Vendors Association (ODVA) and designed for use in process control and
other industrial automation applications.
ASD power supplies internally use an Ethernet/IP device called NET485-
EIP-MB. This device converts Ethernet/IP protocol to Modbus protocol,
which is described in previous sections of this manual.
The interface expects a BOOTP server to get the IP address at power up,
but a fixed IP address can be configured remotely by using a software
capable of sending Ethernet/IP explicit packets, such as EIP Scan Test
Tool, from Pyramid Solutions.
For real time control of the power supply, the Ethernet/IP interface has an
input assembly object (class 0x04, instance 0x65) and an output
assembly object (class 0x04, instance 0x66), with similar functionality to
the Mosbus registers.
I NPUT
The input (Target to Originator) assembly object has the following read
registers:

Input assembly status word (16bit), not used.
 Status (16bit)
 Fault bits (32bit)
 Voltage monitor (32bit)
 Current monitor (32bit)
 Power/Process monitor (32bit)

Existing modules (16bit)
 Active modules (16bit)
Total of 24 bytes.
O UTPUT
The output (Originator to Target) assembly object has the first 4 write
registers:
 Output assembly configuration word (16bit), includes the Run/Idle bit.

Command (16bit)
 Voltage setpoint (32bit)
 Current setpoint (32bit)
 Power/Process setpoint (32bit)
Total of 16bytes.
