EtherNet/IP-Modbus Gateway Overview
- Via Read-from-Tag/File and Write-to-File/Tag configurations
The most extensive Modbus functionality in the industry:
• Up to 96 Modbus/TCP connections
• Support up to eight unique Modbus TCP socket port numbers. (i.e. 502, 503, 505, etc.)
• Multiple Modbus/RTU and/or Modbus/ASCII over Ethernet TCP connections
• Local serial Modbus/RTU and Modbus/ASCII slave devices
• Maximum sized Modbus messages
• Serial Modbus/RTU and Modbus/ASCII masters
• Shared Memory that can be configured to provide communication interfaces between a vast array of
Modbus slaves, Modbus masters and EtherNet/IP controllers.
• Modbus Alias functionality
• Remote Modbus device connectivity
• Modbus slave to Modbus slave communication
• Private Modbus serial bus connectivity – A serial port connected to a serial master and one or more serial
slave devices
A Data Mapping process that provides:
• EtherNet/IP Tag/File to Modbus connectivity - to either Modbus device(s) or Shared memory
• Modbus to EtherNet/IP Tag/File connectivity - from either Modbus device(s) or Shared memory
• Modbus to Modbus connectivity
- Can read from multiple Modbus devices into Shared Memory.
- Can write from Shared memory to multiple Modbus devices.
- Can read directly from one Modbus slave device to another Modbus slave device anywhere on the
Modbus network. These devices can be of any supported type, local or remote.
- Can convert from Modbus register type to another automatically.
• A Data Mapping verification web page that checks for possible Modbus write conflicts, incorrect
configuration and write violations.
• A Shared Memory map web page that displays the Shared Memory read and write memory blocks as
defined utilized by the Data Mapping.
