5.1 Product Specifications
The MVI56E-MNETR Modbus TCP/IP Client/Server Communication Module
allows Rockwell Automation
® ControlLogix ® processors to interface easily with
other Modbus TCP/IP compatible devices.
Compatible devices include Modicon PAC’s as well as a wide variety of
instruments and devices. This module uses a small I/O data area for data
transfer between the module and the ControlLogix processor, making it ideal for
ControlNet™ or Ethernet applications with the module in a remote rack. The
module exchanges up to 5000-words of data between the processor and the
Modbus TCP/IP network.
