5.1 Product Specifications
The MVI56E Modbus TCP/IP Client/Server Communication Module allows
Rockwell Automation ControlLogix processors to interface easily with other
Modbus compatible devices.
Compatible devices include Modicon Programmable Automation Controllers
(PACs), as well as a wide variety of instruments and devices. A 5000-word
register space in the module exchanges data between the processor and the
Modbus TCP/IP network.
The MVI56E-MNET and MVI56E-MNETXT are functionally the same. The
MVI56E-MNET is designed for standard process applications. The MVI56E-
MNETXT is designed for the Logix-
XT™ control platform, allowing it to operate in
extreme environments and at higher operating temperatures. It has a conformal
coating to protect it from harsh or caustic conditions.
