Product Specifications
The Modbus TCP/IP Client/Server Enhanced Communication Module with
Reduced Data Block allows Rockwell Automation
®
ControlLogix
®
processors to
interface easily with Modbus TCP/IP-compatible devices, such as Modicon
Programmable Automation Controllers (PACs) and a wide variety of Modbus
TCP/IP-compatible instruments and devices.
The MVI56E-MNETR uses a reduced Input/Output (I/O) data image block size for
transferring data between itself and a ControlLogix processor. This makes it ideal
for remote rack applications using ControlNet™ or EtherNet/IP™ process
networks. The module also works well for applications that require redundant
ControlLogix processors.
MVI56E-MNETR enhancements include local and remote configuration and
diagnostics through the module’s Ethernet port, CIPconnect
®
technology for
bridging though Rockwell Automation ControlNet and EtherNet/IP networks, and
an on-board web server for access to module documentation and sample
program files.
