5.1 Product Specifications

The MVI56E Modbus TCP/IP Client Enhanced Communication Module -

Client/Server allows Rockwell Automation

ControlLogix

Programmable

Automation Controllers (PACs) to interface easily with Modicon Programmable

Automation Controller (PACs) , as well as multiple Modbus TCP/IP server-

compatible instruments and devices. The multi-Client module improves

performance when controlling multiple servers on a Modbus TCP/IP network, by

supporting up to 30 Clients. It also supports up to 20 server connections (10

MNET, 10 MBAP).

MVI56E enhancements include configuration and management through the

module’s Ethernet port, and CIPconnect

technology for bridging though

ControlNet™ and EtherNet/IP™ networks.
