Product Introduction
PROSOFT MVI56E-MNETCR is a Modbus TCP/IP Multi Client Enhanced Communication module for remote 1756 ControlLogix chassis, designed to connect a ControlLogix PAC to multiple Modbus TCP/IP server devices over Ethernet while using a small I/O data image to suit ControlNet and EtherNet/IP remote rack architectures. It appears to the controller as an I/O module with a user‑defined data map of up to 5,000 16‑bit registers and supports up to 30 Modbus clients on a single module.
The module adds Ethernet‑based configuration and diagnostics, CIPconnect pass‑through, an integrated web server, and backward compatibility with earlier MVI56‑MNETCR implementations, which lets you modernize existing Modbus TCP/IP links in remote racks without rewriting ladder logic while keeping network load and backplane image size within tight limits. Confirm controller firmware, network layout, and required client/server counts before standardizing on this variant instead of the standard MNET or MNETR modules.
