Product Introduction
The ProSoft Technology MVI56E-MNETC is an advanced, high-performance communication module engineered specifically for the Rockwell Automation ControlLogix (1756) programmable automation controller (PAC) architecture. Functioning as an enhanced Modbus TCP/IP multi-client and multi-server gateway, it allows ControlLogix processors to interface smoothly with third-party Modbus TCP/IP-compliant instruments, drives, PLCs, SCADA packages, and distributed control systems (DCS).
Unlike basic single-client versions, the MNETC variant supports up to 30 Modbus TCP/IP Clients and 20 Servers simultaneously, functioning as a high-capacity data concentrator that optimizes polling performance across complex network topologies.

Compliance & Standards Alignment
- Manufactured in accordance with global safety guidelines, CE, UL/cUL, ATEX, and IECEx requirements for industrial control hardware and hazardous location deployment.
- Designed with high electromagnetic immunity to protect internal logic and network packets from electrical noise generated by heavy industrial switchgear and variable frequency drives.
Technical Note: The MVI56E-MNETC integrates directly into Studio 5000 / RSLogix 5000 using supplied Add-On Instructions (AOIs) and sample ladder files, drastically cutting down engineering time by eliminating complex custom serial or socket programming blocks.
Storage & Asset Preservation Guidelines
- Store the module inside its original manufacturer antistatic ESD shielding bag to protect sensitive internal microprocessors and network transceiver chips from electrostatic discharge.
- Keep warehouse storage environments clean, temperature-controlled, and strictly below 60% relative humidity.
- Avoid mechanical shocks, drops, or placing heavy weights on the module box to prevent bending the backplane connector pins.
Physical Installation Prerequisites
- Ensure that the ControlLogix chassis power supply is completely turned off and locked out (LOTO) prior to module insertion or removal.
- Slide the module gently along the chassis card guides into any available slot, ensuring correct alignment with the backplane bus before pressing firmly to seat the unit.
- Secure the top and bottom module retaining screws to guarantee mechanical stability and reliable electrical ground continuity.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this ProSoft communication module?
A: Industrial communication interface cards, network adapters, and data transmission hardware typically classify under HS code 8517.62 (Machines for reception, conversion and transmission or regeneration of data) or 8538.90. Confirm final parameters with your customs broker.
Q: Can the MVI56E-MNETC be used in remote ControlLogix racks?
A: Yes, the module can operate in local or remote racks via EtherNet/IP or ControlNet bridging (using CIPconnect technology), though data block structures should be reviewed if network bandwidth is heavily constrained.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, inventory conditions, and software release tiers; contact our technical sales desk for a formal, time-sensitive quotation.
