MVI56E-MNETCR | Prosoft Modbus Enhanced Communications Module

Product Overview

The ProSoft MVI56E-MNETCR is a high-integration Modbus TCP/IP Client/Server Communication Module with dual serial ports for the Allen-Bradley ControlLogix platform. It simultaneously supports Modbus TCP/IP, Modbus RTU, Modbus ASCII, and DF1 protocols, enabling "one-card" coverage of both Ethernet and serial devices. With 100 client commands + 20 server sessions and a 10,000-word data area, it meets high-density real-time control requirements while reducing wiring costs by up to 50%.

Installation Guide

1. Install in 1756 ControlLogix slot (local or remote rack, supports hot-swap)
2. Connect Ethernet cable to RJ45 port
3. Connect serial devices to P1/P2 ports
4. Configure protocols and command queues via PCB
5. Map data area to Studio 5000 tags using AOI
6. Enable SNTP or PTP time sync if required
7. Test all client/server connections

FAQ

Q: What does the "CR" suffix mean?
A: It indicates the module supports both Client and Server modes simultaneously with enhanced serial capabilities.

Q: Can I use this for 10,000+ data points?
A: Yes, the 10,000-word data area supports万点级 (10,000-point) real-time control with <10 ms refresh.

Q: Does it support remote configuration?
A: Yes, via CIPconnect through ControlNet or EtherNet/IP bridges.

Model Selection Tips

• MVI56E-MNETCR = All-in-one Modbus TCP + Serial module
• For Modbus TCP/IP only, use MVI56E-MNETC
• For extended temperature, add -XT suffix
• For pure serial Modbus, use MVI56E-MCM
• Verify ControlLogix backplane power budget (800 mA @ 5V)
