Protocol Conversion Latencies & Network Performance

The module executes concurrent Client and Server operations across local or remote 1756 ControlLogix backplanes. The network interface supports up to 30 simultaneous Client connections and processes up to 100 independent Client commands, transmitting Modbus packets mapped straight into the 10,000-word internal database memory.

Integrating dual 10/100 Mbps Ethernet ports allows network segmentation or device-level architecture partitioning, isolating configuration tracking from active automation control. The internal execution engine handles protocol conversion latencies through optimized data block transfers, converting Modbus TCP/IP registers directly into native processor I/O data tables.

Frequently Asked Questions

Q: Does the MVI56E-MNETC module support Remove and Insert Under Power (RIUP) actions? A: Yes. The internal hardware components match standard 1756 chassis bus parameters, enabling hot-swap extraction and insertion while the slot is energized. However, disconnecting the module drops all active Modbus TCP/IP Client/Server sockets instantly.

Q: Can the dual Ethernet ports be configured for a redundant Ring topology? A: No. The two RJ45 ports provide independent IP routing structures designed for network segmentation (e.g., separating plant network access from local instrumentation loops). They do not serve as an integrated Device Level Ring (DLR) switch.

Q: How are configurations preserved if the module loses power? A: Configuration variables and command maps are stored in non-volatile flash memory inside the module. Backplane parameter setups and the Add-On Instruction (AOI) loaded in the RSLogix 5000 v16+ runtime automatically restore mapping tables during startup.

Field Installation Guidelines

Chassis Alignment: Slide the module firmly into any single available slot of a grounded 1756 ControlLogix chassis. Verify the mechanical locking tabs at the top and bottom snap fully into place to maintain physical backplane bus contact.
Shielded Network Cabling: Utilize Category 5e or higher shielded twisted-pair (STP) Ethernet cabling for all network lines. Ground the cable shields at the switch infrastructure to isolate the internal communications logic from industrial electromagnetic interference (EMI).
IP Address Allocation: Configure distinct static IP addresses for each utilized Ethernet port via the ProSoft Configuration Builder utility. Avoid assigning matching subnets to both ports to prevent local routing tables from conflicting.

What's clients say about us

Excellent Emergency Support!

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
