Product Details

2MLL-C22B-CC Product Description

The Honeywell 2MLL-C22B-CC is a high-performance communication gateway module engineered for the MasterLogic PLC platform, purpose-built to bridge field-level devices and upper-level control systems across modern industrial networks. In smart factory environments where data continuity, protocol interoperability, and real-time visibility are non-negotiable, the 2MLL-C22B-CC delivers a robust, deterministic communication backbone that connects PLCs, remote I/O racks, HMI panels, SCADA servers, variable frequency drives, intelligent sensors, and edge computing nodes into a unified, transparent data architecture.

Designed for demanding process industries — including oil and gas, chemical processing, power generation, water treatment, and discrete manufacturing — this module supports seamless integration across multi-vendor automation environments. Whether deployed in a greenfield smart factory or retrofitted into an existing DCS/PLC hybrid infrastructure, the 2MLL-C22B-CC provides the communication reliability and protocol flexibility that modern industrial operations demand.

In a fully connected smart factory, the Honeywell 2MLL-C22B-CC sits at the heart of the data flow architecture, acting as the communication bridge between the MasterLogic PLC controller and the broader automation ecosystem. At the field level, intelligent sensors — including pressure transmitters, flow meters, and temperature probes — feed analog and digital signals into remote I/O modules such as the Honeywell HC-TDIL01 or compatible third-party I/O racks. These signals are aggregated and passed through the 2MLL-C22B-CC's backplane interface into the MasterLogic CPU for real-time processing.

On the network side, the module's Ethernet port connects directly to industrial managed switches — for example, a Hirschmann MACH104 or Cisco IE-3400 series industrial switch — enabling high-speed, deterministic data transmission across the plant LAN. From there, data flows upward to SCADA servers running platforms such as Honeywell Experion PKS, Wonderware System Platform, or Ignition by Inductive Automation, where operators gain real-time visibility into process variables, alarm states, and equipment health.

For facilities running mixed-protocol environments, the 2MLL-C22B-CC's CC-Link and PROFIBUS DP support enables direct communication with Mitsubishi MELSEC Q-series PLCs, Siemens S7-300/400 controllers, and ABB AC500 systems without requiring additional protocol converters. Variable frequency drives — such as the Honeywell SmartVFD or ABB ACS880 — can be integrated via Modbus RTU or PROFIBUS, allowing the SCADA layer to monitor motor speed, torque, fault codes, and energy consumption in real time.

At the edge, the 2MLL-C22B-CC can interface with edge computing gateways such as the Advantech ECU-1251 or Moxa ThingsPro Gateway, enabling local data preprocessing, OPC-UA publishing, and cloud forwarding to IIoT platforms. HMI panels — including Honeywell's own Experion Station or third-party units from Weintek and Proface — connect via Ethernet to display live process data, trend charts, and alarm histories sourced directly from the MasterLogic PLC through this communication module.

For remote I/O expansion, the module supports distributed rack architectures where Honeywell HC-RAIL or compatible remote I/O stations are deployed across the plant floor, all communicating back to the central MasterLogic controller through the 2MLL-C22B-CC's network backbone. This architecture eliminates the need for long home-run wiring, reduces installation costs, and improves signal integrity across large facilities.

Many industrial facilities operate with fragmented automation architectures — legacy PLCs running proprietary protocols, isolated SCADA islands, and field devices that cannot communicate with modern control systems. The Honeywell 2MLL-C22B-CC directly addresses these data gaps through its multi-protocol gateway capability.

Protocol Fragmentation: Sites running a mix of Modbus RTU legacy devices alongside newer CC-Link or PROFIBUS networks no longer require standalone protocol converters. The 2MLL-C22B-CC consolidates protocol translation within the MasterLogic backplane, reducing hardware complexity and potential failure points.

Data Silos: By providing a unified Ethernet interface to SCADA and MES systems, the module breaks down data silos between the OT and IT layers. Process data that was previously trapped in isolated PLC memory is now accessible to plant-wide analytics platforms, enabling production transparency and data-driven decision-making.

Remote Monitoring and Diagnostics: The 2MLL-C22B-CC supports remote diagnostic access via Ethernet, allowing maintenance engineers to interrogate PLC status, communication health, and module diagnostics from the control room or remotely via VPN — without requiring physical access to the panel. This capability is critical for reducing mean time to repair (MTTR) and minimizing unplanned downtime.

Alarm Tracking and Production Transparency: Integrated with SCADA alarm management systems, the module enables real-time alarm propagation from field devices through the PLC to operator workstations. Alarm timestamps, acknowledgment records, and event logs are preserved for post-incident analysis and regulatory compliance reporting.

System Scalability: As production lines expand, the 2MLL-C22B-CC's network architecture supports the addition of new remote I/O stations, drives, and field devices without requiring changes to the core PLC program or network topology — protecting the capital investment in the existing MasterLogic infrastructure.

Q1: What communication protocols does the Honeywell 2MLL-C22B-CC support, and is it compatible with third-party PLCs? The 2MLL-C22B-CC supports Modbus RTU, Modbus TCP/IP, PROFIBUS DP, CC-Link, and Ethernet/IP, making it compatible with a wide range of third-party controllers including Siemens S7 series, Mitsubishi MELSEC, and ABB AC500 platforms. Protocol compatibility should be verified against the specific firmware version and network configuration of the target system.

Q2: How does this module support remote diagnostics and what is the typical communication latency? The 2MLL-C22B-CC provides Ethernet-based remote diagnostic access, allowing engineers to monitor module health, communication status, and PLC I/O states via SCADA or dedicated diagnostic tools. Communication latency on the Ethernet interface is typically sub-10ms for cyclic data exchange under normal network load conditions, suitable for most process control and supervisory applications.

Q3: Can the 2MLL-C22B-CC be integrated into an existing SCADA or MES system without replacing the current PLC infrastructure? Yes. The module is designed for seamless integration into existing MasterLogic PLC racks and can be configured to communicate with SCADA platforms such as Honeywell Experion PKS, Wonderware, and Ignition via standard industrial protocols. No replacement of the existing PLC CPU or I/O modules is required — the 2MLL-C22B-CC adds network connectivity as a plug-in communication module.

Q4: What warranty and pre-shipment testing does NANKMOS provide for the Honeywell 2MLL-C22B-CC? All Honeywell 2MLL-C22B-CC units supplied by NANKMOS are covered by a 12-month warranty from the date of shipment. Each unit undergoes pre-shipment functional testing to verify communication interface integrity, backplane connectivity, and protocol response before dispatch. In-stock units are available for immediate shipment to minimize project lead times.
