Product Overview

The IC200CMM020 functions as a dedicated Modbus Master interface for the VersaMax I/O system. This module enables a VersaMax station to orchestrate communications across an RS-485 network, controlling up to 247 Modbus RTU slave devices such as drives, sensors, and power meters. Designed for seamless integration with Genius and PROFINET Network Interface Units (NIUs), it bridges the gap between decentralized I/O stations and third-party serial devices. We provide this unit as 100% Brand New and Original in Factory Packing, ensuring stable data throughput and industrial-grade reliability for your communication backbone.

Engineering Advantages

Expanded Network Reach: The IC200CMM020 transforms a standard I/O station into a powerful communication hub. By supporting up to 247 slaves, it allows engineers to consolidate data from a vast array of Modbus-compliant peripherals into a single VersaMax node.
Flexible Duplex Operations: The module supports both Half and Full Duplex RS-485 wiring. This flexibility accommodates various field wiring architectures and legacy device requirements, ensuring reliable data exchange regardless of the existing cable infrastructure.
High-Density Integration: You can install up to two IC200CMM020 modules per Genius or PROFINET NIU station. This dual-module capability effectively doubles your serial communication capacity without requiring additional PLC CPUs or specialized gateways.
Noise-Resistant RS-485 Physical Layer: Utilizing the RS-485 standard, this module excels in electrically noisy industrial environments. It maintains signal integrity over long distances, making it ideal for distributed systems spanning large factory floors.
Streamlined Diagnostics: Integrated LED indicators and backplane status reporting provide immediate feedback on port activity and module health. These features accelerate commissioning and reduce troubleshooting time during network maintenance.

FAQs

Can the IC200CMM020 operate as a Modbus Slave?No. This specific module is hardware-coded and firmware-optimized to function exclusively as a Modbus Master. If your application requires the VersaMax station to respond to an external master, you must utilize a different communication module or the CPU's built-in ports.
What cable length does the RS-485 interface support?The RS-485 standard typically supports distances up to 1200 meters (4000 feet) at lower baud rates. However, factors like cable quality and environmental EMI influence performance. We recommend using high-quality shielded twisted-pair cable for all 19200 bps installations.
Does this module require a separate power supply?The IC200CMM020 draws its operating power directly from the VersaMax backplane (460 mA at 5V). You do not need an external power connection for the module itself, though the RS-485 network may require termination resistors at the physical ends of the bus.
Is this module compatible with the VersaMax Micro series?The IC200CMM020 is a modular component designed for the Modular VersaMax system using NIUs or CPUs on carriers. It is not compatible with the fixed-I/O VersaMax Micro or Nano controllers.
