Overview
The ProSoft ILX34-MBS485 (also designated as ILX34-MBS36) is a serial gateway module built on the EtherNet/IP communication protocol. It is engineered to enable seamless integration between EtherNet/IP systems—such as the CompactLogix L1 processor or 1734 Point I/O system—and Modbus RS485 devices.
Core Specifications
- Communication Protocol: Modbus RTU (RS485)
- Maximum Data Bits: 32 bits (maximum data length per command)
- Maximum Slave Nodes: 31 units (supports up to 31 Modbus slave devices)
- Maximum Modbus Commands: 30 commands (maximum number of commands processable per cycle)
- Hardware Configuration: Supports 5.1V DC power supply; standard input/output level is 24V DC
Key Features
- Bidirectional Communication: Operates as either a Modbus Master or Slave, significantly enhancing system flexibility for diverse industrial setups.
- No Configuration Software Required: All parameters and logic configurations are completed directly via RSLogix 5000 or Studio 5000, eliminating the need for dedicated third-party software.
- Rich Communication Capabilities: Supports Report and Request function blocks, compatible with both ASCII and decimal data formats, and compliant with Modbus 1.0b/1.1b standards.
- Robust Hardware Design: Enables long-distance communication up to 4,800 meters and features electrical isolation (depending on the specific model), ensuring stable operation even in harsh industrial environments.
Structure & Components
- Module Form Factor: Standard 1734-I/O rack-mount module, fully compatible with Rockwell Automation’s Point I/O system for streamlined installation.
- Port Configuration: Equipped with an RS485 communication port that supports differential signal transmission, effectively reducing communication bit error rates.
- Internal Logic: Integrates a built-in Modbus protocol stack, capable of directly processing Modbus command frames without additional external processing units.
Application Areas
- Factory Automation: Connects existing Modbus fieldbus devices (including frequency converters, temperature controllers, and flowmeters) to the EtherNet/IP network, enabling centralized data collection and unified system control.
- Process Control: In industries such as oil and gas, chemical processing, and pharmaceuticals, it integrates field devices from multiple brands to boost overall system integration efficiency.
- Building & Facility Management: Used to link environmental monitoring sensors and energy management equipment for smart building control solutions.
Installation & Maintenance
Installation Steps
- Hardware Configuration: Insert the ILX34-MBS485 module into the 1734-I/O rack, and connect it to the EtherNet/IP network via the 1734-AENTR adapter module.
- Logic Programming: Import AOI (Add-On Instruction) routines (e.g., ILX34-MBS485_AddOn_Rung) into RSLogix 5000/Studio 5000, then configure key parameters such as slave address, baud rate, and parity check settings.
- Network Connection: Use shielded twisted-pair cables to connect Modbus devices to the module’s RS485 port, ensuring correct configuration of signal termination resistors for optimal signal integrity.
Maintenance Guidelines
- Environmental Monitoring: Despite its industrial-grade protection, the module should be installed in dry environments free from corrosive gases to extend service life.
- Electrical Inspection: Regularly check the connectors of power cables and communication lines to prevent communication interruptions caused by loosening due to mechanical vibration.
- Logic Updates: When performing logic updates via Studio 5000, ensure the device is in the offline state to avoid system malfunctions caused by incorrect program writing.
