Seamlessly Integrate Your Modbus TCP and Modbus Serial Networks. Fiber Ethernet and built-in Ethernet Pass-Through Options Available!

Solve most any Modbus conversion challenge with the MESR Modbus Gateway

• ASCII to RTU Conversion
• ASCII or RTU to Modbus TCP Conversion
• Remap conflicting Modbus ID's
• Add multiple masters to Modbus networks
• Prioritize messages based on IP address, Modbus ID, and Function code
• Convert mismatched serial baud rates and settings
• Route Modbus traffic based on Modbus ID

MESR Modbus Gateways bridge devices on Modbus serial networks (RS-232, RS-422 or RS-485) with those on Modbus TCP networks, allowing seamless integration of any Modbus device. Each serial port is accessible over a LAN or WAN by up to 16 simultaneous Modbus TCP masters. All Vlinx™ MESR gateways feature auto detecting 10/100Base T copper and fiber optic connections.

Simple Installation and Setup

• Removable terminal blocks simplify power and data connections
• Slimline IP30 DIN mount enclosure minimizes footprint
• Simple configuration through the built-in web server, or Windows configuration software
• Built-in traffic monitor for instant verification of successful installation and simple network diagnostics
• Optional pass-through Ethernet port eliminates need for additional Ethernet switch port
• Optional Fiber Optic Ethernet connections for long-distance and total noise immunity

Specifications

• Serial ports work with RS-232, RS-422/485 and are software configurable
• Modbus RTU or ASCII
• Supports up to 16 simultaneous Modbus TCP masters
• Modbus messaging priority control (source or function code selectable)
• Auto detecting 10/100 Ethernet port
• Operating Temperature: -34 to 74°C
• 10 to 48 VDC Operation
• Management: Multiple TCP/IP Client Sessions

Applications

• Industrial devices (PLCs, drives, motor controls, process analyzers)
• OPC server applications
• PC controllers (Think and Do, Steeplechase)

Ethernet Master Serial Slaves
MESR9xx modules can be used to integrate serial slave devices on a MODBUS TCP network. This allows TCP Masters to control serial slave devices.

Serial & Ethernet Masters, Serial & Ethernet Slaves
MESR9xx modules can also integrate multiple master devices onto serial and Ethernet networks.

Two Identical Hard Coded Slaves
In this scenario, two slave devices that are hard coded with the same ID are required. This is accomplished by placing them on different serial ports.

Serial Masters with IP Slaves
Serial Masters can be used to control IP slaves

Identical Networks
In this scenario, identical or backup production lines can be controlled by the same IP Master. This allows the duplicate networks to be configured identically, saving documentation and maintenance time.
