Vlinx Modbus Ethernet to Serial Gateways

Details

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
Features Benefits
Slim, Industrial Enclosure Save DIN rail space while maintaining industrial ratings
Modbus Master/Slave Flexibility Modbus master or slave can be on any serial port or on the Ethernet port. Customizable to your application.
Web Server, Configuration Software Program through web browser or local port. Same user interface; no training required
Complete Fiber Options Connect to all fiber networks in your plant without converting to copper connections
Low Latency, High Throughput View status in real time


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.

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.

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.
