MESR900 Modbus Gateways bridge devices on Modbus serial networks (RS-232, RS-422 or RS-485) with those on Modbus TCP networks, allowing seamless integration. Serial ports can be accessed over a LAN or WAN using Direct IP Mode connections. Supporting up to 16 masters and 32 slaves, these gateways feature autodetecting10/100 copper and fiber optic options. Easy-to-use software is designed for Windows 2000, 2003 Server, XP, Vista, 2008 Server and Windows 7. Serial data rates up to 230 kbps ensure maximum network flexibility. MESR9xx gateways are built for use in industrial environments, featuring a slim IP30 DIN rail mountable case. They operate from a range of DC power supply voltages and have pluggable terminal block connectors. An external power supply, sold separately, is required. The MESR92x units have an additional Ethernet port which functions much like an Ethernet Switch, allowing pass-through connectivity for other Ethernet devices. This port can also be used to “daisy chain” multiple gateways. MESR90x units have one Ethernet port. B&B Electronics’ Vlinx™ is your number one choice for Ethernet to Serial conversion.

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.
Vlinx™ MESR Configuration Screens for this Application
Serial & Ethernet Masters, Serial & Ethernet Slaves
MESR9xx modules can also integrate multiple master devices onto serial and Ethernet networks.
Vlinx™ MESR Configuration Screens for this Application
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.
