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. The serial ports can
be accessed over a LAN or WAN using Direct IP Mode
connections. Supporting up to 16 masters and 32 slaves, the
gateways feature autodetecting10/100 copper and fiber optic
options. The easy to use software is designed for Win XP, Vista,
Win 7 and Windows 2003/2008 Server, features Modbus
messaging priority control and allows management through multiple
TCP/IP client sessions. Serial data rates up to 230 kbps ensure
maximum network flexibility. MESR 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.
MESR424 series gateways can be powered via a barrel connector
or a terminal block. (An external power supply is required; sold
separately.) The MESR424 has 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.
