MES1A and MES1B Modbus TCP to Modbus ASCII/RTU converters are easy-to-use, cost-effective solutions for connecting new
and existing Modbus ASCII/RTU serial devices to TCP/IP networks. The MES1A provides this connection for Modbus devices
with RS-232 interfaces; the MES1B facilitates Modbus devices with RS-422 four-wire point-to-point interfaces, or RS-485 four or
two-wire multi-drop bus connections.

MES1A and MES1B are flexible devices that allow for many different modbus network configurations.

1.

Modbus ASCII/RTU slave devices can communicate over a TCP/IP network to Modbus TCP/IP masters.

2.

Modbus ASCII/RTU master devices can communicate over TCP/IP networks to modbus ASCII/RTU master devices

3.

Modbus ASCII/RTU slave devices can communicate over a TCP/IP network to other modbus ASCII/RTU devices.

In this mode 2 devices are required to allow the modbus serial protocol to tunnel over a TCP/IP network.


Through the use of both panel and DIN rail mounting options and support for screw terminal block interfaces for both power and
serial, MES1B is designed to meet a variety of industrial applications.
