Small, Economical, and Easy to Configure, Modbus Ethernet Serial Servers

MES1A and MES1B Modbus ASCII/RTU to Modbus TCP converters are easy-to-use, cost-effective solutions for connecting Modbus serial devices to TCP/IP networks. Model MES1A handles the RS-232 and model MES1B handles both the RS-422, and RS 485.

MES1A and MES1B will handle most Modbus network configurations including the following:

• Modbus ASCII/RTU slave devices can communicate over a TCP/IP network to Modbus TCP/IP masters.
• Modbus ASCII/RTU master devices can communicate over TCP/IP networks to Modbus ASCII/RTU master devices.
• Modbus ASCII/RTU slave devices can communicate over a TCP/IP network to other Modbus ASCII/RTU devices. Two 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.
