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.
