xPico-Wifi Module with Modbus TCP to Modbus

Get xPico-WiFi capabilities now with Modbus.  This module adds Modbus/TCP on the Ethernet side to Modbus/RTU or Modbus/ASCII on the serial side. When attached to a Modbus serial slave(s) it converts Modbus/TCP requests from 1 or 2 clients on the network into serial Modbus/RTU or /ASCII requests. Modbus serial responses are converted back to Modbus/TCP and delivered to the original client. This Device Server allows users to integrate new and existing Modbus/RTU and Modbus/ASCII serial devices to newer TCP/IP network-based devices. When it comes to data communications for industrial control systems, Modbus is supported by the most manufacturers. The Modbus/RTU protocol defines how a “master” device polls one or more “slave” devices to read and write data in real time over RS-232, RS-422, or RS-485 serial data communication. Although not the most powerful protocol available, its rare simplicity allows not only rapid implementation but also enough flexibility to be applied in a large number of industrial situations. Modbus/TCP, an extension of Modbus/RTU, defines how Modbus/RTU and Modbus/ASCII messages are encoded within and transported over TCP/IP-based networks. Modbus/TCP is just as simple to implement and flexible to apply as the original Modbus/RTU. Learn more about the specifications for both online at modbus.org.
