A new line of Modbus based IO modules for Data Acquisition and other applications is now available now from CrispTech . These IO modules offer a highly reliable, low cost solution for Distributed IO applications using either standalone SCADA systems or with PLC attached IO using Modbus communications. They are portable, easily integrate with any existing Modbus networks and are simple to install and monitor. Various types of digital and analogue IO modules are available for different requirements. The digital modules have visible LED indicators of IO status and all have fault diagnostic LEDs.
These modules are configured as Modbus slaves and will easily communicate with a Modbus Master such as SCADA/PLC/HMI. They connect using a 2 wire RS485 interface with Modbus RTU Protocol and a range of interface converters are available for RS232, Ethernet and other systems.
IO Studio software is provided at no charge and this enables configuration, real-time status checking and some diagnostics from a local PC.
An additional software package to be released in the next few months will also allow you to create a mini SCADA system for simple applications. This will provide further collection and analysis of data in Real Time and provide data logging, data export, alarming, and a real-time graphical environment to support systems of up to 1024 tags.
