The main function is to acquire information from the process, in order to provide a summary view of the status, promptly report the occurrence of alarms, record all information and generate reports for production or quality managers. The sending of data to the field devices is usually limited ...
At the control level, PLCs communicate with field components at the physical level using a variety of communication protocols depending on the component. PLCs also use different communication protocols to communicate over networks and with wireless devices. Modbus RTU is a serial communication protocol...

The MODBUS/TCP protocol was released as a (de facto) automation standard. Modbus communication protocol is a general communication protocol that has been widely used in today's industrial control field.
Release 7.This release largely focused on performance improvements, such as decreasing latency, improving quality of service (QoS) and improving voice over IP (VoIP). This release also worked on Evolved HSPA (HSPA+),near-field communication(NFC) integration and EDGE Evolution. ...
In this article, we break down the "family tree" of Robot Vision and show where it fits within the wider field of Signal Processing.What is Robot Vision?In basic terms, Robot Vision involves using a combination of camera hardware and computer algorithms to allow robots to process visual ...
In light of the performance and simplicity of chromates for corrosion protection, it is clear that replacements are not only needed, but will also ideally be required to meet acceptable anti-corrosion performance (which is now industrially expected and will also be demanded by consumers who have ...
Fieldbuses– Connecting PLCs to remote I/O devices, drives, sensors using fieldbus networks like Profibus, Modbus RTU, and DeviceNet. Wireless– Technologies like WiFi and cellular allowing PLCs to communicate wirelessly with mobile HMIs, data historians, asset management systems, and remote troubles...
Since he first announced myRA at Tuesday night's State of the Union speech, President Obama wasted no time in signing the executive order to make it happen the second morning, before he started his road trip to tour his newest idea. What is myRA?
In developing medicinal plant cultivation, competing with food crops should be avoided as much as possible, and the impact on the production of major grain crops should be minimized. Therefore, the full utilization of soil resources in forests, mountains, and wasteland is advocated, and ...
