modbus technology

Modbus Technology

Modbus is a widely used serial based communications protocol that is usually transmitted over copper wires or Ethernet cabling. Publihed in 1979, Modbus is a free and easy to use protocol that allows multiple devices to be connected to the same network. There're two forms of Modbus protocols: Modbus RTU which communicates over two copper wires and Modbus TCP which communicates over an Ethernet cable.

automated toll roads

4 Types of Automated Toll Road Systems

Toll Roads are public or private roadways that charge drivers a fee for access or passage. Some toll roads have an operator that collects payment from drivers, issues a receipt and manually raises a barrier granting passage. Automated toll booth payment systems allow drivers to insert payment into a machine that prints a receipt and raises a barrier automatically upon receipt of required payment. Some automated systems have open roads without barriers and involve wireless transponders where drivers have prepaid accounts or payments are billed and collected.

RS-485 Communication

RS-485 is a serial based multipoint communication and electrical specification of a two-wire, half-duplex, multipoint serial communications channel. RS-485 allows for lower cost network communication as the cabling is inexpensive and transmits across a large distance. RS-485 equipment can be controlled by a set of commands. RS-485 is widely used in computer automation systems (building automation, machine automation and factory automation and other systems).

3 Types of Easy-to-use Remote Data Acquisition Modules

Data acquisition is the process of acquiring real world information from sensors and converting the sample data into numeric values that can be manipulated by a computer. By using remote data acquisition modules, users can monitor and control their applications on central computers based on the information received from remote data acquisition modules, and implement control logic operations like automatically turning on a fan based on the temperature, turning on a pump based on the tank level, etc.

3 Things You Should Consider When Choosing an Energy Meter

Intelligent power meters and monitoring equipment can be used to show electricity consumption, help with load management, transformer monitoring, and power monitoring. Smart Power Meters give you access to real-time power consumption and can save you time and money since changes can be made to reduce energy usage automatically when it's not needed. Touch Screen PLC's, data loggers, Programmable Automation Controllers, and PC's running SCADA software can be used for control, monitoring and displaying the data in a way that's easy to understand and analyze.

3 Easy-to-use Software for Data Logging

Data logging is the process of getting data from sensors and analyze the data on a PC. It involves recording data over time in order to get samples of real world physical information and converting the resulting samples into digital numeric values that can be manipulated by a computer. A data logging system can collect various types of information, including temperatures, electrical currents, voltage, sound frequencies, vibrations, times, light intensities, pressure, etc. Choosing an easy to use data logging software is very important in improving users’ efficiency and saving cost. Software like InduSoft, eLogger, and EZ Data Logger can easily be incorporated with existing data acquisition systems and remote monitoring and control systems to show the status of equipment, send email or text alarms to users, log and analyze data, implement control demands and generate reports.

3 Types of Wireless Technology

Wireless applications are flexible, clean and convenient. Wireless solutions can help when you want to communicate with a tank out in a remote area, want to check the status of something from a remote location, or when you don’t want to install any wires. Here is a short list of some types of wireless technology.
