What is the Difference Between 2-wire and 4-wire RS-485?
Recently a customer asked what the difference is between 2-wire and 4-wire serial RS-485 communication. To answer this question it is helpful to have some understanding of the RS-485 standard. The problem is that "RS" stands for "Recommended Standard" and has not been treated by manufacturers as an absolute definition. The RS-485 standard was established by Electronic Industries Alliance, EIA, in 1983 as a half duplex multi-drop variation of the balanced or differential simplex signal standard, RS-422. Current standards for serial communication are typically established by the EIA and the Telecommunications Industry Association, TIA. The current standard for RS-485 was set in 1998 and is designated TIA/EIA-485-A...read more.

The ADAM-4914V Four-Channel Surge Protection Module Application Indicator
Most factories today are facing increasingly complex wiring systems with high voltages. Interference from these high voltage wires can cause serious damage to control systems. The result of such a surge is usually costly, as all the components in the control system may need to be replaced. The ADAM-4914V ensures protection against these surge voltages up to 4,000 voltages...read more.


Unbind the Limits of Analog I/O Modules in the ADAM-5510
Analog computing capacity is one of the key features of PC-based control. This is also the reason many users choose the ADAM-5510 PC-based controller in an automation system. However, in the past, the ADAM-5510 power board could only supply 10W for power consumption. Due to this reason, the ADAM-5510 main unit was capable of handling only one analog output module...read more.

Universal Network Controller UNO-2000 and Enterprise Information Automation Application
With the quick development of network technology, communication technology and "eAutomation" the informationalization path of enterprises also speeds up. However, during the process of enterprise information automation, large and medium national enterprises face the problem of integrating the existing DCS control information, status parameters and field information with enterprise information management to achieve the three-layer information system of ERP (enterprise resource planning), MES (manufacturing executive system) and PCS (production control system), and connecting the enterprise information management system seamlessly to the MIS and OA system...read more.
