Advantages of Programmable logic controller
The Programmable Logic Controller, PLC is basically a programmed interface in between the field input elements and the final control element. Advantages of PLC Reduced space : PLCs are completely solid state devices and hence are extremely compact in comparison to hard-wired controller where electro-mechanical devices are used. Higher Life and Reliability : These […]
RS 232 Signals
RS 232 stands for Recommended standard number 232. This interface is an age old, and yet it is being used for interconnecting DTE and DCE. It is also one of the maximum used standards for data exchange. The simplicity of configuration and huge capability has rendered this standard a very successful run in the interface […]
What is RS 232 ?
RS 232 stands for Recommended standard number 232. RS-232 ,as an interface, has been a standard from many years for interconnecting a Data Circuit Terminating Equipment (DCE) with a Data Terminal Equipment (DTE). Various forms of RS 232 interface are available in the market. However, being different in design and configuration, they are easy in […]
Null Modem cable
Null Modem Cable. A null modem cable is a form of RS-232 standard where the transmit and receive lines are cross linked. Normally a straight through serial cable is used with this kind of adapter. The adapter is pre configured with the necessary cross links. In some cables, handshake lines are also cross linked. The […]
Interface
An Interface is a common shared medium across which two different components of a computer system can exchange data or information. There are basically two types of interface: Hardware Interface Software Interface Majority of equipments which do processing of data contains a relatively restricted capability in terms of transmission of data. It is very uncommon […]
