Profibus (Process Field Bus) Profibus may be a standard communication field-bus which is employed to use and spread the utilization of bit-serial in Automation field supported requirement of the sector device interface. Now a days There are two sorts of profibus utilized in industry. it's characterized by the cabling of purple single –pair RS485. Those cable use the quality DB9 or m12 connectors.   Profibus DP(Decentralized Peripherals)-   it is faster protocol profibus ,this is made for the communication between profibus masters and their remote I/O slaves. it's also operate using Sensors and actuators by employing a centralized controller in production industry to form the method control automatically. It has high data speed, low connection cost , it's huge application within production automation are usually realized by remote of I/O, frequency converters, Sensors and actuators. PROFIBUS DP is standardized under IEC 61158, which guarantees compa...

Plc (Programmable Logic Controller) Communication/PLC communication protocols. A program consists of 1 or more instructions that accomplish a task. Before writing the program in plc you'd wish to attach the module with PLC software by using communication port like RS232,Serial Communication,Modbus or Ethernet supported your application. you'd wish to offer the connection to all or any or any your input and out devices, Then you've to write down down the program in plc.. Ladder Logic is that the normal programming language . There are four basic steps within the operation of all PLCs; Input Scan, Program Scan, Output Scan, and Housekeeping. These steps continually happen during a repeating loop.        The communication protocol acts as an agreement between two or more communicating Devices. Extension modules PLC I/O number are often increased through certain additional modules by system extension through a extension lines. In PLC Each module can con...

What is counter A counter may be a digital circuit or device that counts the amount of products and returns predefined values supported clock pulse applications. The output of the counter are often wont to count the amount of pulses. The counter circuit is typically composed of several flip-flops connected within the cascade method. Counter automation and digitally based components are very widely used components.      Micro controller applications require external events or precise internal time delay generation and calculation of pulse frequency as required . These phenomena are often utilized in digital systems and automation. Both of those events are often performed by software techniques, but software loops for counting won't give accurate results, as little more important work isn't done. These problems are often corrected by timers and counters in micro controllers that are used as interrupts. Classification of counters In digital circuits, counters ...
