FACILITIES AND PROCESSES AUTOMATION

PROCESS ACTUATOR Actuators are devices that are directly connected to control device in the field to achieve control actions. It may be coil, lamp, relay, vibrator, solenoid valves, cylinders, electric motor, pump, and so on. Another name for output devices is ACTUATOR. They are powered with any of this form of energies electrical, pneumatic and or hydraulic energy. Some actuator performs action without given feedback to elements controlling them while some gives feedback about their current position or status of mechanism they are attached to. Some actuators make use of digital output signal to perform operations while some uses analogue signals to perform operation. Some makes use of only one source of energy to initiate control actions while some combines two sources of energy to initiate control actions such as pneumatic and electric power as in the case of pneumatic components . Some actuator can convert mechanical rotational motion to linear motion or vice versa wh

AC SERVO MOTOR Precision, Speed, Accuracy, Throughput and Analytical functions are the design target of every control system.  Servo motor is an electric motor designed for precision purposes most especially for position, velocity and torque control capability which makes motion/movement more accurate. Servo motor's design unlike other synchronous motor takes advantage of feedback feature to deliver accurate motion as profiled in the program software. Like all other motors, servo motor consist of Rotor and Stator but in addition has encoder/resolver as the feedback component while some are with or without brake system depending on applications Other electric motor may be started directly by applying the voltage using some forms of switching devices such as contactor or switches while others may be powered with frequency inverters where there may be need for operation speed to be regulated but servo motor does not follow suit. It is being power by

INDUSTRIAL COMMUNICATION PROTOCOL Either we like to be a System Engineer that understood well the intricacies of computer communication or not, it is one of the duty of anyone involved in Electrical  Control, Instrumentation and Automation to be familiar with the aspect related to their field in which now i will discuss with you. Listed below are the list of communication protocol as formulated by different vendors but the most commonly used in the Industrial machine application to connect PLC, HMI, Drives, Field devices, and more are ETHERNET, PROFIBUS, DEVICENET, AS-i, PPI, MPI, POWERLINK, ANYBUS, CANBUS, PROFINET, BacNet, HART, MODBUS,  SERCOS COMMUNICATION PROTOCOLS AS-i : Actuator-sensor interface, a low level 2-wire bus establishing power and communications to basic digital and analog devices BSAP : Bristol Standard Asynchronous Protocol, developed by Bristol Babcock Inc. CIP : (Common Industrial Protocol) – can be treated as application la
