controller

pid کنترلر In the field of automation and instrumentation, it is one of the most central equipments of controllers, which has the task of controlling and automating the process. The word controller is usually associated with the words sensor and actuator , meaning actuator, which in interaction with each other can form a control loop or a control loop. Controllers, in terms of efficiency and programmability, are analog or digital. The number of inputs and outputs, control mechanism (differential, derivative, disproportionate) (proportional – integral – derivative), mechanical or electrical are of different types.
Nowadays, with the advancement of computer hardware and software, by installing the necessary software and hardware on the computer, it is possible to have a non-professional programmable logic controller, which, of course, in the industry due to the high need for safety against noise, heat and cold. Humidity, dust, and common flats do not make sense. Many companies in the world produce PLC, the most famous of which are Siemens and Amron in Iran.
To choose a controller or programmable controller, the following should be considered:
Number of inputs and outputs
Control mechanism
type of industrial protocol that supports
analog or digital inputs and outputs
Ability to increase input and output cards
Ability to have two communication networks Simultaneous (redundancy)
Software to work with
memory controller and CPU speed controller
and ...
