Programmable logic controller programmable logic controllers what is a plc a plc (ie programmable logic controller) is a device that was invented to replace the necessary sequential relay circuits for machine controlthe plc works by looking at its inputs and depending upon their state, turning on/off its outputs. There are some advantages of programmable logic controller (plc) are given below, it has very faster scan time it has capable to communication with computer in plant it has great computational capabilities it has shorter training time required a wide range of control application. To know advantages of programmable logic controller download brochure: plc due to dynamic development, sequential control, counters and timers, ease of programming, reliable controlling capabilities , and ease of hardware usage programmable logic controllers are also utilized in various control system areas.
4-reduce space occupied by the traditional wired logic ( could be critical in some products) 5- some plcs can be connected to a human machine interface as an lcd which could show a lot of info the end user would get use of some of the disadvantages of a plc i came across : 1- you need a programmer (know-how) skill.
Programmable logic controller disadvantages and functions when we discuss about programmable logic controller disadvantages, it is also important to consider other aspects as the technology is still new, we need to learn more on how to use it.
