The process of manufacturing involves a series of high level operations for producing a product. For proper sequencing of theses series of operations, one needs a good controller. Earlier, the task of sequencing was done by the use of relay wires for performing a particular task.
But, this method had a certain drawbacks such as difficulty in reprogramming the changes in production, controlling the logic systems, etc. So, in order to avoid all the earlier drawbacks and get better help, the Siemens Programmable Logic Controller or Siemens PLC is brought into use.
It is a digital computer exclusively designed for controlling machines, automation & for managing factory assembling lines. PLC’s are now widely used in automation techniques in all industries. It is very different from basic desktops that are created for input & output arrangement purpose.
The programming of PLC’s are done by a specialized programming language, ranging from Mnemonic instructions, ladder logics, FBD, IEC 61131-3 Standard-level, Structured form of texts, SFC, to C or basic programming languages that can be stored in non-volatile memory or in the batteries.
The Siemens PLC operates on the sum transmit logic feature. The sequencing process can be programmed & stored into the memory without being hardwired. The content stored in the memory can be edited or changed, easily.
It handles all types of binary inputs & outputs which are related to the logic. Hence, PLC’s are cost-effective, can be installed easily and are very trouble-free to use. They offer a good and effective controlling system to the users.
