PROGRAMMABLE LOGIC CONTROL – Arktika.

Preface: pages 1,2,3,5 of the eBook.The digital book (or eBook), entitled:''PLC: PROGRAMMABLE LOGIC CONTROLLER – ARKTIKA''describes the construction, syntax and programming of a system capable of processing Boolean operations and capable of intercommunicating with other circuit parts electrically connected to it, such as digital integrated circuits.The processing logic is continuous and can be programmed to perform only the necessary operations, characteristics that equate it to a PLC even if designed for teaching and study purposes, in particular of Boolean algebra.The processing unit responsible for processing the calculations is based on an electronic architecture installed on a CPLD (Complex Programmable Logic Device) integrated circuit, given the flexibility of use of the latter.The main support where all the system electronics are housed is a commercial board where the CPLD programmable logic integrated circuit and the primary supports such as stabilized power supply, connectors to connect the complementary circuit modules, LEDs, etc. are already soldered. simplifying hardware construction.• The text includes attachments, the most important of which are:- files (.qpf), (.qsf), (.pof) to program the CPLD integrated circuit in addition to the Verilog file (.v) which describes the processing architecture;- graphic diagram of the processing architecture;- communication protocol for programming via PC;- 34 programming examples to test the system;• Other attachments concern:- files to create the printed circuits of the modules that will attach to the main board;- files (.qpf), (.qsf), (.pof), (.v) to program the CPLD integrated circuit and to be used for some simple tests of hardware robustness against external interference.The pages of this title have been curated to be viewed by ebook_readers, tablets and PCs.An intensive use of schematic drawings is made, exploiting the characteristic of including a lot of information that can be consulted in an intuitive way given the characteristic of the universal language.The same thing also applies to photos, in color and with resolutions designed to enlarge the details as well as making the theme more interesting.
