Mechanical system in PLC

There are two mechanic design types used occasionally for system-sistem PLC : Single box Type , and Type Modular and Rak. Single box type generally applied for small fairish controller of which can be programmed and marketed in the form of inwrought packaging, complete with energy?power allowance, processor, memory, and units input/output. See picture under

Usually, a kind of this PLC type can have 40 point of input/output and an memory unit which storage can around 300 to 1000 instructions.

Modular type consisted of modules that is separate, his(its each to ration energy?power, processor, other modules, often stuck into at rail lines in a base. Rack Type can be utilized for all controller measure program and has multifarious tidy functional unit for independent modules of which can be stuck into socket-socket at a base is in the form of Rak. See picture under ;

Combination of Module needed to a the application of certain determined by user and modules selected then stuck at rack. Because of item relative easy for we to add number of extensions input/output with simply sticking additional modules or enlarge memory measure with simply sticking addition memory units.

Programs packed into one of memory PLC by using a programming peripheral generally is not jointed permanently to PLC and movable out of one controllers to other controllers without disturbing operations is being implemented. Oparation to PLC , programming peripheral is not necessarily be jointed to PLC because this peripheral will only remove program which we are create to memory PLC.
