Siemens PLCS7-300 series minicomputer: minicomputer control points within 256 points of general, adapted to control stand-alone control or small systems. Siemens minicomputer has S7-200: processing speed of 0.8 ~ 1.2ms; memory 2k; Digital 248 points; 35 analog way. Midrange: Control Point midrange generally not more than 2048 points, the device can be used to directly control the E8-D15PKFG, but also on a plurality of lower-level programmable controller for monitoring EYZ60-D15MP1, it is suitable for medium or large control of the control system. 6ES5 950-1AB61 6ES5 420-3BA11 6ES5 444-3AA11 6ES5 445-3AA12 6ES5 312-3AB11 6ES5 240-1AA21 6ES5 905-3RB21 6ES5 375-0LA11 6ES5 935-3LA12 6ES5 105-3RB31 6ES5 488-3LA31 6ES5 487-3LA11 6ES5 766 -0LB11 6ES5 766-0LA11 modular structure of modular programmable logic controller is the individual components of the PLC system into functional plc combination of several modules EYD60-D8MP1, such as CPU modules, input modules, output modules, power modules, etc. and so on. Where each module function is relatively simple, but increasingly rich variety of modules. For example, some of the programmable controller, in addition to - outside some basic I / O module, there are some special function modules, such as temperature detection module, position detection module, PID control module, communication module and so on. PLC modular structure is characterized by CPU, input and output modules are independent. Module size uniform, neat installation, I / O points selection freedom, installation, expansion, and easy maintenance.
