Siemens 6ra8081-6ds22-0aa0 is stored, and then output to the output interface to control the external driver. Composition: CPU is composed of controller, arithmetic unit and register. These circuits are integrated on one chip. CPU is connected with i/o interface circuit through address line and data line. 2. Memory semiconductor circuit with memory function. It is divided into system program memory and user memory. System program memory is used to store system programs, including management programs, monitoring programs, and interpreted compilers that compile user programs. It is composed of read-only memory and ROM. The content used by the manufacturer cannot be changed, and the power failure does not disappear. User memory: it is divided into user program storage area and working data storage area. It consists of randoring and control in all walks of life and various occasions. The powerful function of S7-200 series enables it to realize complex control functions whether in independent operation or connected into a network. Therefore, S7-200 series has a very high performance / price ratio, S7-200 series * is shown in the following aspects: * extremely high reliability * extremely rich instruction set * easy to master * convenient operation * rich built-in set * ability * real-time characteristics * strong communication ability * rich expansion module SIMATIC S7-200 programmable controller order model: 6es7211-0aa23-0xb0 CPU 221 dc/dc/dc 6 input /4 output 6es7211-0ba23-0xb0 CPU 221 ac/dc/ relay 6 6ra7018-6dv62-0siemens/ Siemens 6sl3054-0ej01- 1BA0
