Product description
The CT7P70500470CW24 CPU is the control center of the programmable controller, which is equivalent to the human brain. CPU- generally consists of a control circuit, an arithmetic and a register. These circuits are usually packaged on an integrated chip. The CPU is connected with the storage unit and the input and output C] circuit through the address bus, data bus and control bus. The functions of the CPU are as follows: it works under the control of the system monitoring program, writes the state of the external input signal into the input image storage area by scanning mode, after the PLC enters the running state, reads the user instructions from the memory one by one, carries out the data transmission, logical operations, arithmetic operations, etc. according to the tasks specified in the instructions, and then sends the results to the output image storage area.
CT7P70500470CW24CPU commonly used microprocessors include general-purpose microprocessors, single-chip computers and bit-chip computers. General purpose microprocessors are common such as Intel's 8086.80186, to the Pentium series chips, single-chip microprocessors such as Intel's MCS-96 series microprocessors, and bit-chip microprocessors such as AMD 2900 series microprocessors. The CPU of small PLC mostly uses single chip microcomputer or dedicated CPU, the CPU of medium-sized PLC mostly uses 16 bit microprocessor or single chip microcomputer, and the CPU of large PLC uses high-speed bit chip processor and has high-speed processing capability.
