1: Product scale to large and small two directions Great: I / O points up to 14336 points, 32 for the microprocessor, multi-CPU parallel, large memory, high speed scanning speed. Small: the whole structure to develop small modular structure, increase configuration flexibility, Henan plc interface, reducing costs. 2: PLC in a closed loop process control is used widely 3: 4 :. strengthening communication capabilities of new devices and modules PLC has introduced a high-end addition to the main CPU to increase processing speed using external, plc man-machine interface design, as well as with the processor Dedicated EPROM or RAM module of intelligent I / O modules, high-speed counting module, remote I / O modules. 5: diverse programming tools, features continue to improve, plc HMI manufacturers tend to standardize programming languages ??have a variety of simple or complex programming and programming software, using ladder, functional diagram, Statement List programming language, there are also high-end The PLC Instruction 6: development of fault-tolerant technology uses hot standby or parallel, a majority vote of work. 7: the pursuit of standardization of hardware and software. Third, the cartridge storage system software memory called system program memory. Memory storage application software known as the user program memory. Fourth, the input-output interface circuit. Live input interface circuit by the optical coupling circuit and computer input interface circuit, the role is a programmable logic controller and field control interface interface input channels. 2. Field output interface circuit from the output data register, and the interrupt request gating circuit integrated circuit, a programmable logic controller to perform the role of member of the scene corresponding control signal output by the field output interface circuit. Five function modules such as counting, positioning and other functional modules. VI plc HMI communications module manufacturers, Henan plc interface, provided by the Texas subfamily subfamily hydraulic machinery automation equipment Limited.
