S71200 Siemens PLC programming control in parsing -

by:Coolmay     2020-06-06
S7- 1200 main PLC is simple and high precision automation tasks, its compact design, flexible configuration and has a powerful set of instructions, S7 - 1200 PLC controller combination of these characteristics make it be control all kinds of application solutions.

CPU to integrate the microprocessor, power supply, input and output circuit into a compact design of the shell to form a powerful PLC.

CPU according to the user program logic to monitor the input and change the output, the user program can contain Boolean logic, counting, timing, complex mathematical operation, and communicate with other intelligent devices.

can choose 8, 16 and 32 points of input quantity input/output module, control to meet different needs.

in industrial control, some input ( Temperature, pressure, flow rate, rotational speed, etc. ) Is analog, some actuators ( Electric control valve and inverter, etc. ) For PLC output analog signals, and the PLC controller CPU can handle only digital quantity.

analog I/O module's task is to achieve A/D and D/A.

programming tool STEP7 Basic - Characteristics of

STEP7, Basic configuration system is developed by Siemens high integration project, including task oriented intelligent HMI configuration software Wincc Basic.

hardware configuration - - - - - - - The configuration tasks hardware configuration -

- - - - - - Configuration task is in the device and the network editor to generate a corresponding simulation system with the actual hardware systems.

hardware configuration - - - - - - - Can remove hardware components

delete equipment view or hardware configuration in the view of network components, the deleted component address available to other components. Can't delete individual CPU and frame, only in the network view or delete the whole PLC station project in the tree.

after delete hardware components, the hardware configuration can be compiled, compile time consistency check, if there are any errors will display an error message, should be recompiled after correction.

so on Siemens S7 - What are you familiar with 1200 series PLC controller of cognitive point?
