Solutions for various applications based on S7-1200PLC

S7-1200PLC is mainly oriented to simple and high-precision automation tasks. Its compact design, flexible configuration and powerful instruction set make it a solution for controlling various applications.

The CPU combines a microprocessor, an integrated power supply, input circuits, and output circuits into a compact housing to form a powerful PLC.

The CPU monitors inputs and changes outputs according to user program logic, which can include Boolean logic, counting, timing, complex math, and communication with other intelligent devices.

S7-1200 Hardware - Digital I/O

8-point, 16-point and 32-point input/output modules are available to meet different control needs.

In industrial control, some input quantities (temperature, pressure, flow, speed, etc.) are analog quantities, and some actuators (electric control valves and frequency converters, etc.) require the PLC to output analog signals, while the PLC's CPU can only process digital quantities.

The task of the analog I/O module is to realize A/D and D/A.

Programming tool STEP7 Basic-Features

STEP7 Basic is a highly integrated engineering configuration system developed by Siemens, including the task-oriented HMI intelligent configuration software Wincc Basic.

Hardware Configuration - Deleting Hardware Components

You can delete hardware configuration components in the device view or network view, and the deleted component addresses can be used by other components. You cannot delete the CPU and rack separately, you can only delete the entire PLC station in the network view or project tree.

After deleting the hardware components, you can compile the hardware configuration and perform a consistency check during compilation. If there is an error, an error message will be displayed and the error should be corrected and recompiled.
