The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment MM-EFS30K1M
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students MM-EFS30K1M.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language MM-EFS30K1M. In large and medium-sized PLC systems, structured text is often used to describe the relationship between the variables in the control system.
Mainly used for other programming languages more difficult to achieve the user program.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive. Analog input channel number: 8CH.

Voltage input
The analog input voltage: DC - 10 - 10V.
Digital output value: 32000 ~ 32000.
Current input
Analog input current: DC0 ~ 20mA.
Digital output value: 0 ~ 32000.
Analog input module for the external analog signal into the interface of the programmable controller.
Can choose the channel between the insulation, voltage input, current input, voltage / current mixed input, thermocouple input, temperature resistance (RTD) input for a variety of purposes, such as modules.
Filter high frequency interference.
Analog input module has been equipped with a first order lag filter.
The analog input signal with high frequency interference component can be obtained by using the first order lag filter.
Parameters can be set through the filter time constant, no program can be easy to uuse MM-EFS30K1M.
Execute event drivenn program through alarm output
Strengthen the implementation of the interrupt function according to the alarm output flag, easy to carry out preventive maintenance .
The measured value and the change rate of the analog input signal exceed the upper annd lower limits of the set,
Regardless of the procedure of the scan time, can be executed interrupt handling, quickly respond to abnormal conditions MM-EFS30K1M.
