plc how to realize multi-position selection work

Foshan Qingjun Electronics Co., Ltd. launched a simple PLC all-in-one machine covers the following models:

8 into 8 out (optional relay output, transistor output)

12 into 12 out (optional relay output, transistor output)

16 into 16 out (optional relay output, transistor output)

general Electrical engineers can read and understand and on-site programming, with simple programming, easy to use, greatly reducing the cost of use. At the same time can also be used as a multi-channel time relay module, each channel can be independent or linkage control, to achieve more complex functions than the traditional single-circuit time relay.

And it has the following features:

Support two pulse outputs, each with an adjustable frequency range of 100Hz~150KHz;

Support switching between Chinese/English interfaces;

Support logic and, or, addition and subtraction operations;

Support 20 groups of programs working in parallel;

Support 25 timers, 50 counters, 50 timers;

Support 25 timers, 50 counters, 50 timers. counters, 50 timers;

Support 19 external registers (can realize access to external devices, data exchange and processing)

Delay precision 0.01 seconds

Input point compatible with NPN-type, PNP-type switching signals

Optional 2 12-bit analog inputs (can realize 0-20mA ,4-20mA, 0~5V, 0~10V, 0~5V, 0~5V, 0~5V, 0~5V, 0~5V, 0~5V, 0~5V, 0~5V, 0~10V, 0~10V, 0~10V, 0~10V, 0~10V). ~5V, 0~10V signal detection);

Optional 2-channel high-precision analog output (0~20mA, 4~20mA, 0~5V, 0~10V output);

Optional 2-channel high-speed pulse output

Optional RS485 MODBUS-RTU communication

Support the signal jump trigger;

Support the connection of all the company's switching signals.

Support to connect all the company's 485 communication modules to expand the output port;

Support to connect the touch screen;

Can be any combination of almanac control;

No need for ladder programming and so on

Can be used to replace the ordinary PLC:

Customized key simulation of the start-pause-emergency-stop function, a number of switching inputs can be connected to a variety of sensors to achieve PLC action process logic operation, output function of customized programming, multiple time periods independent or combined timing function.

Can replace multiple time relays:

Each programmed combination, the function is more powerful than the time relay, time accurate to 0.01 seconds. Can realize the year, month, date, day of the week, time and other arbitrary combinations, triggering a series of specific actions

Can replace the PLC analog current module, voltage module: internal analog units of operation, to achieve the programming intuitive

Program encryption: you can set up a good encryption of the program, to avoid being altered by others.

Offline management: no need to connect to the computer, directly on the control panel for editing and setting, using high-definition color LCD, the operator interface is available in Chinese Simplified Chinese, Chinese Traditional Chinese, English, menu management, instructions, input content corresponding to the display, easy to learn and easy to understand, without the need for professional engineers that is to learn, eliminating the need to learn the ladder diagrams to bother.
