The user can automatically raise and lower the MR9070 signal output, with two modes.

The first method: set the start point, end point and cycle times to start working.

The second: advanced mode, the signal changes are all set by parameters.

The input signal is converted into an output signal. For example:

The input frequency is converted into current signal, and the input range is converted from 0 ~ 1000Hz to 4 ~ 20mA

The change trend of input and output signals can be displayed by curve, and the acquisition time of curve can be set,It can also automatically display the curve in the range of maximum and minimum values at a certain time.

The signal is displayed as signal value or engineering quantity, and the signal value is linearly corresponding to the engineering quantity, such as 4-20mA The signal of corresponds to 0 ~ 100, that is, 4mA corresponds to 0, 12mA corresponds to 50 and 20mA corresponds to 100. This range can be changed through parameters.

Rotational speed

pulse quantitative

The best way to calculate the speed of the motor or gear is to use the pulse mode. The motor is usually in minutes. If one pulse is generated in one revolution of the motor, one minute is 3000 revolutions, then one second is 50 pulses.

= (per second) × Number of pulses per revolution

(per minute) = × 60

(per hour) = ×3600

①：Frequency and frequency value box

② : set the number of revolutions of the motor shaft, and the upper left corner is the time of one cycle

③ : pulse M

This function is used to simulate the engine speed. For example, the engine gear has 60 teeth, but now assuming that the engine gear has one tooth less and only 59 teeth, the speed can be measured through the empty space without teeth

The main purpose of pulse quantitative control is to simulate the flow quantitative control sensor, for example:

One liter of water flow from the turbine sensor generates 100 pulses through the sensor, so 10 liters of water is 1000 pulses. When writing the PLC quantitative program, the generator can be used for accurate simulation.

To input a symbol, first press the “IN” key to switch to figure 1-3 above, press the “T-ON” key to enter the down stroke symbol, and long press the “T-ON” key to enter the number “2” If you need to enter a space, press the “EXIT” key, and long press the “EXIT” key to enter the value “0”

① : press the “IN” key to pop up the numeric keypad for modification

② : press “IN” to pop up the interface of adding variables

③ : HEX / DEC (press the in key to switch between hexadecimal display and digital display)

④ : Scanning device. Scan the device address according to the selected variable attribute (see the figure below for details)

⑤ : unified address. Set the device address of other variables to the same address as the selected variable address

⑥ : delete a selected variable

⑦ : delete all variables

⑧ : return to and exit the interface, or press the “EXIT” key directly to exit

① : select the starting baud rate, press the “IN” key to enter the selection mode, confirm the selection, and press the “IN” key

② : end baud rate selection, press the “IN” key to enter the selection mode, confirm the selection, and press the “IN” key

③ : start address setting, press the “IN” key to enter the editing mode, and press the “IN” key to confirm editing

④ : end the address setting, press the “IN” key to enter the editing mode, and press the “IN” key to confirm the editing

⑤ : stop bit selection

⑥ : check bit setting

⑦ : set the timeout duration.

⑧ : start scanning the device and press the “IN” key to start (Note: scanning requires the address and instruction parameters of variables, so you must add a variable or use the existing variable before scanning the device)

⑨ : address table. If the device responds, it will automatically fill the address into the address table. After scanning, the address table will display the number of devices responded. As shown in the figure above, “Dev = 002” indicates that the scanned addresses range from 1 to 32, and only “001” and “002” respond to the scanning. Then move the cursor to “Addr list:” press the “IN” key to enter the address table, select the responded device address, press the “IN” key, the scanning interface will exit automatically, and the responded device variable address will be modified automatically

⑩ : return to and exit the interface, or press the “EXIT” key directly to exit

Recorder purpose:

in the process of on-site debugging, if the occurrence time of the problem is uncertain, the recorder function can be used to record the signal change trend in the form of curve. After recording, the historical data can also be exported to personal computer for printing or screenshot analysis.

Parameters:

Capacity: 20000 recording points (1 point equals 1 second)

Channel: two channels

Recording interval: 0.1s-999.9s

① : value of signal channel “1”

② : value of signal channel “2”

③ : scale of signal channel “1”

④ : storage occupancy

⑤ : scale of signal channel “2”

① : start recording. Corresponding to “IN” key

②：

③ : history. Corresponding to “OUT” key

④ : configuration. Corresponding to “FN” key

⑤：Reset key, corresponding to the key “REST” Long press the “REST” key to reset the recording process, but the recording history will be automatically saved, and restarting the recording will automatically delete the previous recording history

Start recording

Before using the recorder, the setting of the signal source is the most important part, so first determine what signal type to use as the signal source.

For example: to record the temperature of PT100 temperature sensor. Pressure transmitter with pressure value range of 0-100kpa.

The wiring diagram is shown in the figure below:

① : according to the user’s settings, the recorder will automatically calculate the length of time that can be recorded

② : the greater the interval, the longer the recording time will be

③ : ch1 signal source. For signal source setting, you can select “Output”/”Input”/”Modbus”/”Temp”/”CPU T”

④ : CH2 signal source. For signal source setting, you can select “OFF”/”Output”/”Input”/”MODBUS”/”Temp”/”CPU T”

⑤ : automatic range. The curve screen of mr9270 series displays 320 points. After using this function, the curve Y axis will be displayed in the range of maximum and minimum values within 320 points

⑥：return to and exit the interface, or press the “EXIT” key directly to exit

Start recording. Press the “IN” key to automatically pop up the time setting interface shown in the figure below. Press the “↑”, “↓”, “←” and “→” keys to set the time. After the time is set, press the “IN” key to confirm and automatically exit the time setting interface and start recording at the same time

“Recording” corresponds to the “IN” key

After recording, there will be some changes in the interface of keys.

“Recording” becomes “Stop”, and the icon of recording data will appear in the status bar of the screen

① : the previous row is the time when the cursor moves one step at a time, and the next row is the time length of each grid

② : storage occupancy bar

③ : Pause key, corresponding to the “IN” key. When recording is started, “Recording” will change to “Stop”. Long press the “IN” key to pause recording, and the record will be saved automatically. If you need to record again, you can only long press the “REST” key to reset the record before you can start recording again. Restarting recording will automatically delete the last recorded data

④ : icon for recording data. If the recording icon appears in the status bar, it indicates that the recorder is still recording, and if it disappears, it indicates that it stops

Press the “OUT” key to view the recorded history, and the key will change at the same time. For details, please refer to the figure below (Note: viewing the history in the process of recording will not affect the recording)

① : record / stop. Corresponding to the “IN” key, long press the “IN” key to pause the recording and save the recorded data at the same time

② : lock the cursor. Corresponding to the “T-ON” key, the function is to make the cursor not move, but only move the curve (use the direction key to move the cursor)

③ : real time curve / view history. Corresponding to “OUT” key

④：configuration. Corresponding to “FN” key

⑤ :press and hold the “REST” key to reset. Corresponding to “REST” key

⑥ : time scale -. Corresponding to the “O-TY” key, change the time length of the first grid

⑦ : step +. Corresponding to “”↑”” key, change the time length of each step of cursor movement, step – corresponding to “↓” key

⑧： time scale +. Corresponding to the “I-TY” key, change the time length of the first grid
