When the analog input has a thermocouple type, it can only do up to 15 channels, of which AD4 is the ambient temperature of the thermocouple. 16 channels are possible without the thermocouple type.

The value of the thermistor NTC is read in the 16thregisters starting at R23660.

Except the thermistor NTC,all types of analog readings are read directly by D[8030]~D[8045],

so analog input type needs to be set as below:

Namely, the 5th R23944 must be set less than 4.

R23960 starts with a zero correction value and defaults to 0.

R23960 starts with a zero correction value and default is 0 (Namely, size correction).

R23980 starts with a negative temperature amplification. The default is 4633 (temporarily only have negative temperature amplification).

The 16 registers starting from R23620 are 0~10V or 0~20mA corresponding values, that is, real-time sampled values.

5.1.5 Analog input sampling

Filtering cycles=( R23600~R23615)* PLC scanning time, if R23600=1, sample one time each scan circle and change the 1stanalog value for one time. The larger R23600~R23615 value is, the result is more stable.

R23600~R23615 is filtering cycles, default is 100 (Range 2~20000);

D8073 is smoothing filter coefficients of all analog input, range: 0~999

5.1.6 Analog input program example:

Below is an example of the CX3G 1 channel temperature analog AD0 acquisition. The program reads the values as follows:

CX3G/FX3GC PLC Programming manual

Connect the signal terminal of the temperature sensor to the AD0 input of the PLC and the other end to the GND of the analog input port.

When the PLC is running, the value of the data register D8030 corresponding to AD0 will be transmitted to D0, the value of D0 will be put into D10 after floating point operation,

and then the floating point number division operation will be performed on D10, and then operation result will be put into D20, the result D20 is the actual Temperature value.

In the ladder diagram, you can also directly divide the value of D8030.

Note: When the input is 0-10V analog, the actual analog value = register reading / 400;

When the input is temperature, the actual temperature value = register reading/10; When the input is 0-20mA analog, the actual analog value = register reading / 200;

When the input is 4-20 mA analog, the actual analog value = register reading / 250 + 4.

The analog correction is corrected for the size. The following figure is an example of correcting the AD0 temperature after acquisition:

If the current temperature is 37.9℃,the actual test is 47.9 ° C, the error is 10 ° C, you need to

modify the size correction register, show as below:

In the above figure, when M0 is closed, the value -100 is transmitted to the correction register R23960, and now you can see that the value of the actual measured temperature D20 is close to the actual temperature which is 37.9 °C.

5.2 Analog output

Analog output range 0~4000, precision is 12 bit. Support TO instruction or register assignment operation directly.

Adopts TO K0 K0 D500 K8, 8 channels 0~10V or 0~20mA analog output.

When the analog output is current, the bit of D8058 needs to be set:

When the default D8058.0~D8058.7=0, it means 0~20mA; when D8058.0~D8058.7=1, it means 4~20mA.

For example:

Below shows the 0-10V voltage analog output.

At this point, use a multimeter to check the voltage of the DA0 terminal, that is, the multimeter's red pen is connected to the DA0 terminal, and the black pen is connected to the GND terminal. The multimeter is displaying 5V voltage value.

7.1 high speed pulse output

Coolmay CX3G default has 8 channels high speed pulse, Y0-Y3 each 100KHz, Y4-Y7 each 10KHz,variable speed supported, the initial/final speed of start/stop is 0, diagram as below: (take accelerate and decelerate time D8148 as an example).

Acceleration/deceleration time T calculation= (target speed-current speed) * acceleration/deceleration time÷maximum speed. For example, target speed = 50000, current speed = 20000, acceleration time 100 (ms), maximum speed = 100,000, T = 30 ms. CX3G: 8 channels of pulse, the last 4 channels of acceleration and deceleration = D8148, the maximum speed is D8146, D8147. PLSY, ZRN, PLSV, DRVI, DRVA, DVIT, DSZR, only Y0-Y3 supports DVIT (interrupt positioning), DSZR (originary return with DOG search) instructions.

The original FX3G pulse program can be used directly. All the instruction support 8 channels pulse, except DVIT、DSZR which support 4 channels.

D8340 shows the current address of X axis，D8350 shows the current address of Y axis。 In CoolMay 3G PLC，interpolation motion still adopts DPLSR for pulse output.

Description of the Operand:

S.+2 represents the X-axis target address. S.+4 represents the Y-axis target address. D.: Specify the Y number with pulse output (currently only Y0 is supported), and the default Y1 is another axis. X axis: Y0 pulse, Y4 direction Y axis: Y1 pulse, Y5 direction

In the center interpolation mode:

S.+6 represents the center X coordinate address. S.+8 represents the center Y coordinate address.

In radius interpolation mode:

S.+6 represents the radius length. When it is positive, the path is a small circle; when it is a negative value, the path is a large circle.

For example: DPLSR D100 D102 D104 Y000 In the linear interpolation: D100 speed, D102 is the X-axis target address, and D104 is the Y-axis target address.Y0 and Y1 respectively pulse the X-axis and Y-axis.

CX3G/FX3GC PLC Programming manual

In the Center interpolation: D100 speed, D102 is the X-axis target address, D104 is the Y-axis target address, and D106 is the center X address. D108 is the center Y address. Y0 and Y1 respectively pulse the X-axis and Y-axis.

Note 1: The current address of X and Y must be on the same circle as the destination address. Note 2: When the current address coincides with the target address, it indicates that the motion track is a full circle.

In the radius interpolation: D100 speed, D102 is the X-axis target address, D104 is the Y-axis target address, and D106 is the radius length. Y0 and Y1 respectively pulse the X-axis and Y-axis.

7.2.2 Continuous interpolation function

M8436 is the flag for the normal interpolation mode and continuous interpolation mode.

M8436=0: regular interpolation mode; M8436=1: continuous interpolation mode;

In CoolMay 3G PLC 26236 and higher version, continuous interpolation motion uses DPLSR for

pulse output.

Operand Description: All use 32-bit registers. S1. indicates the pulse frequency, that is, the speed of the interpolation motion. S2. indicates the X-axis target address. S2.+2 indicates the Y-axis target address.

In the center mode: S2.+4 and S2.+6 indicates the Center coordinates.

In radius mode: S2.+4 indicates the radius length, and S2.+6 ignores and unused.

S2.+4 positive value: the path is a small circle; S2.+4 negative value: the path is a big circle. S2.+8 is the control register.

D.: Specify the Y number with pulse output (only Y0 supported), and the default Y1 is another axis.

In continuous interpolation mode, M8432~M8435 are determined by the 5thparameter (ie S.+10). The function description of each bit of the 32-bit register S2.+8 is as follows:

When S2.+8 is used, it is expressed in hexadecimal. The bit values of each group are as below shown :

PS: When using linear mode interpolation, b7~b4 is ignored and can be set to any value from 2~F.

S1. and S2. may be set discontinuous. For example, S1.=D100, S2.=D120. S2. Must be consecutive with the next four 32-bit registers. For example, it must be set to D102,

D104, D106, D108, D110.

For example: draw a line and two arcs, as shown:

M8426=1: CAN is in multi-machine mode, there is no master-slave division, and it can

transmit up to 8 bytes of data.

M8426=0: CAN is the master-slave mode. There must be one master on the bus line,

which is similar to the MODBUS function.

M8427: =0 means setting as CAN2.OB extension frame. =1 means setting as CAN2.OA

standard frame.

M8428: Set as ON while right response of MODBUS communication and needs manual reset. M8429: Communication times out. D8420：Communication parameters. D8420: The 0th to 9th bits are CAN baud rate, 1K~1023K. The default is 500.

Supported baud rate:5 10 15 20 25 40 50 62 80 100 125 200 250 400 500 666 800 1000.

D8421: Communication protocol and description of master-slave station.

CX3G/FX3GC PLC Programming manual

1) Support RS2 instruction

2) Support WR3A,RD3A instruction.

3) Support ADPRW instruction

RS2 command: Setting as D8421=H10, which means RS protocol. RD3A, WR3A, ADPRW command: D8421=H1 is master station, D8421=H10 is slave station. D8126: When using the ADPRW instruction, set the D8126 to 2 when using CAN. (lower than

26232 version)

D8397: When using the ADPRW instruction, set the D8397 to 2 when using CAN. (versions

26232 and above)

D8426: Interval period. Default as 12 times. D8429: Time-out period. D8434: Slave station number. D8440: Save the local ID number (slave station number). D8442: When multiplexed, save the slave ID number (the slave what data is read).

RS2 finial parameter =0: serial port 2;

=1: serial port 3; =2: CAN

When RS2 support CAN, multiple channels can communicate with each other, ID(read 29

bit )=D8442；ID（write 29 bit）=D8440,at most 8 length.

29 digits indicate that the first three are useless. Multi-channel interconnection example:

LD M8000 RS2 D600 K8 D800 K8 K2 LD M8002 MOV H10 D8421

LDI M8422 ANI M8424 SET M8422

For specific operation explanation, please refer to WR3A and RD3A instructions of serial port 2

or serial port 3

S.-1 address value must be set to 2. (=0: serial port 2; =1: serial port 3; =2: CAN)

( Set D8126=2 Corresponds to optional CAN port)

For example, CAN port program of expansion board LD M8002 MOV H1 D8421：CAN port of this PLC is the master station LD M8000 MOV K2 D8126 LD M8 ADPRW H1 H2 H2000 K16 M100 It means that the CAN port of the PLC communicates with the CAN port of the slave PLC, and

reads 16-bit S0~S15 of the slave PLC to the M100~M115 of the master PLC.

The default state is compatible with Mitsubishi original programs. The Mitsubishi PLC only has one port to support the ADPRW instruction, depends on D8401 (in prior) and D8421. All three ports of Coolmay PLC support the ADPRW instruction.

Automatically detect the network after power-on. M8193=1 when there is a network chip, network preparation.

Special relays, registers and registers that IP addresses used are as below.

M8193：=1 Represents that there is a network chip, network preparation

M8197：=1 Write network address, automatic reset (Not support 26231 version, you can write the above parameters and then restart).

M8062：=1 Represents MODBUS timeout, MODBUS_TCP is used.

M8063：=1 Represents IP address is conflict.
