1 Summary

1.1 COOLMAY MX2N PLC main advantage

◆ Could use GX Developer and GX Works2 software to program,read,download,
verify, diagnose,monitor and process sequence.

◆ Could customize 12 channels AD and 2 channels DA,in 12bit precision,use RD3A
to read AD data and WRA3 to output DA data (can set upper and lower limit ranges.)

◆ Support optional one RS485 or RS232 COM Port,support Programming port
protocol and MODBUS-RTU master-slave protocol.It can be switched in the program
through D8120,support communication through RS485 networking and inverter etc.

◆ Support RTC function,when password is 12345678,the programming software
can't modify clock data.

◆ High Speed counter input conventional 6 channels single-phase counting (X0-X5)
or 2 channels AB phase counting (X0-X1/X3-X4）10KHz, it can be customized 6
channels single-phase counting at most (4 channels 60KHz,2channels 60KHz).

◆ High speed pulse output conventional 4 channels 20KHz Y0/Y1/Y2/Y3, it can be
customized 4 channels Y0/Y1 200KHz,Y2/Y3 100KHz.

◆ Support Watch dogs function-compatible with Mitsubishi FX2N.

◆ Support external interrupt function-compatible with the original,support pulse

capture function,support 6 channels X0-X5.

◆ Support super password: When password is 12345678,the program can't read
except the device data. When password is changed,the program will be cleaned. You
can also open the PLC program to disable the read mode on setup software (Once
open, no matter what the password is,the program can't be read.)

◆ Support Power-down data protection (All power-down is Kept by FLASH,data
will be checked when power-on.)

◆ Check the downloaded ladder program

◆ When the program run in the PLC,it will check the program instructions and the

components range,corresponding problem will be reported when being detected.

◆ Run light flashes when switch turns to "RUN", run light goes out when to "STOP".

◆ During running. If check slight fault,the ERR light flashes. If serious fault,ERR

light is on always.

◆ Support constant scan mode: D8039-Constant scan time,M8039-Constant scan
mode.

◆ Support CAN networking communication function. Support 32 slaves at
most,master-slaves share 32 registers at most,communication baud rate could be set.

◆ Optional High speed pulse output function, PWM support the highest frequency
900KHz,duty ratio is -100%.

◆ Support function of thermocouple temperature measuring: automatic cold junction
compensation,could connect 2 channels K/E/J thermocouple at most,could measure
negative temperature.

◆ Support function of program limit : could select clock date limit,power-up
