2N-20MT-CFB PLC Control Board Programmable Logic Controller Compatible With 2N 1N 20MT (B)

2N-20MT-CFB PLC Control Board Programmable Logic Controller Compatible With 2N 1N 20MT (B)

Introduction:
This PLC is suitable for GX Developer and GX Works2 software for programming, reading, downloading, testing, diagnosis, and monitoring programs.

1. Basic Functions:
1) Support watchdog function-compatible with the original;
2) Support external interrupt function-compatible with the original; support pulse collection, support X0-X5 (6 ways in total);
3) After the password is set to 12345678, the program cannot be read, but the device data can be read, and the password modification program will be cleared;
4) Except for the D register, the range of components is compatible with the original ones;
5) Support data retention after power failure (all power failures are FLASH retention, and the data will be checked when power is on);
6) Enter and check the downloaded ladder diagram program;
7) When the program is running in the PLC, the program instructions and component range will be checked, and if there is a problem, the corresponding fault will be reported;
8) When the operation switch is pulled to RUN, the RUN running light flashes; when it is pulled to STOP, the RUN running light is off;
9) When a minor fault is detected during operation, the ERR light will flash; when a serious fault is found, the ERR light will be on;
10) Support constant scan mode: D8039-constant scan time, M8039-constant scan mode.

2. Optional Functions:
1) Support PLSY and PLSR to send pulse (support positioning instruction): support Y0, Y1, Y2 and Y3. Y0 and Y1 send up to 200Khz, Y2 and Y3 send up to 100Khz (transistor output type, the specific PLC configuration determines the number of high-speed output channels);
2) Support RTC real-time clock function-compatible with the original (when the password is 12345678, the programming software cannot modify the clock data);
3) Support encoder input function, support up to two AB phase input. Can customize response 60KHz (and AB phase input can choose 2 times frequency and 4 times frequency-the same encoder can get 2~4 times the accuracy), support SPD instruction (X0~X5: 6 channels in total), high-speed counter-compatible with the original;
4) Support external interrupt function-compatible with the original; support pulse collection, support a total of 6 channels X0-X5;
5) Support two communication ports, both of which support the programming port protocol, which can be used when it is used (programming software can be used to communicate with the two serial ports at the same time). The first channel only supports the programming port protocol; the second channel supports the programming port protocol and for MODBUS-RTU protocol, can be switched by D8120 in the program; the baud rate of serial port 1 is 9600 or 19200, and the baud rate of serial port 2 is set in D8120.

Component Range:


Supported Instructions:
1) Basic instructions (all support): LD LDI LDP LDF AND ANI ANDP ANDF ANDB OR ORI ORP ORF ORB MPS MRD MPP MC MCR INV PLS PLF OUT SET RST NOP END
2) Step instruction: STL (maximum support 8 branches) RET
3) Application instructions: program flow, transmission and comparison, four logical operations, circular displacement, data processing, high-speed processing, convenient instructions, peripheral instruction I/O, peripheral equipment SER, floating point numbers, positioning, clock operations, peripheral equipment, contacts compare

Attention:
1) Support 32-bit instructions, support P instruction;
2) When an unsupported command is used, a 6506 fault will be detected;
3) The yellow one is the FX2N command, which is not supported by FX1N.

Package Included:
- 1 x PLC Board
