A: A phase input B: B phase input
R: External reset input S: External start input
● Input X000~X007, as shown in the above table, corresponding to each high-speed
counter number. Inputs X000~X007 cannot be used repeatedly by high-speed
counters. They can be used for general input when the input terminals are not used as
high-speed counters.
MX2N series HMI PLC all in one programming manual
24
● The input X000~X007 cannot be reused. For example, once C251 is used, X000
and X001 are occupied, so C235, C236, C241, C244, C246, C247, C249, C252, C254
and interrupt input pointers *I00, *I01 and corresponding input SPD instructions
cannot be used.
6.2 High speed count input instructions
1) Maximum response frequency of C251 C252 C254 (AB phase): 60KHz;
2) Maximum response frequency of C253 C255 (AB phase): 60KHz;
3) Maximum response frequency of C235 C241 C244 C238 (single phase): 60KHz;
4) Other high-speed counter’s highest response frequency: 10KHz;
5) High speed counter of the AB phase can be set to 2 times and 4 times frequency
(setting is valid only for OUT drive same cycle):
** When M8196-ON, C251 C252 C254 count pulse is 2 times frequency;
**When M8197-ON, the C253 C255 count pulse is 2 times frequency;
** When M8198-ON, C251 C252 C254 count pulse is 4 times frequency;
**When M8199-ON, C253 C255 count pulse is 4 times frequency;
For example: If you use an AB phase encoder, it is 1024 pulse inputs in one turn. If
not set the frequency multiplier, then adjust the counter count 1024 (the original
FX1N does not support frequency multiplier, but the FX3U can set 4 times frequency),
If you set 2 times the frequency, then turn the counter to count 2048; if you set 4
times, then turn the counter to count 4096.
Usage instruction:
No Multiplier
2 Times Frequency
4 Times Frequency
** Other usage are consistent with the original FX1N, see the FX programming manual for
details;
** If high-speed input function is not selected, Then SPD, external interrupt, and C235~C255
high-speed counter cannot be used normally.

9 MX2N-70HB Optional com port instructions
9.1 Function Description
1) MX2N-70HB supports the optional 1 RS485 communication port, but can not coexist with
its own 232 port.
2) Support exchange between Mitsubishi programming protocol and MODBUS-RTU
protocol. (When PLC stops, it will be back to Mitsubishi programming protocol; When PLC
start, the protocol depends on D8120.)
3) Communication data of optional communication port is set in the D8120 and it will take
effect after PLC runs (the modification could be made until the STOP-RUN is valid again
when the PLC is in effect, the D8120 is reset to 0 when the PLC is in STOP), and the
MODBUS-RTU slave station number is set in the D8121 ( Range 1~255).
4) Use FROM to read slave data when using MODBUS-RTU master, to write slave data
(supports broadcast sending function)
5) Set the optional communication port to MODBUS-RTU protocol. the baud rate of slave is
9600 . as follows:

Note: 1.M8121, M8122, M8123, M8124 are only for internal use. Don’t write to the
MODBUS-RTU master when using it.
2.When D8129 receives the timeout, please set according to the actual setting. When
the setting time is too long, if there is a slave communication failure, the waiting time for
re-communication (namely D8129) will be very long.
9.3 D8120 Parameter and Function setting
D8120 Setting function diagram as below: (D8120 communication parameter selection
register)
*1：The start and end characters can be set by user
MX2N series HMI PLC all in one programming manual
29
*2：D8121 is MODBUS-RTU slave station number setting
*3：When the data bit is in 7 bit,the parity can’t be selected---No checking. (6038 failure).
*Mitsubishi Programming port protocol：Data length is 7，stop bit is 1，Parity EVEN is fixed，
the rate can be set；
*MODBUS-RTU protocol：data length, stop bit, parity, rate can be set;
*RS instruction： Data length, stop bit, parity, rate, start character, and end character can all be
set.
9.4Modbus-RTU Master station instructions
Master read slave data usage instruction
* Transfer the data of register from address 0 of 1ststation to D0
M1--low 8 bits indicate the slave address, high 8 bits indicate the sent instruction;
Such as: H301-command 03 (read register instruction), slave address 01; if the high 8 bit is 0,
then the command is default as 03;
M2--slave element address; (Slave address of MX2N series PLC refers to slave element
address table);
D - master station data register, this register holds the data which read from the slave station;
N -- read data length (1~64);
Master write slave data usage instruction
* Write the data of D0 to the register with the 1stslave in address 0
M1--The lower 8 bits indicate the slave address ,the high 8 bits indicate the sent instruction;
Such as: H601-command 06 (read register instruction), slave address 01; if the high 8 bit is 0,
the command defaults is 06;
M2--slave component address; (Slave address of MX2N series PLC refers to slave element
address table);
If the address is set to 0, it means that data is written to all slaves;
D -- the master station data register, which holds the data to be written to the slave;
N -- write data length;
When using commands 05 (write bit) and 06 (write register),act as 1 regardless of the
length is set.
When using H10 (K16) to write multi-bit registers, the data length (1~64);

are executed at the same time, the system will communicate in turns. If the communication is
overtime, M8129 turns ON and reports 6306 fault and exits this communication, and records
this overtime station number in the D8122 register,execute the next communication
instructions;
2. The FROM/TO instruction cannot be used with the RS instruction in the program at
the same time, reporting 6609 failure;
3. The maximum data length of the FROM/TO instruction: bit (1~64), register (1~64);
4. The communication parameters of the master station and the slave station must be set
same to communicate, such as data length, parity, stop bit, and rate;
5. When using the 05 command to set the slave station component, such as: TO H501
K4000 D0 K1—Set the M0 state of slave No. 1. If D0 is equal to 0, slave M0 is OFF; when
D0 is non-zero, slave M0 is ON;
6. When using the TO command, you can send instructions to all slaves, and only need
to set the slave address to 0.
For example, TO H600 K0 D0 K3: Write D0, D1, D2 of master station to register
addresses 0, 1, 2 of all slaves.
D8129—Communication timeout setting, default 500ms; setting technique, set D8129
larger,when writing program communication is normal, run a period of time, monitor the
value of D8124, D8129 equals D8124 plus 3 (only for reference );
Note: 1) The function needs to be enabled in IO setting and activation software,
otherwise it will report 6506 fault (unsupported instruction) when using FROM/TO
instruction;
