Special instructions for ordering:
1) If the model provides digital input, the DIN default type: wet contact, optional: dry contact. The input type
cannot be changed after manufacturer delivered. The DIN1 default is high-speed count mode; it can be
changed to low-speed count mode by open the shell and change the internal jumper. If require dry contact
input, please note when ordering, if DIN1 require high-speed pulse count mode then must be wet contact.
2) If the model provides digital output, the DO type is SINK, DO1 supports high-speed pulse output; DO2 can be
used to control the direction of the stepper motor. Also can connect external relay if need.
3) The model number: M240T, M340T support thermal resistance temperature transmitter default type: PT100,
optional: PT1000, if you need PT1000 type of thermal resistance, please note when ordering.
4) All models support the register mapping, can extend I/O or meters via Modbus RTU protocol.
5) Each model’s I/O port qty is referred to the above table only. As MXXT series use same housing, those I/O
port hardware terminal blocks on the device which not described in the table is not valid.

RS485 Settings
If the slave is only provides RS-232 interface, please use the RS-232/RS-485 converter connected to the 485
network. It is strongly recommended to use the isolated RS485 converter to improve system reliability. In a BUS, all
of the equipments ‘data A + should be connected together, and data B- should be connected together, cannot be
reversed, RS485 signal to the GND terminal should be shorted together, and connect to the module’s ground only.
RS-485 network generally allows up to 32 nodes in parallel devices, more than 32 systems need to use RS485
repeater to expand. RS-485 communication line should be STP(shielded twisted pair), the shield should be
single-ended ground; RS485 communication distance can be up to 1200 meters, when a bus connected to a lot of
RS485 devices, or use high baud rate higher communication distance Will be correspondingly shortened
accordingly, then you can use RS485 repeater to expand. RS-485 network has a variety of topology, the general use
of linear connection, that is, start from near to far, connecting devices to the master one by one. In the far end can
be connected to 120 ~ 300Ω / 0.25 watts of terminal matching resistance (depending on the communication
quality to determine).
Mode Selection : Master or Slave optional.
Baud rate : 2400,4800,9600,14400,19200,38400,57600,115200,128000 optional.
Data Bit: 7,8 bit.
Parity Bit: None, Even and Odd optional.
Stop Bit: 0.5Bit,1Bit,1.5Bit,2Bit optional.
Over time: Wait for the command reply time, the next command will be sent after timeout, default 200ms
Interval: Polling time, each command sending interval time, default is 50ms, please increase the time
appropriately when there are too many slaves.
Retry counts: command reply timeout retry times, default is 3 times.
Mapping Registers--Read Coil & Registers: Mapping registers between the slaves and module
After configuration, the module will Read the Modbus slaves automatically by the corresponding read coil and
register function codes according to the mapped registers.
Slave address : slave device ID,range 1~247.

Mapped Addr(100-399) : Stand for mapping the slave start register data to the device start mapping address,
Can be set 100-399,The mapping addresses of the transit Bit and 16-bit registers are
separate, each occupying 300. The mapping addresses of the same type must not be the
same, and the mapping addresses for reading and writing cannot be the same.
Collection Target : Optional RS485, ports 1 ~ 5, corresponding to TCP slaves 1 ~ 5 respectively.
Add : After editing a slave information, click” Add” to map the register address of the cluster device to the
mapping storage area of this device.
Del : Select an edited slave information, click this item to delete the corresponding slave information.
Mapping Registers--Write Coil & Registers: Mapping registers between the slave and module
After configuration, the module will write the Modbus slaves automatically by the corresponding Function codes
according to the mapped registers.

Function code : Sets the type of action host to slave.including 05/15 write holding coil and 06/16 write holding
register, where the value of the holding coil is automatically allocated to the mapping storage area
of the relay bit register, and the value of the holding register is automatically allocated In the
mapped memory area of the transit 16-bit register.
Slave Start addr : The starting register address for slave data writing.
Number of registers : How many register need to write.
Mapped Addr(100-399) : Stand for mapping the slave start register data to the device start mapping address,
Can be set 100-399,The mapping addresses of the transit Bit and 16-bit registers are

Note: After setting, please click "System Settings"-"Loading data" option to save the set parameters.
7.6 Register list
The mapped register list in the Web page is only readable and cannot be written. It is used to display the current
value of the register in the mapping area, which is convenient for user debugging. There are 300 registers for the
Bit Type register, used to store one bit can represent the state of the data, e.g.: input coil, holding coil value. 300
registers for the 16-bit type register, used to store input register and holding register data. 300 BIT-bit
registers(Boolean) and 300 16-bit register mapping areas are provided. (those 300 register can be 16-bit,32-bit or
64-bit,32-bit takes 2 16-bit address,64-bit takes 4 16-bit address)The module will automatically assign and stored
them according to the coil or register set in Mapping Registers page.
