Data format: ASCII.
Data bits: 7.
A1SJ71UC24-R2-S2 and A1SJ71UC24-R4-S2 allow the Ans series PLC to be connected to the MODBUS network,
As the network from the station, and in accordance with the instructions of the main station of the CPU Ans user storage area for data reading / writing.
In addition to supporting the MODBUS protocol, these components also support the standard dedicated communication protocol for A1SJ71UC24 components AJ35T-M04B-K datasheet PDF catalog AJ35T-M04B-K PDF datasheet AJ35T-M04B-K
This feature makes the main station of the data acquisition and control with more flexibility.
Support MODBUS slave station protocol.
Supports 1 to 21 function code.
Two transmission modes: RTU or ASCII. Fiber optic cable / twisted pair cable.
Single bus.
Control unit AJ35T-M04B-K datasheet PDF catalog AJ35T-M04B-K PDF datasheet.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system AJ35T-M04B-K datasheet PDF catalog AJ35T-M04B-K PDF datasheet.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc.. 3C-2V/5C-2V coaxial cable.
Single bus.
PC inter network (management station / common station) / remote I/O network (remote control station).
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps.
Design PLC peripheral hardware circuit.
Draw the electriical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc AJ35T-M04B-K datasheet PDF catalog AJ35T-M04B-K PDF datasheet. .
The electrical schematic diagram of the system compoosed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram AJ35T-M04B-K datasheet PDF catalog AJ35T-M04B-K PDF datasheet.
So far the system''s hardware electrical circuit has been determined.
