Data format: RTU.
Data bits: 8.
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 A953GOT-LBD-M3 User's Manual A953GOT-LBD-M3
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. Pulse input: DC input.
Default input: DC input.
Count range: 0~16777215 A953GOT-LBD-M3 User's Manual.
Number of stations: 4 stops.
Station type: remote equipment station.
Configuration of master / local station,
In addition to the other site network with different CC-Link in addition to the main station and the remote station configuration can also be the main station and the local station configuration.
A local PLC can communicate with the master station PLC and other remote workstations A953GOT-LBD-M3 User's Manual. RS-232 2 channel.
Transfer speed: 0.3-19.2kbps.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU MITSUBISHI A953GOT-LBD-M3 Manual.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive MITSUBISHI A953GOT-LBD-M3 Manual.
Semiconductor circuit with memory function.
System program memory and user memory.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation MITSUBISHI A953GOT-LBD-M3 Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. For A6TBXY36/A6TBXY54/A6TBX70E (common cathode; drain type) long 3m.Twisted pair / rubber insulated cable.
Single bus.
LINK MELSEC-I/O (control unit).
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 MITTSUBISHI 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 A953GOT-LBD-M3 Hardware.
The main contents of the initialization program arre: 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 A953GOT-LBD-M3 User's Manual. .
