MITSUBISHI AX31 User's Manual PDF

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 AX31 PDF.
In addition to supporting the MODBUS protocol, these components also support the standard dedicated communication protocol for A1SJ71UC24 components AX31
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 AX31 PDF.
Two transmission modes: RTU or ASCII. 8 slots.
Power supply unit.
QnA series unit installation.
High speed access.
I/O points is an importantt indicator of PLC AX31 Manual.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest AX31 PDF.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30% MITSUBISHI User's Manual.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program MITSUBISHI User's Manual.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
Wheen the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load MITSSUBISHI User's Manual AX31 Manual AX31 User's Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
