For A6TBXE/A6TBY36E/A6TBX54E/A6TBY54E/A6TBX70E (common cathode; source) long 5m.Interface: RS232C.
Transmission distance: 15 meters.
A1SJ71UC24-R2/R4/PR computer communication components can communicate with PLC, such as computers and other external intelligent devices, and the components are as follows:
Full / half duplex transmission A1NCPU Common Instructions Manual A1NCPU Programming Manual .
4 special communication protocols A1NCPU
No protocol and bidirectional mode.
Protocol selection switch function.
The optional baud rate, the highest 19.2K.
Since the echo diagnostic test. Memory card interface (AD59-MEF), parallel interface.
On-line debugging is the process that will through the simulation debugging to further carry on the on-line unification to adjust A1NCPU Common Instructions Manual A1NCPU Programming Manual .
On-line debugging process should be step by step,
From MITSUBISHI PLC only connected to the input device, and then connect the output device, and then connect to the actual load and so on and so on step by step.
If you do not meet the requirements, the hardware and procedures for adjustment.
Usually only need to modify the part of the program can be. 8 slots.
Power supply unit.
QnA series unit installation A1NCPU Common Instructions Manual A1NCPU Programming Manual .
High speed access.
CE logo fit.
I/O points is an important indicator of PLC.
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.
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%.
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.
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.
When 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 discoonnected from the load A1NCPU Common Instructions Manual A1NCPU Programming Manual A1NCPU Common Instructions Manual A1NCPU Programming Manual .
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
