A3VTS using the basic unit.
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 disconnected from the load MITSUBISHI A953GOT-SBD-M3-H User's Manual A953GOT-SBD-M3-H
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
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 A953GOT-SBD-M3-H User's Manual.
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 MITSUBISHI A953GOT-SBD-M3-H User's Manual.
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%.
The following describes the centralized control system I/O points of the estimate. QnA/ACPU bus connection.
2 joint.
Applicable models: A985 (-V) /975/970/960/956 (W) GOT. Screw, 2 piece type terminal.
Current output module.
Number of channels: 4 channels.
Number of stations: 2 stops.
Station type: remote equipment station.
High speed data transfer of up to 10Mbps;
The development of CC-LINK is not only to meet the control of high speed remote I/O,
But also to meet the high speed of the field of information control A953GOT-SBD-M3-H Manual.
In order to achieve this goal, the transmission speed of CC-LINK is compared with that of the previous live netwwork system to add 40 to 10Mbps A953GOT-SBD-M3-H Manual.
Such a high speed can not affect the speed of the machine control while allowing a large number of data communication.
