NSD servo system.
A73CPU (P21/R21) -S3 dedicated.
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 A956GOT-LBD User's Manual.
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 A956GOT-LBD
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 A956GOT-LBD 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 A956GOT-LBD 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. Input type: DC input, positive common end.
Input points: 8 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/5mA.
Output form: transistor output, leakage type.
Output points: 8 points.
OFF leakage current: 0.25mA.
Output protection function.
Rated load voltage / current: DC24V/0.5A.
External connection: 4 wire.
Fast connector type.
Simple wiring through quick connector.
Can be installed along the 6 direction.
MITSUBISHI PLC program siimulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of thee program A956GOT-LBD Manual A956GOT-LBD Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
