Input voltage range: AC100-120V/200-240V.
Output voltage: DC-15/15V.
Output current: A616DAV 0.7A/1.2A, for A616DAI.
I/O slot installation.
Is the analog output unit (A616DAV, A616DAI) dedicated power supply.
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 A1SJ61BT11.
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 A1SJ61BT11.
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% A1SJ61BT11.
The following describes the centralized control system I/O points of the estimate. DC input points: 8 points.
Input voltage and current: 7mA, DC24V.
Response time: 10ms.
8 point /1 a public side.
Positive / negative sharing.
Output points: 8 points.
Output voltage and current: DC24V/AC240V, 2A/1 point, 5A/1 common end MITSUBISHI A1SJ61BT11.
Response time: 12ms.
8 point /1 a public side.
Output form: relay output.
34 point terminal station.
Number of stations: 2 stops.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program MITSUBISHI A1SJ61BT11.
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 detection, fault diagnosis and display and other procedures MITSUBISHI A1SJ61BT11.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy to guarantee the timeliness.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
Three remote components can be connected to the CC-LINK system.
Remote I/O: refers to the field components that require only ON/OFF control,
Such as digital I/O or pneumatic valve, etc..
In this type of communication can only be carried out in the bit data.
Remote components: the field components that require processing of register data,
For example analog I/O and counter, etc..
In this type of component, in addition to the bit data can be carried out in the register data communication.
Intelligent remote: this type of element refers to the actions that allow the master station or other station to access,
To collect data and control the local PLC station,
GOTS and programmer interface unit are of this type.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work.
