32 point connector for compressed flat cable (37 pin D-Sub connector).8 channels.
Input: DC-10 ~ 10V, DC4 ~ 20mA.
Output (resolution): -2000 ~ 2000.
Transform speed: 2.5ms/1 channel.
38 point terminal station.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register A2NCPUR21-S1 Programming Manual .
And then combine the data and the program with CPU A2NCPUR21-S1
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive A2NCPUR21-S1 Programming Manual .
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light A2NCPUR21-S1 Programming Manual .
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process. DC input points: 8 points.
Input voltage and current: 7mA, DC24V.
Response time: 10ms.
8 point /1 a public side.
Positive / negative sharing.
24 point terminal station.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc..
MITSUBISHI PLC program simmulation 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 A2NCPUR21-S1 Manual A2NCPUR21-S1 Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
