Cable length: 30 meters.
For QCPU and GOT (need A9GT-QCNB) connection.
For the connection between GOT and GOT. 8 channels.
3 wire platinum measuring antibodies (Pt100, JPt100) AJ71E71N-B2 PDF.
Transform speed: 40ms/1 channel.
38 point terminal station.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference AJ71E71N-B2 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 AJ71E71N-B2 PDF.
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 AJ71E71N-B2 PDF.
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 MITSUBISHI User's Manual.
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 MITSUBISHI User's Manual.
And then combine the data and the program with CPU.
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 MITSUBISHI User's Manual AJ71E71N-B2 Manual. QnA/ACPU bus connection.
1 joint.
Applicable models: A985 (-V) /975/970/960/956 (W) GOT. Temperature sensor: PT100, 3 wire system.
The A1S62RD3 and A1S62RD4 temperature sensor input modules allow the platinum resistance temperature sensing element to be directly connected to the PLC,
This component converts a signal from a temperature measuring element to a numeric value that represents a temperature measurement value,
This temperature value can be used for the control process.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC annd the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the usse of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on AJ71E71N-B2 Manual AJ71E71N-B2 User's Manual.
This phenomenon is called the I/O delay time effect.
