I/O slots: 5 slots.
Can you install the power module.
Outline dimension: 260*130.
There are two types of extended floor,
A power module can be inserted, and the other one is not.
The choice of any type of substrate depends on the total DC5V current consumption and the power supply on the CPU main substrate AC30R4.
If the total demand is less than the power output, no additional power supply,
Then you can choose a more economical expansion board AC30R4
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection. I/O slots: 5 slots.
Outline dimension: 325*130.
CPU basic board can be plugged into 1 power modules,
1 CPU components and a maximum of 2, 3, 5, or 8 single slot size special function components and I/O components are respectively inserted and arranged AC30R4.
Expansion ports are arranged on both sides of the base plate,
For connecting the expansion board for.
Up to 3 extension substrates. I/O points: 1024.
Processing speed: sec/ 0.15u step.
Memory capacity: 256K bytes.
Program capacity: 30K step.
PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments AC30R4.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through the digital, analog input and output, control of various types of machinery or production process.
Programmable controller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions. Capable of continuous thermocouple or platinum temperature measurement.
In addition, the temperature measurement range can be set with the use of the temperature.
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 oof the PLC and 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 AC30R4 AC30R4.
This phenomenon is called the I/O delay time effect.
