SI/QSI/H-PCF/ wide H-PCF optical cable double loop PC (control station / common station) / remote I/O network (remote master station).
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order A171SHCPU PDF A171SHCPU
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
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 A171SHCPU PDF.
The response time of PLC is the interval between the time of the change of the external output signal of 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 use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on A171SHCPU PDF.
This phenomenon is called the I/O delay time effect. I/O slots: 8 slots.
Could you install the power module.
Outline dimension: 420*130.
There are two types of extended floor,
A power module can be inserted, and the other one is not.
The choicee of any type of substrate depends on the total DC5V current consumption and the power supply on the CPU main substrate A171SHCPU datasheet.
If the total demand is less than the power output, no additional power supply,
Then you can choose a more ecconomical expansion board A171SHCPU datasheet.
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection.
