8 slots; requires 1 AnS series PLC power modules;
Used to install large AnS series PLC module.
Base plate of AnS series PLC.
QA1S series PLC 8 slot main substrate.
AnS series of modules can be installed. 3C-2V/5C-2V coaxial cable between double loop PC (control station / common station) / remote I/O network (remote master station) A172SHCPU.
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 A172SHCPU A172SHCPU
This phenomenon is called the I/O delay time effect.
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.
So, sometimes also known as the order control A172SHCPU.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three. Type of input: DC source.
Input points: 16 points.
Input voltage: DC24.
Input current: 7mA.
Connection mode: terminal row.
Common common point: 16.
Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit.
The function module is used to represent the function of the module,
Different function modules have different functions.
Functional module figure programming language features: functional block diagram programming language is characterized by a functional module for the unit,
Analysis and understanding of the contrrol scheme is simple and easy: function module is to use graphical form of expression,
Intuitive, for a digital logic circuit based on the design of the staff is very easy to master the programming;
Control system with complex scale and coomplex control logic,
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced A172SHCPU A172SHCPU.
