QnA/ACPU bus connection.
1 joint.
Applicable model: A956WGOT. 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 AJ65VBTCU-68ADIN PDF.
If the total demand is less than the power output, no additional power supply,
Then you can choose a more economical expansion board
AJ65VBTCU-68ADIN
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection. Input voltage range: AC100-120V/200-240V.
Output voltage: DC-15/15V.
Output current: A616DAV 0 AJ65VBTCU-68ADIN PDF. 7A/1.2A, for A616DAI.
I/O slot installation.
Is the analog output unit (A616DAV, A616DAI) dedicated power supply.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point AJ65VBTCU-68ADIN PDF.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate. Output type: transistor drain.
Output points: 16 points.
Load voltage: DC12/24.
Load current: 0.1A.
Connection mode: terminal row.
Common public end points: 8.
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language. In large and medium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system.
Mainly used for other programming languages more difficult to achieve the user program.
The structured text programming language uses the computer description method to describe the various kinds of relations between the various variables in the system,
Complete the required function or operation.
Most PLC manufacturers use structured text programming language similar to BASIC language, PASCAL language or C language and other advanced languages,
But in order to be convenient, the exppression methods of the statement and the types of statements are simplified AJ65VBTCU-68ADIN datasheet.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Needd to have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers AJ65VBTCU-68ADIN datasheet. Poor visibility and operability.
