STN color / monochrome LCD man-machine interface to replace the backlight.
Applicable models: A95_GOT- (Q) SBD/ (Q) LBD (-M3) (). Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Optical data communication line A58B PDF datasheet.
User program storage capacity: it is a measure of how much the user application can store the number of indicators A58B
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4 A58B PDF datasheet.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance A58B PDF datasheet. Output type: transistor output, source.
Output points: 16 points.
OFF leakage current: 0.1mA.
Output protection function.
Rated load voltage / current: DC12V/DC24V/0.1A.

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 conveniennt, the expression methods of the statement and the types of statements are simplified A58B PDF catalog.
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 A58B PDF catalog. Poor visibility and operability.
