ST语言是指,关于开放/控制中的逻辑记述方式所制定的国际标准IEC61131-3 中定义的语言。
● 通过部件化可以提高设计效率。
在ST 语言中通过预先执行部件化操作将常用的处理定义为功能块(FB),可以调用各程序的必要部分。由此,在提高了程序开发效率的同时,也减少了程序错误,提高了程序的质量。
● 可以在系统运行过程中更改程序(运行中写入)。
可以在不停运可编程控制器CPU的状况下,对正在执行的程序进行部分变更。
● 可以与其它语言程序结合使用。
由于也支持除ST语言以外的其它语言,因此可以使用适用于处理对象的语言以提高编程效率。
例如,通过创建梯形图程序进行顺序控制,通过编制ST 语言进行运算处理。由于可支持多种语言,可对较大范围内的用途执行最佳控制。
● 配备了丰富的函数群。
在ST程序中,配备了对应于MELSEC-Q系列用的各种通用指令的MELSEC函数、IEC61131-3中定义的IEC 函数。
programming interface to embed external
In Windows operating system applications, it is suitable for implementing user
Communicate with non-standard OPC, ie DMS-API software package.
Project database
All configured signals, variables and process points are in Freelance
800F system’s public database for management.
● List of all variables (input, output, internal variables)
● Process point list (function block)
●Graphics
●Program
Because the database is system-wide. The data only needs to enter a
times, to avoid possible errors caused by multiple configurations.
Project database files can be easily archived or backed up.
When programmed by the user, a list of variables and labels is automatically created.
Moreover, both variables and process points can be opened and closed directly in FBD or IL
Revise.
List other features include:
Project-wide modification of names, comments, data or module types
●Search and display based on specific criteria
● Cross reference can be used in systems that use a large number of variables or process points
Programs and drawings to quickly find the desired variable or process point within the scope

ABB is the world’s largest in measurement and process automation
One of the equipment and system suppliers.
An important factor in maintaining this market position is the quality of our products
quantity, and quality from manufacture all the way to service. ABB automation early
In 1990, it obtained the DQS certificate based on ISO9001 certification,
EQnet quality based on ISO 9000/EN 29000 was subsequently achieved
Certification.
However, the Freelance 800F is more than technical excellence, I
We have also spent a lot of effort in proper planning, installation and revision too
This makes engineering design and maintenance faster, more
