介绍 Modicon M258 Logic Controller 中提供的脉宽调制输出和频率发生器功能。
本文档还介绍 M258 PWM/FreqGen 库的数据类型和功能。
·对 M258 有着透彻理解,包括其设计、功能和在控制系统中的实现。
·熟练使用下列 IEC 61131-3 PLC 编程语言:
·功能块图 (FBD)
·梯形图 (LD)
·结构化文本 (ST)
·指令列表 (IL)
·顺序功能图 (SFC)介绍 Modicon M258 Logic Controller 中提供的系统功能和变量。M258 PLCSystem 库包含的功能和变量可用于获取信息并向控制器系统发送命令
mode. Modular pluggable input/output modules
Blocks are freely selected and used according to the type and number of system process signals.
AC800F controller connects remote I/O or field device via fieldbus
ready.
system communication
Communication between operator level and process control level using TCP/IP
Protocol system bus (based on Ethernet), you can choose different
transmission medium such as AUI, twisted pair, fiber optic or coaxial cable.
Freelance OPC server for connecting to higher-level operators
station (800xA) or other OPC client. Freelance Control System
Real-time process values ??and alarms in the system can be accessed via OPC.
We also provide a C language 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
