通过 PID Professional 软件包，可以在 TIA Portal 中使用 Modular PID Control 和 Standard PID Control 的成熟控制器解决方案。此软件包可在实现简单到高度复杂的 PID 控制器时使用。通过将提供的标准函数块互连，可实现几乎任何控制结构。

Modular PID Control 较适合中端和高端控制应用和过程组态。在需要较低的存储器利用率、较短的执行时间以及对控制任务的较优适应时，Modular PID Control 始终适用。

通过 Standard PID Control，可将连续 PID 控制器、脉冲控制器和步进控制器简便集成到应用程序中。使用这一带有集成控制器设置的参数设置工具，可对控制器进行设置，并在较短时间内进行较佳调整，从而节省工程组态成本。步进控制器的控制算法有助于延长执行器的使用寿命。如何找西门子PLC一级代理商

两种控制器都可在 S7-300（CPU 313 及更高）、S7-400 和 WinAC 中使用。

PID Professional 软件包包含 Modular PID Control 和 Standard PID Control 这两个软件包。

两种控制器解决方案均包含调试函数块和标准函数块，适用于广泛的控制器结构。

该调试软件具有直观和易于使用的界面。

还针对这两种控制器提供了大量实施示例。这样就简化了不同控制器结构的实施。

以下现成可用的 PID 控制器提供有 Standard PID Control：

• 带有用于积分末控元件的开关量输出的固定设**控制器
• 带有用于比例末控元件的开关量输出的固定设**控制器
• 多回路比例控制器

• 级联控制器

通过 Modular PID Control 的 27 个标准函数块，用户也可以实施每种所需的控制器结构。为便于学习，提供了清晰而便于掌握的应用示例，有助于实施所需的 PID 控制器。

软件调试

该组态工具已无缝集成到 STEP 7 (TIA Portal) 中。它有如下功能：

• 调试画面：
  该调试软件包含调试 Modular PID Control 和 Standard PID Control 所需的全部画面。
• 使用趋势视图：
  趋势视图用于以图形方式来描绘设**、实际值和操纵变量与时间的关系。趋势视图的值将按组态的时间间隔进行更新。这对于验证过程质量非常有益，可帮助进行故障排除。
• 控制电路优化向导：
  使用 PID Self-Tuner，即使不具备控制系统方面的任何知识，也可进行清晰而简便的控制器优化和调试。
• 使用连续 PID 控制器时的可变瞬态响应：
  可以对控制回路的瞬态响应进行预先选择，以使控制回路在发生大约 10% 过冲后稳定下来，从而取得动态响应。若不需要这样，则可以设置非周期的稳定（无过冲）。
• 用户友好的关联帮助：
  在程序中的任何位置，都可根据需要获得相应帮助。

Standard PID Control 功能

Standard PID Control 的控制器结构进行了预组装，数据结构也是固定的。通过软件开关，可以打开和关闭以下功能：

• 通过设**值发生器、斜坡/恒值、归一化、函数调用、设**斜坡限制（斜坡函数发生器）以及设**限制进行设**处理。
• 通过定标、平滑、平方根、函数调用、限值监视以及实际值梯度监视进行实际值处理。
• 通过死区和限值监视进行错误信号处理。
• PID 算法，对于带和不带位置反馈的步进控制器。
• 通过手动/自动切换、手动值发生器、函数调用、设**梯度限制、设**限制和归一化进行操纵值处理。

标准函数块

PID Professional V11 的应用示例

• Low-priced package for simple, controlled positioning and simple geared synchronous motion
• For use with any standard variable-speed drive, such as frequency converter or servo drive
• For incremental and absolute encoders

Easy Motion Control is a low-cost package for simple, controlled positioning and simple geared synchronous motion of several axes. It is suitable for use with any standard variable-speed drive, such as frequency converter or servo drive

Incremental and absolute encoders are supported.

Possible applications include, for example:

• Single operating axes,
• Positioning/setup axes
• Palletizers,
• Feeder units or
• Material transport

in the following industries:

• Warehousing systems,
• Woodworking and metalworking,
• Packaging,
• Paper processing,
• Food and beverage industry and many others.

Easy Motion Control comprises:

• Configuration and commissioning user interfaces for STEP 7
• Function blocks for controlled positioning and geared synchronous motion.
• Drivers for SIMATIC modules: 
  The actual position value is input and the setpoint speed is output via modules from the standard SIMATIC range. Matching driver blocks are included with the most common modules. Additional modules can be linked by means of an open driver (see Technical specifications).
• Drivers for DP coupling to MM4.
• Drivers for coupling the IM 174 or SINAMICS S120 interface module via PROFIdrive profile (Easy Motion Control V11 or higher)
• Configuration software for parameter assignment and commissioning: 
  The handling of the configuration software is supported by an online help.
• Sample programs for various applications to make it easier to get started.

Easy Motion Control is executable on all SIMATIC CPUs above a certain performance class (see Technical specifications).

Licensing

The function blocks of Easy Motion Control require one runtime license for each CPU onto which they are loaded.

The engineering interface for STEP 7 (TIA Portal) is included in Easy Motion Control V11 or higher and requires one floating license per installation used, which is provided by a CoL and a license key on a USB flash drive.

Packaging

• Easy Motion Control for TIA Portal, floating license and single license (runtime), 
  comprising
  • a CoL for the configuration software,
  • a USB flash drive with a license key for the configuration software and
  • a CoL for one runtime license.
• Easy Motion Control, floating license download comprising
  • Online delivery of a floating license for the configuration software by email
• Easy Motion Control runtime license, without software or documentation, comprising
  • a CoL for one runtime license (valid for V2.x and V11 or higher)

Software and documentation are already included in the STEP 7 package V13 or higher.

Easy Motion Control offers the following basic functions for positioning:

• Move absolute: 
  The axis moves to the specified position. With rotary axes, the target can be approached in a positive or negative direction or on the shortest possible path.
• Move relative: 
  The axis moves by the specified distance in a positive or negative direction.
• Reference point approach, reference setting: 
  Synchronizes the measuring system with the mechanical system.
• Gearing: 
  Axis moves to a different axis in gearing.
• Jog: 
  The axis moves for as long as the control bit for one direction is present.
• Stop: 
  Stops the motion and brings the axis to a standstill.
• Simulation: 
  A program can be tested in the simulation even if a real axis is not present and no actual values can be read in.
• Override: 
  A factor between 0 und ** can be applied to the speed of the motion at any time. Acceleration and deceleration are not influenced by this.
• Override travel motion: 
  Any motion block can override any other motion block. The current motion is transferred to the new motion with the specified acceleration or deceleration.如何找西门子PLC一级代理商

Further function blocks must be additionally integrated into the user program, such as the position controller and input/output drivers.

The Easy Motion Control block is called in a time-driven level, e.g. a cyclic interrupt.
