Modular PID Control

Loadable function blocks for complex control structures

Description

Modular PID Control

Modular PID Control is a library of standard function blocks that are optimally tuned to each other.

They can be used to implement any type of controller structure for SIMATIC S7-300/400, C7 and WinAC in process engineering applications. In combination with the SM 334 analog module, sampling times of up to 5 ms are possible. The function blocks are easily interconnected in STEP 7, SCL and using graphical techniques in CFC.
Complex control structures can be generated clearly, flexibly and tested. The associated parameterization software contains a control loop display with bar charts and a graphic plotter for indicating the signal charts. This makes commissioning much easier.

Notice on product versions
Modular PID Control is an option for STEP 7 V5.6 rsp. STEP 7 Professional 2010 for controllers of the SIMATIC S7-300/S7-400 family, SIMATIC C7 and SIMATIC WinAC.
When employing STEP 7 (TIA Portal) for the engineering of these controllers you need the option package PID Professional instead.

Modular PID Control is used for applications where extremely complex control structures have to be constructed. Modular PID Control is also suitable when memory space has to be saved and single controllers from the building block set meet the requirements exactly.

Modular PID Control is recommended when analog calculation blocks including dead zone, polygon, standardization or time scheduler are used.

The following controller types exist

  • Continuous-action PID controller

  • Pulse controller

  • Step controller


Area of application

Prepared examples

  • Fixed value controller with different output

  • Single-loop ratio controller

  • Multi-loop ratio controller

  • Blending controller

  • Cascade controller

  • Controller with pre-control

  • Controller with feedforward control

  • Range selection controller

  • Override controller

  • Multivariable controller


Design and functions

Functions according to Standard PID Control

  • Test functions

  • Controller optimization

  • Transient response without overshoot

  • Control algorithm for step controller

For online self-optimization of temperature control loops, the combination with the > PID Self Tuner is recommended

Licensing

  • Modular PID Control comprises the parameterization tool (Engineering Software) and function blocks (Runtime Software).

  • The engineering software can be installed on as many computers as you like.The number of licenses determines the number of computers the software can be used on at one time. (Floating License)

  • Function blocks may be copied as often as required onto any programming devices/PCs. However, one license is always required per CPU on which they are used.
