Module overview
Description
The multi-facetted module range of S7-300 allows modular customization to suit the most varied tasks.
Function modules are intelligent modules that independently execute the technological tasks like counting, measuring, cam control, PID control and motion control. Thus they reduce the load on the CPU.
They are used when a high level of accuracy and dynamic response is required.
Applications
-
Wood, glass, stone and metal processing
-
Packaging machines
-
Presses
-
General machine manufacturing
-
Machine tools
-
Textile machines
-
Rubber and plastic industry
-
Plants
Benefit
-
High degree of accuracy and dynamic response
-
Specialized and universal modules with a wide range of functions
-
CPU is not involved since the functionality is stored in the firmware of each module
-
Quick reaction times (deterministic dynamic response)
-
Engineering with configuring tool, integrated into STEP 7
Design and function
Function modules are intelligent modules that independently execute the technological tasks and thus reduce the load on the CPU.
Configuration tools based on STEP 7 and STEP 7-Micro/WIN are available for setting parameters. Parameterization and commissioning are performed via user-friendly screens.
The function modules of the S7-300 can also be used in a distributed configuration in the
ET 200M I/O system – also with PC-based automation with WinAC.
