SIMATIC Winder and Tension Control

  • Entry
  • Associated product(s)
The SIMATIC application Winder and Tension Control is part of the Converting Toolbox and was developed with the objective to provide common functions which are necessary for any kind of converting machine.

The application is technological foundation for many kinds of finishing processes and provides comprehensive functions to realize winding or tension control functionality.
It contains control loop function blocks using dancer systems, load cells as well as indirect tension control. Furthermore specific functions like torque pre-control, diameter calculation or tension taper.

Content of the SIMATIC library LCon in TIA-Portal 
S7-300 / S7-400

The library does not use motion control functionality of the controller.

It can be used on S7-300 and S7-400 controllers.

S7-1200 / S7-1500(T)

The library does not use motion control functionality of the controller.

It can be used on S7-1200, S7-1500 and S7-1500T controllers.


LConSMC - Standard Motion Control

The library uses motion control functionality of the controller to realize winding and tension control functionality (technology object is required).

It can be used on S7-1500 and S7-1500T controllers.

Both options for S7-1500 offer the same functionalities in order to realize a winder or tension control solution. In case there are further technological functionalities required, like flying splice, traversing winding or general positioning tasks, the S7-1500(T) solution offers a unique access via technology objects based on the standard motion control functionality.
