Solutions Overview CONTENT LIBRARY LCON FOR THE TIA-PORTAL LCon Library is not using any motion control functionality of the controller and is executable on all controllers of the type S7-300 and S7-400. LCon Library is not using any motion control functionality of the controller and is executable on all controllers of the type S7-1200, S7-1500 and S7-1500T. LConSMC Standard Motion Control Library is using standard motion control functions of the controller to realize winding and tension control. It is executable on the controllers S7-1500 and S7-1500T in combination with technology objects. Both solutions for S7-1500 offer the same functionality for winding and tension control. In case of further technological functions like flying splice, traverser or general positioning commands the solution offers a standard control and diagnostic interface via technology objects based on standard motion control system functions.
